If anyone's reading this, and I doubt anyone is, I'm hoping you guys have a great summer. I was bored, so I decided to post this. Bye.

Tear's Growing Post for June 6th

Question 1:

Formulas. We’ve learned how to write algebraic equations in the form of mx + b = y. Convert these two sentences into algebraic equations using the above formula.

m- This is the coefficient.
x- This is the variable.
b- This is the constant.
y- This is the answer or the solution of a formula.

Coefficient - Is the number that is teamed with the variable and in this case the variable is x.

Variable- Is the letter that represent numbers. They vary in that we can substitue a variable for one or more numbers.

Constant- It's value never changes in an expression.

Sentence 1:
Scott is 2 years older than Donald who turns 12 on June 21st 2006. Write this sentence in the format of mx + b = y, then convert it into an expression which allows us to figure out the age of Scott.

Solution:

Donald + 2 = Scott
D + 2 = S
11 + 2 = S
13 =S

I color coded my solution so it's easier to understand. Donald's age is in green and Scott's age is in purple and the black number is the constant. Donald's age is my starting point.

Donald's age is 11 because he didn't turned 12 yet and the problem says that Scott is 2 years older than Donald. So 11 + 3 = 13.

That's how I got Scott's age which is 13 years old.

Sentence 2:
Elizabeth has $200 in her savings account. She makes $40 every two weeks babysitting for her next door neighbours. If Elizabeth saves all of her money solve for how much money she will have in one year.
Equation: 200 + 40n= total money for one year.
Solution:

200+40n =$ In my solution every month has 4 weeks only.
200+40(24)=$ My variable is n and it's value is 48(which is in the
200+960 = $ brackets because if she makes $ 40 in every 2 weeks
1,160=$ then she makes $ 80 per month. If there are 12 months
you multiply 80 by 12 which gives 960.

I color coded my solution again. The number on green is my constant and it is my starting point. The number in golden yellow is my coefficient. The letter in sky blue is my variable. On this problem I'm solving for the value of this symbol: $ .

My starting point is 200 because that is her money in her savings acount. I got 40 as my coefficient because she makes $ 40 every 2 weeks. So this symbol: $ has a value of 1,160 which means Elizabeth will have $1,160 in one year.

Question 2:

Creation. You need to create two questions for your classmates that cover different concepts (ex: T-Charts, patterns, equations, graphs etc.) that you have learned in this unit on Algebra. You then need to show how to solve the questions. Your mark will be based upon the level of question’s difficulty, and the effort put into your answer.

To solve this problem correctly, you have to make an equation, a T-Chart, a graph and lastly you have to explain what is the pattern.

Question 1

Solve for Step 4, step 5 , step 10 and step 50. First explain the pattern. Second, make an equation. Third make a T-Chart . Fourth make a Graph.

First: Pattern Explanation:

In Step 1, there's 3 t-shirts in total, they form the capital L shape 1 t-shirt on line 1 and 2 t-shirts on line 2. For example, when you look at it there's 2 t-shirt vertically and 2 t-shirts horizontally.
In Step 2, there's 5 t-shirts in total, 3 vertically and 3 horizontally.This 5 t-shirts also form the capital L shape.

In Step 3, there's 7 t-shirts in total , 4 vertically and 4 horizontally.This 7 t-shirts also form the capital L shape.

The pattern goes like this:
Every new step, you add 2 t-shirts, one to the vertical line and 1 to the horizontal line.

Second : Equation

3+2n=

For example:

3+2n=

3+2(4)=

3+8=11

Third: T-Chart

On the t-chart above you could see the pattern better.

Fourth: Graph

The graph above shows that the pattern is increasing not decreasing.

Problem 2

Margaret has 10 marbles more than Lisa and the total marble they have all together is 34 marbles. If Lisa keeps adding 2 marbles every other day and Margaret only adds 1 marble everyday. How many would Margaret and Lisa have after 30 days and who will have more marbles. How much is the difference?

To solve this problem you have to do it step by step.

First, solve how many marbles Lisa have. Margaret has 10 more marbles than Lisa so you have to subract 10 marbles from 34 to make is equal then you divide it by 2 to figure out how many Lisa has. For example:
34 - 10 = 24
24 / 2 = 12
12 = Lisa's marbles

Second, you figure out the pattern.
The pattern goes like this for margaret.
Margaret started with 22 marbles and she adds 1 marble everyday.
The pattern goes like this for Lisa.
Lisa started with 12 marbles and she adds 2 marbles every other day.

Third, make an algebraic equation.
Margaret: 22 + 1m= # of marbles
Lisa : 12 + 2m= # of marbles

Fourth, solve it.
Margaret:
22 + 1m =
22 + 1 (30)=
22+ 30 = 52

Lisa:
12 + 2m
12 + 2 (15)=
12 + 30=42

For Lisa, the number on the bracket is 15 because she adds marbles only every other day. So I divided 30 by 2 to figure out the number of marbles Lisa will have.

ANSWER:
Margarett has 52 marbles after 30 days and Lisa only has 42. So it shows that Margaret has more marbles. The difference between Marget's number of marbles to Lisa's number of marbles is 10. To solve that you subtract 52 from 42 and it gives 10.

I made a t-chart below to show the pattern because the pattern is easier to see here. You can also see that Margaret has more marbles from the start.

I made a graph below to show it is increasing and it is easier to see that Margaret has more marbles that Lisa.

Question 3:

Reflection: You need to look back at the chart that we filled out during the first day of the unit. THis is the chart where you coloured a topic red, yellow or green. You now need to pick one concept that you coloured yellow or red and reflect in words what new skill/idea that you have learned on this topic.

Can I create a T-chart for my pattern?

When I read that question on the chart, the question seemed familiar to me because we learned about patterns last year in grade 6.But the word t-chart is unfamiliar to me but when we talked about it in class this year I understand it now. I learned that what you put on the t-chart depends on the pattern. So to make a t-chart you have to figure out the pttern first.

Question 4:

Preparing for the final exam. You need to think about the year that has past in mathematics and decide which topic is your weakest, and what you need to learn during class review in order to prepare yourself for the final exam. It is not enough to say fractions, instead pick your weakest area of fractions, say the subtraction of fractions, and give an example of what you don’t understand.

One topic on the exam I know I'll have a mistake on is about Integers especially Word problems about Integers. That's the topic I know I have to study hard for the exam because I get confused to what the word problem meant sometimes. One word problem I got confused on is below.

When Craig woke up this morning it was 7 below zero outside. By noon the temperature had reached 2 above and by late afternoon the temperature had peaked at 5 above. What is the total change in temperature today?

I got confused about this question. I thought the question meant was what is the temperature after all the temperature change so I put this as the answer:

(-7)+(+2)+(+5)=0

The correct answer was 12 because from -7 to +2 the temperature went up by 9 degrees and from +2 to +5 the temperature went up by 3 degrees. So 9 degrees plus 3 degrees it equals to 12 degrees.

So the total change in the temperature today is 12 degrees.

Question 1: Formulas. We’ve learned how to write algebraic equations in the form of
mx + b = y. Convert these two sentences into algebraic equations using the above formula.

Sentence 1: Scott is 2 years older than Donald who turns 12 on June 21st 2006. Write this sentence in the format of mx + b = y, then convert it into an expression which allows us to figure out the age of Scott.

D + 2 = L
11 + 2 = L
11 + 2 = 13

I put 11 because Donald is 11 years old. I added 2 to find out how old is Scott.

>> Scott is 13 years old.

Sentence 2: Elizabeth has $200 in her savings account. She makes $40 every two weeks babysitting for her next door neighbours. If Elizabeth saves all of her money solve for how much money she will have in one year.

200 + 40c = L
200 + 40(24) = L
200 + 960
L = 1,160

I put 24 for c because Elizabeth makes $40 every 2 weeks. (12 + 12 = 24)

So then I multiplied 40 by 24 together. Then I added 200 and 960 together.

>> Elizabeth will have $ 1,160 in one year.

Question 2: Creation. You need to create two questions for your classmates that cover different concepts (ex: T-Charts, patterns, equations, graphs etc.) that you have learned in this unit on Algebra. You then need to show how to solve the questions. Your mark will be based upon the level of question’s difficulty, and the effort put into your answer.

Question # 1: Create the next two patterns. (Pattern # 3 and Pattern # 4). Also, tell me what is going on with the patterns. For Bonus Question, what letter do you think it is? (:

The pattern is adding 1 block to both ends of the shape.

Every time you add 1 block to both ends, the shape goes bigger.

The letter is “L”

Question # 2: Create a T-chart for the patterns you did and write an expression.

Expression: 9 + 2 (L) =

It starts of by 9 because for Pattern # 1, there’s 9 blocks and you add 2 every time you make a new pattern.

Question 3: Reflection. You need to look back at the chart that we filled out during the first day of the unit. This is the chart where you coloured a topic red, yellow or green. You now need to pick one concept that you coloured yellow or red and reflect in words what new skill/idea that you have learned on this topic.

COLOR RED – Can I create a T-chart for my pattern?

- Well before in the very beginning of Algebra Unit, I didn’t have any idea how to create a T-chart for a pattern. But then as we moved on the unit.. I learned how to do this and solve some algebra equations.

Question 4: Preparing for the final exam. You need to think about the year that has past in mathematics and decide which topic is your weakest, and what you need to learn during class review in order to prepare yourself for the final exam. It is not enough to say fractions, instead pick your weakest area of fractions, say the subtraction of fractions, and give an example of what you don’t understand.

I think my weakest is Combing The Opposites. I don’t really get it…
I need to learn mostly all the stuff we did in math.

This is the example of a Combining The Opposites:

(+5) – (+2) =
(+5) + (-2) = +3

++ Mr. Reece, the fonts are supposed to be different colors but i dont know what happened ..because i did this on Microsoft Word (Blogger).

1. What is meant by the terms "rotation symmetry" and "reflection symmetry?" How does this relate to pentominoes?Pentominoes are shapes that could be form using 5 squares. The pictures on the left are the 12 unique pentominoes.
Rotation symmetry or rotating any shape makes an identical shape of the original shape. Using the method of rotation symmetry to a pentomino will make a different but still similar pentomino. This does not make the new pentomino unique. Because it has a similar pentomino.
Reflection symmetry or flipping any shape makes a mirror image of the original shape. Also, using this method to a pentomino makes the mirror image of the original pentomino. It doesn't make the pentomino unique because it has a very similar image ^_^ .
2. Create a pattern. You must represent this pattern both pictorially ( i.e. with picture or diagram ) and with numbers. You must show the first 4 steps of your pattern.
shape # 1

shape # 2

shape # 3

shape # 4

3. Describe in words what is occurring with your pattern and if your pattern has an ending or if its continues on indefinately.
This shape is like stairs. It started as a 3 blocks by 3 blocks figure ( shape # 1 ). You keep adding the next set of blocks at the bottom and the bottom-right corner of the shape. So if you add the next set of blocks the shape will be longer at the left side and at the bottom side, like what is happening to the next 3 shapes. This pattern continues on and on forever. It adds more and more set of blocks than anyone could imagine.
4. Create a T-chart that shows what is happening with your pattern.
To get shape 6 and shape 8 you must figure out a formula that works for every shape with or without shape 1. I can't figure out the formula so what I did is count. I'll try to figure out the formula but in the mean time I'm done my post.

Question 1: Formulas. We've learned how to write algebraic equations in the form of mx + b = y. convert these two sentences into algebraic equtaions using the above formula.

M = this is the coefficient, these are the numbers that are teamed with the variable.
X = this is the variable, these are the letters that represents numbers. They vary in that we can sunbstitute a variable for one or more numbers.
B = this is the constant, their value never changes in an expression.
Y = this is the solution of the question

Sentence 1: Scott is 2 years older than Donald who turns 12 june 21st 2006. Write this sentence in the format of mx + b = y, then convert it into an expression which allows us to figure out the age of Scott.

D = Donald S = Scott

D + 2 = S

11 + 2 = S

11 + 2 = 13

Donald is currently 11 years old.
Since Scott is older than Donald by 2 years.
Scott is 13 years old. 2 years older than Donald.

Sentence 2: Elizabeth has $200 in her savings account. She makes $40 every two weeks babysitting for her next door neighbours. If Elizabeth saves all of her money solve for how much money she will have in one year.

200 + 40n =

200 + 40(24) =

200 + 960 = 1160

The variable is 24 because since 1 month has 4 weeks and Elizabeth receives $40 every 2 weeks that would make 24 weeks.
Elizabeth will have $1160 in her savings account.

Question 2: Creation. You need to create two questions for your classmates that cover different concepts (ex: T-Charts, patterns, equations, graphs etc.) that you have learned in this unit on Algebra. You then need to show how to solve the questions. Your mark will be based upon the level of questions difficulty, and the effort put into your answer.

Question 1: You are going shopping for clothes. Each t-shirt costs $20, shorts costs $10 and socks costs $5. You have with you $155. You are trying to get the same amount of everything. How many shirts, shorts and socks can you get so you have the same number of each type of clothing.

You can buy 5 shirts, shorts and socks.
5 shirts will cost $60.
5 shorts will cost $50.
5 socks will cost $45.
Add them up - $155

Question 2: You have $50. Every month you receive $300. How much will you have in 3 years?

50 + 300n =
50 + 300(36) =
50 + 10800 = 10850

Since there are 12 months in one year. 3 years would have 36 months. 12 months * 3 years = 36 months.
In 1 year you would have 3650.

In this chart you will see how much you started with, how much you'll have in 1 and 2 years and you answer: You'll have $10850 in 3 years/ 36 months.

Question 3 : Relection. You need to look back at the chart that we filled out during the first day of the unit. This is the chart where you coloured a topic red, yellow or green. You now need to pick one concept that you coloured yellow or red and reflect in words what new skill/idea you have learned on this topic.

I pretty much learned everything. From T-Charts to Graphs to algebraic formulas. We did this last year, but i didn't really understand it. I learned alot.

The thing I mostly learned was the formulas. I have learned that whatever you do to one side you have to do the same on the other side (other side of "=" sign). The Coefficient, variable, constant thing. I also learned how to put t-charts and graphs into formulas and find out way more than the graph or t-chart is supposed to go.

Question 4: Preparing for the Final Exam. You need to think about the year that has past in mathematics and decide which topic is your weakest, and what you need to learn during class review in order to prepare yourself for the final exam. It is not enough to say fractions, instead pick your weakest area of fractions, say the subtraction of fractions, and give an example of what you don't understand.

Algebra: Showing the steps for some questions.

(8 - 3)n + 7n + 8 = 4n + 40

5n + 7n + 8 = 4n + 40

12n + 8 = 4n + 40

12n - 4n + 8 = 4n + 40 - 4n

8n + 8 = 40

8n + 8 - 8 = 40 - 8

8n = 32

8n/8 = 32/8

n = 4

mx+b=y
m-is the coefficient, which is combined with the variable
x- this represents numbers. x is the variable. the numbers it reprsents may vary because you can subsitute it with one or more numbers.
b- is the constant. The constant will never ever change in an expression.
y- is the solution to a formula.
Question 1:Formulas. we've learned how to write algebraic equations in the form of mx+b=Y. Convert these two sentences into algebraic equations using the above formula.

sentence 1: Scott is two years older than Donald who turns 12 on June 21st 2006. Write this sentence in the format of mx+b=y, then convert it into an expression which allows us to figure out the age of Scott.

D=the age of Donald S=the age of Scott
D+2=S
11 + 2 = S
11 + 2 = 13
Scott is 13 years of age

Since Donald is turning 12 on June 21st he is still 11, there for if Scott is two years older than Donald, then that would make Scott 13 while Donald is 11.

sentence 2: Elizabeth has $200 in her savings account. She makes $40 every two weeks babysitting for her next door neighbors. If Elizabeth saves all of her money solve fo rhow much money she will have in year.
The formula for the is [ 200x + 40 = y ]
200+ 40n = y
200 + 40(24) = y
200 + 960 = y
200 + 960 = 1160

Question 2: Creation. You need to create two questions for your classmates that cover concepts (ex. T-Charts, patterns, equations, graphs etc.) that you have learned in this unit on Algebra. You then need to show how to solce the questions. Your mark will be based upon the level of questions deifficulty, and the effect put into your answer.

1) It's the first day of June and you decide to start saving up your weekly allowence in a piggy bank because you are going to Edmonton on the first week of July. You start off with $200 in your piggy bank, and your dad gives you $20 dollars each week. How much money will you have by the end of this month?

200 + 20 n = solution
200 + 20 (5) = solution
200 + 100 = solution
200 + 100 = $300
you will have $300 by the time you go to Edmonton because there are 5 weeks in June so you multiply 20 by 5 then you add the coefficient with the constant then you get you solution.

Question 3: Reflection
You need to look back at the chart that we filled out during the first day of the unit. This is the chart where you coloured a topic red, yellow or green. You now need to pick the one concept that you coloured yellow of red and reflect in words what ned skill/ idea that you have learned on this topic.

In algebra I've learned how to create algeraic equations. And the other things just refreshed my memory on what i already knew but forgot.
I used to hate creating algebraic formula's because I always got frustrated trying to figure out which number goes where. But now that I understand it i wont get as frustrated as before.
solving equations used to take me so long to do because it kind of took me a while to understand what the questions wants me to do. But now i know exactly how to solve Equations.
For example, if you add subtract or ect. to one side then you have to do it to the other side of the = sign for you to get the correct answer.

Question 4: Preparing for the final exam.
You need to think about the year that has past in mathematics and decide which topic is your weakest, and what you need to lear during class reveiw in order to prepare yourself for the final exam. It is not enough to say fractions, instead pick you weakest area of fractions, say the subtration of fractions, and give and example of what you don't understand.

creating a word problem for algebra. It's hard for me to think of what the problem should have and how many numbers or the topic of the problem.

Question 1: Formulas. We’ve learned how to write algebraic equations in the form of mx + b = y. Convert these two sentences into algebraic equations using the above formula.

mx + b = y

m- This is the coefficient. It is teamed with the variable which is x
x- This is the variable. It represents numbers. They vary in that we can substitute
a it for one or more numbers.
b- This is the constant. It never changes in an expression
y- This is the answer or the solution of a formula.

Sentence 1: Scott is 2 years older than Donald who turns 12 on June 21st 2006. Write this sentence in the format of mx + b = y, then convert it into an expression which allows us to figure out the age of Scott.

Donald + 2 = Scott
D + 2 = S

11 + 2 = S
11 + 2= 13

- Donald's age which is eleven plus two years is equal to thirteen.
- Scott is 2 years older than Donald so he will be 13 years old. While Donald is 11 years old.

Sentence 2: Elizabeth has $200 in her savings account. She makes $40 every two weeks babysitting for her next door neighbours. If Elizabeth saves all of her money solve for how much money she will have in one year.

200 + 40n= x
200 + 40 ( 24 )= x
200 + 960 = x
1160 = x
or
x = 1160

Question 2: Creation. You need to create two questions for your classmates that cover different concepts (ex: T-Charts, patterns, equations, graphs etc.) that you have learned in this unit on Algebra. You then need to show how to solve the questions. Your mark will be based upon the level of question’s difficulty, and the effort put into your answer.

FIND THE MISSING STEPS.

Step 1: 2
Step 2: 4
Step 3: 8
Step 4: ?
Step 5: ?

The pattern of this one is like its root number (did I say that right?). Step one has 2 flowers so you mutliply it by itself then you get 4. So for Step 3 it has 8 flowers... multiply it by 8 then you get 64.

Step 4: 64
Step 5: 4096 ('o')

Step # 1: 2

Step # 2: 4

Step # 3: 8

Step # 4: 64

Step # 5: 4096

THIS GRAPH EXPLAINS YOU IF THE FLOWERS ARE INCREASING OR DECREASING. SO OBVIOUSLY THE GRAPH IS INCREASING.

Question 3: Reflection. You need to look back at the chart that we filled out during the first day of the unit. This is the chart where you coloured a topic red, yellow or green. You now need to pick one concept that you coloured yellow or red and reflect in words what new skill/idea that you have learned on this topic.

Can I use in my words to create my algebraic formula?
BEFORE- red
AFTER- yellow

When I read that question, I thought that I;ve heard it before but I've never learned about it before. I know what algebra is but I can't make my own algebraic formula yet. In the middle of the algebra unit, I started getting how to make one. Until at the end, I get it!...but I still need to review more about it for the exam. That's all thank you!

Can I use an algebraic formula that I created to solve an unknown (n)?
BEFORE- red
AFTER- yellow

When I was thinking about algebra...I couldn't remember anything about algebraic formulas. When I was in grade 6 we learned about leaner equations but I didn't really understand it taht time. In grade 7 when we started the Algebra unit, I learned a lot more about it. I learned how to make an algebraic formula.

Question 4: Preparing for the final exam. You need to think about the year that has past in mathematics and decide which topic is your weakest, and what you need to learn during class review in order to prepare yourself for the final exam. It is not enough to say fractions, instead pick your weakest area of fractions, say the subtraction of fractions, and give an example of what you don’t understand.

My weakest area- ALGEBRA!
In algebra I had a hard time solving word problems. It's like when there's a paragraph containing clues and ways how to solve that problem. It gave me a hard time understanding them and making the formula but when the problem is really easy I find it really easy to create the formula. So during class review I will spend more time in Algebra and other topics that I need to refresh in my mind.

I will post an example of a problem when I get my Algebra test back! ^_^

im only giving the answers

1) algebraic expression represents variables, we can substitute one or more number for the letters in the algbriac expression and it does not habe an equal sign

an algebraic equation, the number of the variable is given and you need to solve the numbers to get the appropriate number for the variable

the difference is the variable for the expression is not given while the variable for the equation is given and it has equal sign.

2) variable is the letter in algebraic expression and equation (likex,y). we use that to represent the unknown number. to find it out use START +CHANGE(VARIABLE)

3) solve for N

4)
a)3n+4n+7=2n+12n
b)8n-(4+9)=11
c)(8-3)n+7n+8+4n+40

5) for this question you need to create a T-chart and a graph to plot your data onto paper

------Questions for June 6th------

1. Formulas. We've learned how to write algebraic equations in the form of mx + b = y. Convert these two sentences into algebraic equations using the above formula.

m - coefficient ( change )

x - variable

b - constant ( start )

y - solution

Sentence 1. Scott is 2 years older than Donald who turns 12 on June 21st, 2006. Write this sentence in the format of mx + b = y, then convert it into an expression which allows us to figure out the age of Scott.

D + 2 = S

D is Donald's age.

S is Scott's age.

The equation represents that Donald's age plus 2 gives you Scott's age.

Right now Donald is 11 years old.

11 + 2 = S

11 = S

Scott is 13 years old.

Sentence 2. Elizabeth has $200 in her savings account. She makes $40 every two weeks babysitting for her next door neighbours. If Elizabeth saves all of her money solve for how much money she will have in one year?

40x + 200 = y

40 is the coefficient or how much the change of her savings account every two weeks.

x is our variable. In this question it represent how many 2 weeks.

200 is the constant. It's the amount of money she already have.

1 year has 12 months and each month has about 4 weeks in it. So every month has 2 two weeks.

12(2) = 24

Now our variable represent 24.

40x + 200 = y

40(24) + 200 = y

960 + 200 = y

1160 = y

She will have $1160 in her account in one year.

2. Creation. You need to create two questions for your classmates that cover different concepts ( ex: T-charts, patterns, equations, graphs etc. ) that you have learned in this unit on algebra. You then need to show how to solve the questions.

Question 1. You are in your school's bake sale. A small pie costs $5.00, a medium pie costs $7.50 and a large pie cost $10.00. You planned to buy one medium and large and as many small ones as you can. You have $50.00. How many small pies can you buy if you are also buying 1 large and 1 medium?

The graph shows that you can buy 8 small pies if you are also buying 1 medium pie and 1 large pie.

Question 2. You have $10.00. Every week you earn $50.00 for working and spends $10.oo for shopping. How much money would you have in six weeks?

Every week you earn 50 and loses 10.

(50 + 10)x + 10 = y

So 50 - 10 = 40. Every week you earn really 40.

So our expression is 40x + 10. x is our variable. For this question it is the number of weeks.

Each month has about 4 weeks. So 6(4) = 24 weeks.

Our variable represent 24 weeks.

40x + 10 = y

40(24) + 10 = y

960 + 10 = y

970 = y

In 6 months you will have $970.

3. Reflection. You need to look back at the chart that we filled out during the first day of the unit. You now need to pick one concept that you coloured yellow or red and reflect in words what new skill that you learned on this topic.

Using T-charts to create an algebraic formula.

You may know what a t-chart is in the beginning of the unit. But you might not know what an algebraic formula was. It has coefficient, variable and constant or what we used to know as start, change and variable.

This is an example of a t-chart. In the left column is the variable, x. In the right column is the solution, y.

The algebraic formula is mx + b = y.

The left side of the column is x. The right side is going to be the solution.

1x + 7 = y

Step 3 :

1(3) + 7 = y

3 + 7 = 10

The formula didn't work so minus the extra 1 in the formula.

1x + 7 - 1 = y or 1x + 6 = y

1(3) + 6 = y

3 + 6 = 9

4. Preparing for the final exam. You need to think about the year that has past in mathematics and decide which topic is your weakest, and what you need to learn during class review in order to prepare yourself for the final exam. It is not enough to say fractions, instead pick your weakest area of fractions, say the subtraction of fractions, and give an example of what you don’t understand.

Integers. Any positive or negative numbers without decimals.

Multiplying Two Negative Integers. Multiply the numbers and the symbol is always positive.

(-4)(-5) = +20

The End

Questions due Tuesday May 30th (Created by Boeun)

#1 What is the difference between an algebraic expression and an equation (hint: One contains this and the other doesn’t)? Give an example of both an expression and an equation.

- They all have variable, starting point, and change. The letter of the variable doesn't matter. It can be A B C D E F G… any alphabets we can use. What matter is that does the variable in an algebraic equation or expression is given. In an equation the value of the variable is already given to balance each side of the equal sign.

Example of an expression is 5n x 2 and example of an equation is this. 5 x 2 = 10

#2 What is variable and why do we use one in algebra?

- Variable means unknown number. We don’t know the number that is unknown so we are using alphabet to make expression so we can solve it and get variable

#3 Solve N
- One circle is equal to 1. All 9 circles are equal to 9. Two squares are equal to 4. One triangle is equal to 5 so 9-4= 5.
- 6 squares are equal to 12 so 12 + 5 + 5= 22
- 22 divided by 2 is 11, then N is equal to 11

#4 Solve the following equations. Show all of the steps that are needed

a) 3n + 4n + 7 = 2n + 12

3n + 4n + 7 = 2n + 12

7n + 7 = 2n +12

7n + 7 = 2n + 12

- 2n -2n

5n + 7 = 12

- 7 - 7

5n = 5

5 ÷ 5 = 1

n = 5

b) 8n – (4+9) = 11

8n – (4+9) = 11

8n – 13 = 11

+ 13 + 13

8n = 24

24 ÷ 8 = 3

n = 3

c) (8 - 3) n + 7n + 8 =4n + 40

(8 - 3) n + 7n + 8 =4n + 40

5n + 7n + 8 =4n + 40

12n + 8 = 4n + 40

- 4n -8 -4n -8

8n = 32

32 ÷ 8 = 4

n = 4

#5 For this question you need to create a T – Chart and a graph to plot your data from this question onto.

You are having a race against your friend, except you are on foot and he is on his bike. You both know that if you are on a bike you will be faster so your friend gives you a head start of 3 minute, who will be the first to make it to the finish line 2000m away?So you will win by 600m.

Question #1: What is the difference between an algebraic expression and an equation (hint: One contains this and the other doesn't)? Give an example of both an expression and an equation.

An Algebraic Expression is when the value of the variable is already given to you.

Example

7 + 5(3) =

7 + 15 = 22

An Algebraic Equation is when the variable is given to you but is still an unknown.

Example

20 + 5a =

20 + 5(15) =

20 + 75 = 95

Question #2: What is a variable and why do we use one in algebra?

A variable represents an unknown quantity that we are trying to solve for. We use variables in algebra because it can help you solve the problem more easier and faster.

Question #3 Solve for N

Question #4 Solve the following equations. show all of the steps that are needed.

a) 3n + 4n + 7 = 2n + 12

7n + 7 = 2n + 12
7n - 2n + 7 = 2n - 2n + 12
5n + 7 = 12
5n + 7 - 7 = 12 - 7
5n = 5
5n/5 = 5/5
n = 1

b) 8n - (4+9) = 11

8n - 13 = 11
8n - 13 + 13 = 11 + 13
8n = 24
8n/8 = 24/8
1n = 3
n = 3

c) (8 - 3)n + 7n + 8 = 4n + 40

5n + 7n + 8 = 4n + 40
5n + 7n + 8 - 8 = 4n + 40 - 8
12n = 4n + 32
12n = 36n
12n/12 = 36/12
n = 3

Question #5 For this question you need to create a T-Chart and a graph to plot your data form this question onto.

You are having a race against your friend, except you are on foot and he is on his bike. You both know that if you are on a bike you bill be faster, so your friend gives you a head start of 3 minutes. If you can run 400m per minute, and you friend can bike 700m per minute, who will be the first to make it to the finish line 2000m away?

You would win the race as you can see...

Question #1: What is the difference between an algebraic expression and an equation (hint: One contains this and the other doesn't)? Give an example of both an expression and an equation.

An algebraic equation is when the variable is given and it's when you have to solve for the variable.
Example -
3 + 2r = 10
3 + 2(1) =
3 + 2 = 5

An algebraic expression is when the variable is chosen as a number.
Example -
4 + 5(2) =
4 + 10 = 14

The difference is the equation has the variable already given and the expression is when the variable is shown as a number.

Question #2: What is a variable and why do we use one in algebra?

A variable is an unknown quantity that we are trying to solve for.
We use variables in algebra to represent an unknown number. Variables can also help you solve some questions faster. The format should look like this - Start + Change (Variable) =
The variable can be changed (the one in brackets) while you are trying to solve for unknown.

Question #3 Solve for N

Question #4 Solve the following equations. shaw all of the steps that are needed.

Question 1) What is the difference between an algebraic expression and an equation (hint: One contains this and the other doesn't)? Give an example of both an expression and an equation.

- Algebraic Expression - An algebraic expression is made up of the signs and symbols of algebra. These symbols include the Arabic numerals, literal numbers, the signs of operation, and so forth. Such an expression represents one number or one quantity.

- Equation - An equation states that one expression is equal to another expression or when the value of the variable is given.

the difference between an algebraic expression and an equation is that an algebraic expression does not the variable is not given and that you are able to choose your own variable. in an equation the variable is shown and given.

Question 2) What is a variable and why do we use one in algebra?

- a variable represents an unknown quantity that is trying to be solved for.
- we use variables in algebra because to solve for unknown numbers.
Question 3) Solve for N

the two squares equal two circles and one circle equals one. we dont know the value for the triangle so that's what we're trying to solve for. for first diagram you subtract 4 which is the value of the two squares together from 9 which is the value of the circles together.

4 - 9 = 5

triangle equals 5

Next step since we know now the a triangle equals 5. we add 12 which is the value of the 5 squares together and 10 which is the value of the 2 triangles together.

12 + 10 = 22

Now we divide 22 which is the value of the right and divide it by 2 because of the 2 N's on the other side.

22/2 = 11

N=11

4) Solve the following equations. Show all of the steps that are needed.

a) 3n + 4n + 7 = 2n + 12

7n + 7 = 2n + 12
7n - 2n + 7 = 2n - 2n + 12
5n + 7 = 12
5n + 7 - 7 = 12 - 7
5n = 5
5n/5 = 5/5
n = 1

b) 8n - (4+9) = 11
8n - 13 = 11
8n - 13 + 13 = 11 + 13
8n = 24
8n/8 = 24/8
1n = 3
n = 3

c) (8 - 3)n + 7n + 8 = 4n + 40
5n + 7n + 8 = 4n + 40
5n + 7n + 8 - 8 = 4n + 40 - 8
12n = 4n + 32
12n = 36n
12n/12 = 36/12
n = 3

Question 5) For this question you need to create a T-chart and a graph to plot your data for this question onto.

You are having a race against your friend, except you are on foot and he is on his bike. You both know that is you are on a bike you will be faster so your friend gives you a head start of 3 minutes. If you can run 400m per minute, and your friend can 700m per minute, who will be the first to make it to the finish line 2000m away?

You win because your friend ends up finishing after 6 minutes.

Question 1.) Formulas. We've learned how to write algebraic equations in the form of mx+b=y. Convert these two sentences into algebraic equations using the above formula.

Sentence 1: Scott is 2 years older than Donald who turns 12 in June 21st 2006. Write this sentence in the format of mx+b=y, then convert it into an expression which allows us to figure out the age of Scott.

mx+b=y
12+2=y
14=y

Sentence 2: Elizabeth has $200 in her savings acount. She makes $40 every two weeks babysitting for her next door neighbors. If Elizabeth saves all of her money solve for how moch money she will have in one year.

mx+b=y
200+40=y
240=y

Quaestion 2.) You need to create two questions for your classmates that cover different concepts (ex: T-Charts, patterns, equations, graphs etc.) that you have learned in this unit on Algebra. You need to show how to solve the questions. Your mark will be based upon the level of question's difficulty, and the effort put into your answer.

Question: Carlotta spent $35 at the market. This was seven dollars less than three times what she spent at the bookstore. How much did she spend there?
Let x answer the question-----How much did she spend there?

Answer:
3x − 7 = 35
3x=35+7
3x/3=42/3
x=14

Question: Judy starts working at MacDonald in 24 hours. Every one hour, she receives $10.75. How much money did she collect in 10 hours?

Answer:

Question 3.) 3. Reflection. You need to look back at the chart that we filled out during the first day of the unit. You now need to pick one concept that you coloured yellow or red and reflect in words what new skill that you learned on this topic.

I choose Can I use my words to create an algebraic formula? because I learned this so fast.

This is my example: (actually I have 3 examples.)

1.) 8n-3n+n=12+6------> eight multiplied by a number subtracted by three multiplied by a number added by a number is equal to twelve added by six.

2.) 11-4-2+3n=8n------> eleven subtrcted by four subtracted by two added by three multiplied by a number is equal to 8 multiplied by a number.

3.) 10+4n=14+2n------> ten added by four multiplied by a number is equal to fourteen added by two multiplied by a number.

Question 4.) Preparing for the final exam. You need to think about the year that has past in mathematics and decide which topic is your weakest, and what you need to learn during class review in order to prepare yourself for the final exam. It is not enough to say fractions, instead pick your weakest area of fractions, say the subtraction of fractions, and give an example of what you don’t understand.

Question #1
What is the difference between an algebraic expression and an equation (hint:One contains this and the other doesn't)? Give an example of both an expression and an equation.

An algebraic expression is an expression when you could choose the value of the variable. For Example: 7+3N=. (Instead of N you could put 4 for example) 7+3x4. Like this: 7+3x4=
7+12=19

An algebraic equation is an equation when the value of the variable is given to you. For example: 7+3N= 16 N= 3 . Because if you multiply 3 by3 it givese 9 and add 7 it gives 16.
Solution:
7+3N= 16
7+3x3+16
7+9=16

The difference between them is about their variable. The algebraic equation gives the value of the variable but the algebraic expression lets you choose the value of the variable.

Question #2
What is a variable and why do we use one in algebra?

A variable is a symbol or a letter used to represent any number. We use variables in algebra to represent an unknown number. It doesn't matter if we know its value or not, still variables can help you solve things faster. In an algebraic expression, a variable is the number you can change the value. It should look like this : START+ CHANGE(VARIABLE)=. The one on the brackets you could change. In an algebraic equation, a variable is the number you need to find out. For example: 4+ 2N= 8 N= 2 .

Question #3
Solve for N

On the diagram above, I showed how I got 5 as the value of the triangle. If you look on the right side of the scale, You see 9 blue circles and each blue circles is worth 1 so the total value of the circles is 9 or 9 circles. On the left side of the scale you see 2 pink squares, each squares is worth 2 or 2 circles so the total value of the 2 squares is 4 or 4 circles. On the left side of the scale there's a triangle too. To get the value of the triangle you subtract the total value of the 2 squares from the total value of the 9 circles. Like this: 9 - 4 = 5. So the value of the triangle is 5 or 5 circles.

On the diagram above, I showed how I got the value of the N. I f yoou look on the right side of the scale. You see 6 squares and as we learned from the last diagram each square is worth 2 or 2 circles so the total value of the 6 squares is 12 (6 x 2). On the right side of the scale there's also 2 triangles and as wew learned from the last diagram each triangle is worth 5 or 5 circles so the total value of the 2 triangles is 10(5 + 5). To get the value of the 2 pink circles with the N inside on the left side of the scale, first you have to find out the total value of all the shapes on the right side of the scale. Like this: 10 ( total value of the 2 triangles) plus 12 ( total value of the 6 squares). 10 + 12 = 22. As you can see on the left side of the scale there are 2 pink circles with N inside. So you have to divide the total value of all the shapes from the right side of the square by 2. Like this : 22 / 2 = 11. N = 11

Question # 4
Solve the following equations. Show all of the steps that are needed.

a) 3n + 4n + 7 = 2n + 12
7n + 7 = 2n + 12
7n - 2n + 7 = 2n + 12 - 2n
5n + 7 = 12 5n + 7 - 7 = 12 - 7
5n = 5
5n /5 = 5 / 5
n = 1

b) 8n - ( 4 + 9 ) = 11
8n - 13 = 11
8n - 13 + 13 = 11 + 13
8n = 24
8n / 8 = 24 / 8
n = 3

c) (8 - 3) n + 7n + 8 = 4n + 40
5n + 7n + 8 = 4n + 40
12n + 8 = 4n + 40
12n - 4n + 8 = 4n + 40 - 4n
8n + 8 = 40
8n + 8 - 8 = 40 - 8
8n = 32
8n / 8 = 32 / 8
n = 4

Question #5
For this question you need to create a T-Chart and a graph to plot your data from this question onto.

You are having a race against your friend, except you are on foot and he is on his bike. You both know that if you are in your bike you will be faster so your friend gives you a head start of 3 minute.

1.) Question # 1 :
What is the difference between an algebraic expression and an equation (hint: One contains this and the other doesn't)? Give an example of both an expression and an equation.

** An algebraic expression has no value until the variables in the epression have been replaced with numbers. To evaluate an expression, replace every variable with a given value for the variable, then evaluate the resulting numerical expression.

** An equation states that one expression is equal to another expression

The difference between an algebraic expression and an equation is that for algebraic expression the variable is not given. You can choose your own variable. In an equation the variable is determined.

** Example
Algebraic Expression

30 + 18 (m)
30 + 18 (12)
30 + 126 = 246

Equation

2n = 10
2n/2 = 10/2
n=5

Question # 2 :
What is a variable and why do we use one in algebra?

** A variable represents the unknown quantity. We use it in algebra because that's what we're solving for.

Question # 3 :
Solve for N

If a square equals two circles and a circle equals one then for the first diagram you have to subtract 4 - 9 to know what a triangle equals to.

4-9=5

a triangle equals to five

Now that we know that a triangle equals to five then we'll be able to solve the next diagram

we add 12 + 5 + 5

12 = 6 squares

5 = 1 triangle

you add that all up and you get 22 and then you divide 22 by 2 because there are two n's on the other side and you get 11 as an answer. So n=11

Question # 4 :

Solve the following equations. Show all of the steps that are needed.

a.) 3n + 4n + 7 = 2n + 12

7n + 7 = 2n + 12

7n - 2n + 7 = 2n - 2n + 12

5n + 7 = 12

5n + 7 - 7 = 12 - 7

5n = 5

5n/5=5/5

n=1

b.) 8n - (4 + 9) = 11

8n - (4 + 9) = 11
8n - 13 = 11
8n - 13 + 13 = 11 + 13
8n = 24
8n/8 = 24/8
1n = 3
n = 3

c.) (8 - 3)n + 7n + 8 = 4n + 40

5n + 7n + 8 = 4n + 40
5n + 7n + 8 - 8 = 4n + 40 - 40
5n + 7n = 4n
12n = 4n
12 = 4n
12/4 = 4n/4
3 = n

Question # 5 : For this question you need to create a T-chart and a graph to plot your data from this question onto.

You are having a race against your friend, except you are on foot and he is on his bike. You both know that if you are on a bike you will be faster so your friend gives you a head start of 3 minute. If you can run 400m per minute, and your friend can bike 700m per minute, who will be the first to make it to the finish line 2000m away?

you won the race.

Question # 1 : What is the difference between an algebraic expression and an equation (hint: One contains this and the other doesn't)? Give an example of both an expression and an equation.

In Algebra Expression is when the variable is a number and given and in Algebra Equation, the variable is given as a letter. It's when you try to solve for the variable.

Example:

Algebraic Expression
8 + 2 (3)
8 + 6 = 14
Equation
8 + 2(a)
8 + 2(3)
8 + 6 = 14

Question # 2 : What is a variable and why do we use one in algebra?

A variable is an unknown quantity that we are trying to solve for. It is also represented by a letter. We use variables so we can find what the letter stands for.

Question # 3 : Solve for N

How to solve this:
- First, you subtract 9 by 4 because the two squares are equal to 4. So you'll get 5 as the answer. So now you know what the triangle is equal to. Now, add 12 and 10 together because there's 5 squares and two triangles. 2 + 2 + 2 + 2 + 2+ 5 + 5 = 22. Last is, divide 22 by 2. 2 because there's two N's. the answer is - 11

Question # 4 : Solve the following equations. Show all of the steps that are needed.

a.) 3. + 4n + 7 = 2n + 12

7n + 7 = 2n + 12

7n - 2n + 7 = 2n - 2n = 12

5n + 7 = 12

5n + 7 - 7 = 12 - 7

5n = 5

5n/5 = 5/5

n = 1

b.) 8n - (4 + 9) = 11

8n - 13 = 11

8n - 13 + 13 = 11 + 13

8n = 24

8n/8 = 24/8

1n = 3

n = 3

c.) (8 - 3)n + 7n + 8 = 4n + 40

5n + 7n + 8 = 4n + 40

5n + 7n + 8 - 8 = 4n + 40 - 40

5n + 7n = 4n

12n = 4n

12 = 4n

12/4 = 4n/4

3 = n

Question # 5 : For this question you need to create a T-chart and a graph to plot your data from this question onto.

1.) What is the difference between an algebraic expression and an equation (hint: One contains this and the other doesn't)? Give an example of both an expression and an equation.
- An algebraic expression has one or more numbers and variables with one of the four basic mathematical functions--->variable, constant, coefficient and mathematical method. An algebraic equation also includes an equal sign. The equal (=) sign is followed by the answer of the equation.

2.) What is a variable and why do we use one in algebra?
- The variables are the letters that represent unknown quantities or numbers They vary so we can substitute a variable for one or more numbers. We use variables so we can find the value of the number.

3.) solve for N

9-4= 5
12+5+5= 22
22/2= 11
N=11
- One circle is equal to 1. All 9 circles are equal to 9. Two squares are equal to 4 . One trianlge is equal to 5 so 9-4= 5.
- 6 squares are equal to 12 so 12 + 5 + 5= 22
- 22 divided by 2 is 11, then N is equal to 11

4.) Solve the following equations. Show all of the steps that are needed.

a.) 3n+4n+7=2n+12

7n+7= 2n+12
7n-2n+7=2n+12-2n
5n+7-7=12-7
5n+7-7=12-7
5n/5= 5/5
n=1

b.) 8n-(4+9)=11

8n-13=11
8n-13+13=11+13
8n=24
8n/8=24/8
n=3

c.) (8-3)n+7n+8=4n+40

5n + 7n + 8 = 4n = 40
12n+ 8 = 4n + 40
12n - 4 + 8 = 4n + 40 - 4
8n + 8 = 40
8n + 8 - 8 = 40 - 8
8n = 32
8n / 8 = 32 / 8
8n / 8 = 4
32 / 8= 4
n = 4

1.What is the difference between an algebraic expression and an equation ?
A algebraic expression is made up of lots of signs and symbols from algebra and the symbols have Arabic numerals, literal numbers, the signs of operation. It also represents a quantity.A equation is a mathematical statement meaning it uses math. But in symbols those are two things that are the same. But equations state the equality of two expressions.

A example of a equation is (x + 1)2 = x2 + 2x + 1And a another example for a algebraic expression is 8+10=18I think the difference between a algebraic expression and an equation is that a equation doesnt have signs just symbols and a algebriac expression has both signs and symbols.

2. What is a variable and why do we use one in algebra?A variable is a letter that represents a number that were trying to firgure out so we dont know what that variable is yet.

3.) solve for N.first picture. 2+2+5=9

------Questions for May 30th------

1. What is the difference between an algebraic expression and an equation? Give an example of both expression and an equation.

Both of algebraic equation and expression has all variable, constant ( starting point ), and coefficient ( change ). What varies is the variable. The letter of the variable doesn't matter. What matter is that does the variable in an algebraic equation or expression given. In an expression the variable could be something you choose. In an equation the value of the variable is already given to balance each side of the equal sign.

example :

5x + 5 = money

The expression above has coefficient ( first 5 ), variable ( x ), and constant ( last 5 ). In this expression the variable represent the amount of months.

5x + 5 = money

5(1) + 5 = money

5 + 5 = money

10 = money

Now here an example of an equation. Remember that the variable has already a value.

5n = 5

5n/5 = 5/5

1n = 1

n = 1

2. What is a variable and why do we use one in algebra?

Variables are any letter ( a - z ) that represent numbers. They differ so you can represent it with any number instead. In an algebraic equation you are solving what the variable represent. It already had a value in an equation. In an expression you choose what the variable represent like the example in question 1.

3. Solve for N

Circle ( c ) = 1

Square ( s ) = 2c = 2

In the first diagram, the right side has 9 c or 9. The left side has 2 s and a triangle ( t ). 2s is equal to 4.

9 - 4 = 5

Triangle ( t ) = 5

In the second diagram, the right side has 6s or 12 and 2t or 10.

12 + 10 = 22

There are 2n in the other side. So 2n = 22.

2n/2 = 22/2

1n = 11

n = 11

4. Solve the following equations. Show all of the steps that are needed.

a.) 3n + 4n + 7 = 2n + 12

3n + 4n + 7 = 2n + 12
7n + 7 = 2n + 12
7n - 2n + 7 = 2n - 2n + 12
5n + 7 = 12
5n + 7 - 7 = 12 - 7
5n = 5
5n/5 = 5/5
n = 1

b.) 8n - ( 4 + 9 ) =11

8n - (4 + 9) = 11

8n - 13 = 11

8n - 13 + 13 = 11 + 13

8n = 24

8n/8 = 24/8

1n = 3

n = 3

c.) ( 8 - 3 )n + 7 n + 8 = 4n + 40

(8 - 3 )n + 7n + 8 = 4n + 40

5n + 7n + 8 = 4n + 40

12n + 8 = 4n + 40

12n - 4n + 8 = 4n - 4n + 40

8n + 8 = 40

8n + 8 - 8 = 40 - 8

8n = 32

8n/8 = 32n/8

n = 4

5. For this question you need to create a T-Chart and a graph to plot your data from this question onto.

You are having a race against your friend, except you are on foot and he is on his bike. You both know that if you are in your bike you will be faster so your friend gives you a head start of 3 minute. If you can run 400m per minute, and your friend can bike 700m per minute, who will be the first to make it to the finish line 2000m away?

t-chart :

graph :

you got to the finished line in 5 minutes while your friend got there in about 6 minutes. That means you won the race even though you run.

1. Rotational symmetry is symmetry with respect to some or all rotations in m-dimensional Euclidean space. Rotations are direct isometries, i.e., isometries preserving orientation. Therefore a symmetry group of rotational symmetry is a subgroup of E⁺(m) (see Euclidean group). An object or figure which is indistinguishable from its transformed image is called mirror symmetric

------Questions for May 23rd------

1. Solve all 3 parts of the problem below

Jack collects baseball cards. Jack has 180 baseball cards in his collection. At the end of each month Jack buys 25 baseball cards to add to his collection.

a)Create a T-Chart showing how many baseball cards Jack has at the end of the next 4 months.

b)Create an algebraic formula based upon the problem above

For this problem the starting point is 180, the change is +25, and the variable ( n ) is the number of months.

180 + 25n = the number of cards

c)If Jack just turned 8 years old this month and Jack continues to buy the same amount of baseball cards each month, how many baseball cards will jack have when he turns 12?

180 + 25n =
180 + 25(48) =
180 + 1200 = 1380

When he turn 12 years old he would have 1 380 baseball cards.

2. Use the chart to figure out the questions below.

Jackie is planning on having a pizza party with some of her friends. She is trying to figure out how many pizzas to order. She knows that each pizza has six slices of pizza.

a)If Jackie thinks that there will be four people at the party (counting herself) how many pizzas should she order?

According to the graph, 4 people at Jackie's party ( counting her ) will eat a total of 12 slices of pizza. There are 6 slices in a whole pizza. So, 12/6 = 2 . Jackie will need to order 2 whole pizzas.

b)If two more people show up at the party how many more pizzaÂs does she need to order?

2 more people is 6. 6 people at Jackie's party ( counting her ) will eat a total of 18 slices of pizza. 18 slices of pizza divided by 6 slices per pizza is equal to 3 whole pizzas ( 18/6 = 3 ).

3. Answer the questions below based upon this information

Kathy has $20 in her savings account. Each month she adds another $15 to her savings account. In order to calculate how much money she will have in one year Kathy has created this algebraic formula: 20 + 15n = Savings amount

a) Calculate how much money Kathy will have in one year

20 is our starting point. +15 is the change of her savings account. Her variable is n. It represent the number of months not the number of years.

20 + 15n =
1 year is 12 months.

So, our n represents 12.
20 + 15(12) =
20 + 180 = 200

$200 = savings account

Kathy will have $200 in her savings account in 1 year.

b) Suppose Kathy counted wrong and she really has $25 in her account instead of $20. Change the algebraic formula to reflect this miscalculation.

Instead of 20 our starting point is now 25 since Kathy has really $25. The rest of the algebraic formula is still right

25 +15n = savings account
So,
25 + 15n = savings account
25 + 15(12) = savings account
25 + 180 = savings account
$205 = savings account

you could just add $5 to the previous answer
200 + 5 = $205

4. Solve the following equations. Show all of the steps that are needed.

We start with working on the equations in the brackets ( ) .

Then, we do the like terms on the same side of the " = " symbol.

Next you combine all the variables ( n ) in one side of the " = " symbol.

By then you have everything you need to know what the variable stand for.

a) 3n + 4n + 7 = 2n + 12

3n + 4n + 7 = 2n + 12

7n + 7 = 2n + 12

7n - 2n + 7 = 2n - 2n + 12

5n + 7 = 12

5n + 7 - 7 = 12 - 7

5n = 5

5n/5 = 5/5

n = 1
b) 8n - (4 + 9) = 11

8n - (4 + 9) = 11
8n - 13 = 11
8n - 13 + 13 = 11 + 13
8n = 24
8n/8 = 24/8
n = 3

c) (8 - 3 )n + 7n + 8 = 4n + 40

(8 - 3 )n + 7n + 8 = 4n + 40
5n + 7n + 8 = 4n + 40
5n + 7n + 8 - 8 = 4n + 40 - 40
5n + 7n = 4n
12n = 4n
12 = 4n
12/4 = 4n/4
3 = n

Question #1: Solve all 3 parts of the problem below

Jack collects baseball cards. Jack has 180 baseball cards in his collection. At the end of each month Jack buys 25 baseball cards to add to his collection.
a) Create a T-Chart showing how many baseball cards Jack has at the end of the next 4 months.

b) Create an algebraic formula based upon the problem above

Formula - 180 + 25n =

"n" is the variable used to represent the cards

c) If jack just turned 8 years old this month and Jack continues to buy the same amount of Baseball cards each month how many baseball cards will Jack have when He turns 12.

180 + 25n =

180 + 25(48) =

180 + 1200 = 1380 baseball cards

180 = how many cards he has

25 = how much it raises by

48 = the 4 years... Jack is 8 years old and he continues to get the same amount of baseball cards each month until he's 12. You subtract 8 from 12 and you get 4. Since a year has 12 months you multiply the 4 years by 12 months and you get 48 months.

Answer : Jack will have 1380 baseball cards when he turns 12.

Question #2: Use the chart to figure out the questions below.

Jackie Is planning on having a pizza party with osme of her friends. She is trying to figure out how many pizza's to order. She knows that each pizza has six slices of pizza.

a) If Jackie thinks that there will be four people at the party (counting herself) how many pizza's should she order?

Since Jackie thinks 4 people will be at the party (including herself). 4 people will have 12 slices of pizza, and 1 pizza has six slices of pizza. So Jackie will have 2 Pizza's. 2 pizza's have 12 slices of pizza all together. There is 12 slices of pizza and 4 people... 12 divided by 4 is 3, so each person will have 3 slices of pizza. Jackie should order 2 pizza's.

b) If two more people show up at the party how many more pizza's does she need to order?

If 2 more people show up, you'll have 6 people. The chart says that 6 people will have 18 slices of pizza. Every pizza has 6 slices of pizza. So you'll need 3 pizza's which will have 18 slices of pizza all together. There's 18 slices of people and 6 people... 18 divided by 6 is 3, so each person will have 3 slices of pizza. Jackie should order 3 pizza's.

Question #1:

Jack collects baseball cards. Jack has 180 baseball cards in his collection. At the end of each month Jack buys 25 baseball cards to add to his collection

a.) Create a t-chart showing how many baseball cards Jack has at the end of the next 4 months.

** At the end of the next 4 months, Jack would have 280 cards.

b.) Create an algebraic formula based upon the problem above.

[!] Formula [!]

180 + 25 (m)
180 + 25 (4)
180 + 100 = 280

Starting point = 180
Change from one step to the rest = 25
Variable = (m) m for month

c.) If Jack just turned 8 years old this month and Jack continues to buy the same amount of baseball cards each month how many baseball cards will Jack have when he turns 12?

[!] Formula [!]

180 + 25 (m)
180 + 25 (48)
180 + 1200 = 1380
** When Jack turns 12 he would have 380 baseball cards.

Question #2

Jackie is planning on having a pizza party with some of her friends. she is trying to figure out how many pizza's to order. She knows that each pizza has six slices

a.) If Jackie thinks that there will be four people at the party (counting herself) how many pizza's should she order?

** Jackie should order 2 boxes of pizza. If there are 6 slices of pizza in a pizza box and 4 people are going to show up (counting herself) there would be 12 slices of pizza. It shows in the chart that 4 people would have 12 slices of pizza.

b.) If two more people show up at the party how many more pizza's does she need to order

** Jackie would need to order 3 boxes of pizza because on the chart it says if there are 6 people who are going to show up you would have 18 slices of pizza. So if you have 18 slices and you know that there are 6 slices in each pizza box then you just divide 18 by six and you'll get 3 as an answer and 3 is how many box you need to order.

Question #3

Kathy has $20 in her savings account. Each month she adds another $ 15 to her savings account. In order to calculate how much money she will have in one year Kathy has created this algebraic fromula : 20 + 15n = savings account

[!] Formula [!]

20 + 15 (n)
20 + 15 (12)
20 + 180 = 200

** At the end of one year Kathy would have $ 200 in her savings account.

b.) Suppose Kathy counted wrong and she really has $25 in her account instead of $20. Change the algebraic formula to reflect this miscalculation.

[!] Formula [!]

25 + 15 (n)
25 + 15 (n)
25 + 180 = 205

** If she miscalculated her account and she has $25 instead of $20 then by the end of one year she would have $ 205.

Today we learned about Solving Equation. We also solved lots of questions too.

Solving Equation.
To solve an equation we must have our "variable by it self". We need to move everyting else to the other side of the "=" sign.

4n = 16 => n = 14

Example Questions(We did about 15 questions but i will going to put 5 of them):

1) n + 3 = 10

n + 3 = 10 change the "+" sign to "-" sign

- 3 - 3

n = 7

2) -8 + n = 2

-8 + n =2 change the "-" sign to "+" sign

+8 +8

n = 10

3) 2n = 8

2n = 8 change the "x" sign to "÷" sign

÷2 ÷2

n = 4

4) n - 8 = 6

n - 8 = 6 change the "-" sign to "+" sign

+ 8 +8

n = 14

5) 3n + 1 = 10

3n + 1 = 10 change the "+" sign to "-" sign

- 1 -1 (If you divide 3n from 10, it will still work but it is an ugly way to do it.

3n = 9 If you divide 3n from 10, you have to work with "FRACTION")

9 ÷ 3 = 3

n = 3

May 23, 2006 ----> Growing Post <----------

Question #1: Solve all 3 parts of the problem below :

Jack collects baseball cards. Jack has 180 baseball cards in his collection. At the end of each month Jack buys 25 baseball cards to add to his collection.

a) Create a T-Chart showing how many baseball cards Jack has at the end of the next 4 months.

**I CIRCLED the number of cards Jack would have after 4 months and I also circled the 4th month.**

b) Create an algebraic formula based upon the problem above.

FORMULA---------> 180+ 25c <---------- FORMULA

**I picked c as the variable to represent cards.**

c) If Jack just turned 8 years old this month and Jack continues to buy the same amount of baseball cards each month, how many baseball cards will jack have when he turns 12?

180+25c= 180+25(48)= 180+1,200=1,380

ANSWER: Jack would have 1,380 baseball cards.

**To get how many moths it would take Jack to be 12 years old, you first have to subtract 8 years from 12 years. So 12-8 = 4 years. Then you multiply 4 years to 12 months. So 12 x 4= 48 months.**

Question #2: Use the chart to figure out the questions below. Jackie is planning on having a pizza party with some of her friends. She is trying to figure out how many pizza’s to order. She knows that each pizza has six slices of pizza.

{I drew this again in paint so that you guys can see it better}

a)If Jackie thinks that there will be four people at the party (counting herself) how many pizza’s should she order?

ANSWER: Jackie will need 2 pizza.

** I got 2 pizza as the answer because the chart shows that 4 people will have 12 slices of pizza and each pizza has 6 slices of pizza. So they need 2 pizza to get 12 slices of pizza. So each of them will have 3 slices of pizza.**

b)If two more people show up at the party how many more pizza’s does she need to order?

ANSWER: Jackie will need 3 pizza.

**I got 3 pizza as the answer because there were 4 people but if 2 more people shows up that makes up to 6 people. The chart shows that 6 people will have 18 slices of pizza and in each pizza there are 6 slices. So they need 3 pizza to get 18 slices of pizza. So each person would get 3 slices of pizza.**

Question #3: Answer the questions below based upon this information:
Kathy has $20 in her savings account. Each month she adds another $15 to her savings account. In order to calculate how much money she will have in one year Kathy has created this algebraic formula: 20 + 15n = Savings amount

a) Calculate how much money Kathy will have in one year

20+15n=
20+15(12)=
20+180= 200

ANSWER: Kathy will have $200 in one year.

** I got 12 in the brackets because there are 12 months in a year.**

b) Suppose Kathy counted wrong and she really has $25 in her account instead of $20. Change the algebraic formula to reflect this miscalculation.
25+15n=Savings amount

**Just for fun I tried to solve how much money she'll have in a year if she has $25 in her savings account. Look below:**
25+15n=
25+15(12)=
25+180=205

ANSWER: She'll have $205 in a year.

» K so first we did "Words and Symbols" from the smartboard.

1. A number increases by 5 = n + 5
2. A number decreases by 7 = n - 4
3. A number divided by 3 = n ÷ 3
4. The sum of 7 and a number = 7 + n
5. A number multiplied by 4 = n x 4
6. 8 subtracted from a number = n - 8
7. A number subtracted by 9 = 9 - n
8. Half of a number = n/2
9. 25 divided by a number = 25 ÷ n
10. 10 decreased by n = 10 - n

» Then, we looked at the homework from May 18 about the parking lot
» After that.. Mr.Reece explained how to do some of the growing post questions on blogger.

» We took down important notes about Algebraic Expression and Equation. If you were'nt there on that day we did this, here's your chance to copy it (:

Expression : In an expression we get to choose the value of the variable
Example - 3 + 4n (START + CHANGE (VARIABLE) =

Equation : In an equation the value of the variable is given.
Example - 3 + 4n = 19

* it's trying to find what "n" stands for.

Steps for Solving Algerbraic Equations

1. Solve all the brackets
(8 - 2) n + 5n = 18 + 2n --> 6n + 5n = 18 + 2n

2. Combine like terms that are on the same side of the "=" symbol.
6n + 5n = 18 + 2n --> 11n = 18 + 2n

3. Combine all variables onto one side of the "=" sign.
Example: 11n = 18 + 2n --> 11n - 2n = 18 + 2n - 2n --> 9n = 18

4. Solve for the given variable
Example: 9n = 18 --> 9n/9 = 18/9 --> n = 2

Thank you!!!
Have a nice day!!!

Question #1.) Solve all 3 parts of the problem below

Jack collects baseball cards. Jack has 180 baseball cards in his collection. At the end of each month Jack buys 25 baseball cards to add to his collection.

a) Create a T-Chart showing how many baseball cards Jack has at the end of the next 4 months.

b)Create an algebraic formula based upon the problem above

n stands for number

180+25n

180+25(4)

180+100=280

280 baseball cards

c)If Jack just turned 8 years old this month and Jack continues to buy the same amount of baseball cards each month, how many baseball cards will jack have when he turns 12?

c stands for cards

180+25c

180+25(48)

180+1,200=1,380

1,380 Baseball cards

Question #2: Use the chart to figure out the questions below.

Jackie is planning on having a pizza party with some of her friends. She is trying to figure out how many pizza’s to order. She knows that each pizza has six slices of pizza.

a)If Jackie thinks that there will be four people at the party (counting herself) how many pizza’s should she order?

Jackie needs to order 2 box of pizza if she have 4 friends that are coming at the party (plus her) beacause if you look at the chart at the top you will see #4 it says 12. Each box has 6 slices. Then devide 12 into 6, it will give you 2 boxes.

b)If two more people show up at the party how many more pizza’s does she need to order?

Jackie needs to order 1 more box of pizza if her two friends will show up at the party because if you look at the chart, you will see #6 and it says 18. Divide 6 into 18, it will give you 3 boxes.

Question #3: Answer the questions below based upon this information

a) Calculate how much money Kathy will have in one year.

Hi my name is Cindy and i'm the scribe for today.
What we did today was mental math for 2 and a half minutes. We learned how to find the range, you subtract the biggest number to the smallest number. We also learned about bar notation, you put a line to the number or numbers that is repeating. Today Mr. Reece handed out our math test corrections and unless you have a redo word on your corrections your marks is what you see in your paper. We also learned 1+2r is the formula for algebra. The R could be any letters but we choose the R. Mr. Reece drew shape 1 with 3 boxes, he drew shape 2 with 5 boxes, he drew shape 3 with 7 boxes and we have to figure out the next 3 shapes. The pattern is you add 2 more boxes to every new shape. So shape 4 is 9, shape 5 is 11, and shape 6 is 13 boxes.

Mr.Reece made 3 shapes. This is what it looked like.

Then after Mr.Reece told us to find out the next 3 shapes of the pattern. Just like this picture right here.

Then after Mr.Reece told us to make a T-Chart.

After that Mr.Reece told us to write this formula.

Creat an Algebraic Formula
An Algebraic Formula for any changing pattern needs the following components.

1- Starting Point
2-Changing from one step to the next
3- A variable that represents any posible step in our pattern.

x + 7 =10
The X is the variable.

Then Mr.Reece told us to write this in our notebook.

Start + Change (variable) = ??

After that Mr.Reece tought us how to find the answer for this question.
1 + 2r =
Then on the T-chart we made earlier, Mr.Reece told us to pick a step. For me I picked Step 3.
After you pick the step it would be (R) and that is the variable.
Next Mr.Reece told us to do this:
Multiply 2 by r (3) which gives you 6
After you add the 1 + 6 = 7.
7 is the answer.

This is all we did in class today.

Today at the beginning of class we did, " Mental Math," then quickly after that we learned some more things on our Algebra Unit.

In Mental Math we had some simple questions like:

42.0 x 100 = 4200.0
2 quarters = 10 nickels
? /100 = 0.2 ( ? = 20 because 100 x 0.2 = 20 )
If a girl is going to be a teenager in 5 years, how old is she now? 8 years old

and others.

Then we wrote down a meaning for one of the most important words in algebra.

Variable - a number in an expression which will change

Then Mr. Reece gave us two problems to do where we needed to use a variable to solve the problem. We also needed to make up our own Algebraic expression.

Problem #1
A blizzard has started in Winnipeg. It has already snowed 5cm. It is snowing 2 new centimetres each hour. How much snow has fallen at the end of 8 hours?

5 + 2a

5 + 2(8) (2 x 8=16)

5 + 16= 21 cm

The "a" is the variable in this case and is changed to the 8 because it is our missing quantity. Then you multiply 2 x 8 which is 16 and add it to the start which is 5 and you get 21 cm.

Problem #2
You have already scored 20 baskets and you will score 5 new baskets each game you play. If you still have 15 games to play this year how many baskets will you have in total?

20 + 5b

20 + 5(15) ( 5 x 15=75)

20 + 75=95 baskets

The "b" is our variable and is changed to 15 because its our missing quantity. Again you multiply 5 x 15 = 75 and add it to the start 20 and you get 95 baskets.

Then Mr. Reece told us to do the same question but instead of playing 15 games they're going to play 20 games.

20 + 5b

20 + 5(20) (5 x 20=120)

20 + 100=120 baskets ("same process")

After that Mr. Reece gave us a worksheet which is on Algebraic Expressions and we have to solve them and put the letters in the matching boxes to make a word at the end.

This worksheet was for homework and is due: may 18/06

THE NEXT SCRIBE WILL BE

1.) What is meant by the terms "Rotation Symmetry" and "Reflection Symmetry"? How does this relate to pentominoes? Explain these terms so that anyone who reads your post understands what you mean.

Rotation Symmetry is when a figure can be rotated so that it fits exactly onto its outline more than once in a complete turn, it has rotational symmetry.
Reflection Symmetry is if a figure or object looks the same after being reflected in a mirror, then it has reflectional symmetry. The line where you must put the mirror for this to work is called the line of symmetry (or in 3D, the plane of symmetry).

2.) Create a pattern. You must represent this pattern both pictorially (i.e. with a picture or diagram) and with numbers. You must show the first 4 steps of your pattern.

Shape #1

Shape #2

Shape #3

Shape #4

3.) Describe in words what is occuring with your pattern and if your pattern has an ending or if it continues on indefinately. Make sure that your explanation is clear enough that the person reading your description could understand your pattern without seeing your diagram.

My shape is a small letter L . First I started at two squares then the next shape becomes longer by adding one square at the bottom. You'll just do it again and again.

4.) Create a T-Chart that shows what is happening with your pattern. You must show the first 4 steps of your pattern with the T-chart.

Question #1: What is meant by the terms "Rotation Symmetry" and "Reflection Symmetry"? How does this relate to pentominoes? Explain these terms so that anyone who reads your post understands what you mean.

A Reflection Symmetry means when the axis of symmetry of a two-dimensional figure is a line such that, if a perpendicular is constructed, any two points lying on the perpendicular at equal distances from the axis of symmetry are identical

A Rotation Symmetry is symmetry with respect to rotations, like isometries that preserve orientation. For instance, you can take any point on any shape, and rotate on the point, and it'll still be the same shape, thus preserving the orientation.

These two terms relate to pentominoes because you can rotate(like in rotational symmetry) and flip (like in refectional symmetry) .

Question #2: Create a pattern. You must represent this pattern both pictorially (i.e. with a picture or diagram) and with numbers. You must show the first 4 steps of your pattern.

My pattern Starts off with three squares and keeps adding one square each time.

Question #4: Create a T-Chart that shows what is happening with your pattern. You must show the first 4 steps of your pattern with the T-chart.

Question #1: What is meant by the terms "Rotation Symmetry" and "Reflection Symmetry"? How does this relate to pentominoes? Explain these terms so that anyone who reads your post understands what you mean.

Rotation summetry is a symmetry that is about some or all rotations so it is about a figure or an object that can be rotated on its axis . Like the picture below, the 2nd shape looks different on that angle but if you rotate it in 180 degrees, it is going to look like the first shape and that's how rotation symmetry works. Two objects might look different in a different angle but if you try to rotate one object, then it will look like the other object. Here is an example of Rotation symmetry.

Reflection symmetry is a symmetry with respect to reflection so it is about a figure or object that is flipped or reflected like a mirror. Like in the shapes below, shape 1 is the original one and shape 2 is just a reflection because if you flip it vertically it will look like shape 1. That's how Reflection symmetry works forexample :Two shapes might look different in a different angle but if you try to flip one object, then it will look like the other object. Here is an example of Reflection symmetry:

A pentomino is a polyomino composed of five congruent squares, connected orthogonally (which means perpendicularly) and it the squares has to be side by side not just the corner touching another square. We also learned that you could make up 12 different pentominoes and it has to be unique which means you can't rotate or flip your original pentomino to make a new one. Here are the 12 different pentominoes:

Rotation symmetry and Reflection symmetry relate to pentominoes because anyway you rotate or reflect a pentomino, it will not turn it into a unique pentomino if it looks the same as another pentomino.

Question #2: Create a pattern. You must represent this pattern both pictorially (i.e. with a picture or diagram) and with numbers. You must show the first 4 steps of your pattern.

Question #3: Describe in words what is occuring with your pattern and if your pattern has an ending or if it continues on indefinately. Make sure that your explanation is clear enough that the person reading your description could understand your pattern without seeing your diagram.

The shape obove is shaped like a capital e. It looks like this: E , but bigger. In Shape 1, the top part of the letter E has 3 boxes shaded in. The middle part of the letter E has 2 boxes shaded in. The lower part of the E has 3 boxes shadedd in. The pattern goes like this: You shade one more box to the top part, one more to the middle part and one more to the lower part for every new shape of the letter E. Remember you shade the box next to the last box on the top part, middle part and lower part and not below it. Also remember in shape 1, the vertical line has 5 boxes shaded in but on the pattern you don't shade another box to that vertical line only to the top part , middle part and lower part of the E. On Shape 2, 3 and 4, I colored the boxes green. Those are the boxes you add to every new shape. This pattern can even continue on indefinately.

Question #4: Create a T-Chart that shows what is happening with your pattern. You must show the first 4 steps of your pattern with the T-chart.

Question #1: What is meant by the terms "Rotation Symmetry" and "Reflection Symmetry"? How does this relate to pentominoes? Explain these terms so that anyone who reads your post understands what you mean.

a) A Rotation Symmetry is when a figure can be rotated so that it fits exactly onto its outline more than once in a complete turn, it has rotational symmetry.

b) A Reflection Symmetry is if a figure or object looks the same after being reflected in a mirror, then it has reflectional symmetry. The line where you must put the mirror for this to work is called the line of symmetry (or in 3D, the plane of symmetry).

c) Reflection and Rotation Symmetry relates to pentominoes because its a 2 dimensional figure and if you rotate it0 doesn't make a difference.

Question #2: Create a pattern. You must represent this pattern both pictorially (i.e. with a picture or diagram) and with numbers. You must show the first 4 steps of your pattern.

Shape #1

Shape #2

Shape# 3

Shape# 4

Question #3: Describe in words what is occuring with your pattern and if your pattern has an ending or if it continues on indefinately. Make sure that your explanation is clear enough that the person reading your description could understand your pattern without seeing your diagram.

a) The pattern is each shape gets bigger by adding one more shape to each end.
b) At first the number of the tiles start at 10 but it keeps but it keeps getting bigger by adding 2 more shapes. (one at each side)
c) The letter is the letter A.

Question #4: Create a T-Chart that shows what is happening with your pattern. You must show the first 4 steps of your pattern with the T-chart.

(1) What is meant by the terms " rotation symmetry" and "reflection symmetry?" How does this relate to pentominoes? Explain these terms so that anyone who reads your post understands what you mean.

a)-Rotation symmetry is when you can rotat (or turn) a figure around a center point by fewer than 360 degrees and the figure appears to seem like it didn't change. The point around which you rotate is called the center of rotation, and the smallest angle you need to turn is called the angle of rotation.

b)-Reflection of symmetry is if a figure or object looks the same after being reflected in a mirror then it has reflection symmetry. The line where you must put the mirror for this to work is called the line of symmetry. In 3D it would be called the plane of symmetry.

c)-Pentominoes are shapes that are formed with 5 squares. The corners have to be touching on it's sides on the top and on the bottom. They can't be touching corner to corner. You can only form 12 unique pentominoes. The picture below show's all 12 unique pentominoes.

-Pentominoes relate to ratation symmetry and reflection symmetry because no matter which way you rotate or reflect the pentomino, the pentomino will not become a unique pentomino.

(2)Create a pattern. You must represent this pattern both pictorially (i.e With a picture or diagram) and with numbers. You must show the first 4 steps of your pattern.

(3)Describe in words what is occuring with you pattern and if your pattern has an ending or if it continues on indefinately.Makesure that your explaination is clear enough that the person reading your description could understand your pattern without seeing your diagram.

- the shape is the letter "E". First it started off with 5 blocks verticle 3 blocks at the top horizontal, 2 blocks in the middle going horizontal and 3 blocks at the bottom also going horizontal. And that makes the "E". The "E" increases in blocks and gets bigger as you add blocks. All the blocks going horizontal (which are the top, middle and bottom line of blocks) increase and the one line of blocks or squares or cubes or what ever you want to call it, going verticle does not increase at all. You add one block or square each to the end of the top line of squares going horizontal and the middle line of squares going horizontal and the bottom line of squares also going horizontal. keep adding squares or cubes to those ends to continue the pattern.

(4)Create a T-Chart that shows what is happening with your pattern. You must show the first 4 steps with the T-Chart.

#1. What is meant by the terms "rotation symmetry" and "reflection symmetry?" How does this relate to pentominoes? Explain these terms so that anyone who reads your post understands what you mean.

- Rotation symmetry is a figure or object that can be rotated on its axis for more than one rotation and the figure or object is still the same.
- Reflection symmetry is a figure or object that is flipped or reflected like a mirror, but the reflected object is not unique.
- Pentominoes are shapes that are formed with 5 squares, and the corners can't just touch corner to corner it has to go beside, on top or under, the picture on top has 12 unique pentominoes.
- Pentominoes relate to rotation and reflection symmetry because anyway you rotate or reflect the pentomino, it will not turn it into a unique pentomino.

#2. Create a pattern. You must represent this pattern both pictorially (i.e. with a picture or diagram) and with numbers. You must show the first 4 steps of your pattern.

#3. Describe in words what is occuring with your pattern and if your pattern has an ending or if it continues on indefinately. Make sure that your explaination is clear enough that the person reading your description could understand your pattern without seeing your diagram.

-This shape is the letter "U". It first starts off as 3 blocks going up and 3 blocks going across the bottom to complete the "U", but in this pattern, the horizontal blocks don't increase, only the vertical blocks. As you continue on with the pattern, you add 1 block each to the top of the you, then the shape has 4 blocks going up and 3 going across at the bottom. The next one will have 5 blocks going up and 3 blocks going across the bottom. You can continue this pattern forever but the "U" would sooooo tall yet so skinny, but it's still a "U".

#4. Create a T-Chart that shows what is happening with your Pattern. You must show the first 4 steps of your pattern with the T-Chart.

This shape is like the letter P. It starts as 3 vertical tiles and 2 more vertical tiles to the right of that. As you go on you add one tile to the bottom of the longer vertical part of the P and add 2 more to the side of the part the only has 2, and so on for the next three shapes. This pattern can continue on and on but wouldn't look much like a P after 6th or 7th shape.

Hi Mr. Reece!!! Please check my growing post again, because I put some changes on it. You can easily see it because I put my changes into a colour Red.

Thanks Mr. Reece!!
Have a nice day :)

1.) What is meant by the terms "Rotation Symmetry" and "Reflection Symmetry"? How does this relate to pentominoes? Explain these terms so that anyone who reads your post understands what you mean.

Rotation Symmetry is a figure around a center of fewer than 360 degrees and the figure appears unchanged. If you rotate or flip a pentominoe, it is still the same shape as the other one.
Reflection Symmetry ( sometimes called Line Symmetry or Mirror Symmetry) is easy to recognize, because one half is the reflection of the other half.These relate to pentominoes because it starts in 5 squares.

2.) Create a pattern. You must represent this pattern both pictorially (i.e. with a picture or diagram) and with numbers. You must show the first 4 steps of your pattern.

Shape #1

Shape # 2

Shape # 3

Shape #4

3.) Describe in words what is occuring with your pattern and if your pattern has an ending or if it continues on indefinately. Make sure that your explanation is clear enough that the person reading your description could understand your pattern without seeing your diagram.

My shape is a letter L. My first shape has 5 squares. You keep adding 1 square at the top and 1 square on the bottom right every step. So if you add 1 square at the top and 1 square on the bottom, the letter will be longer and higher. You can do it again and again in every step (like forever).

4.) Create a T-Chart that shows what is happening with your pattern. You must show the first 4 steps of your pattern with the T-chart.

Question #1: What is meant by the terms "Rotation Symmetry" and "Reflection Symmetry"? How does this relate to pentominoes? Explain these terms so that anyone who reads your post understands what you mean.

rotation symmetry- If you rotate a figure around it is just identical so it doesn't make the shape or pentomino unique.
reflection symmetry- a shape is symmetrical if both sides are the same when a mirror line is draw.

How rotation symmetry relates to pentominoes:
Rotating the pentomino makes it identical and it makes the pentomino not unique. No matter how you rotate the shape, the size and the shape will not change.

How reflection symmetry relates to pentominoes:
It makes a mirror image of the pentomino so the pentomino doesn't make it unique. The shape only flipped so it is still the same shape.

Question #2: Create a pattern. You must represent this pattern both pictorially (i.e. with a picture or diagram) and with numbers. You must show the first 4 steps of your pattern.

STEP 1___ STEP 2

STEP 3_____- _STEP 4

Question #3: Describe in words what is occuring with your pattern and if your pattern has an ending or if it continues on indefinately. Make sure that your explanation is clear enough that the person reading your description could understand your pattern without seeing your diagram.

- The first shape was a capital E. For the first shape, the top of the capital letter E has three tiles, the middle of the letter E has 2 tiles. The bottom of the letter E has 3 tiles.
- If you add one more tiles to the top, middle, and at bottom of the letter E you'll have another shape but you are just changing the size. You add the tiles horizontally.
- For the next three shape. Just do the same thing, the only difference that it will make is the size. The shape will be the same but the size will get larger.
-At the end (right) of every horizontal column for the letter E- at the top, middle and bottom row is where you have to add one tile so every shape adds 3 more tiles. My pattern has no ending. It continues on indefinately.

Question #4: Create a T-Chart that shows what is happening with your pattern. You must show the first 4 steps of your pattern with the T-chart.

1.What is meant by the terms "rotation symmetry" and "reflection symmetry?" How does this relate to pentominoes? Explain these terms so that anyone who reads your post understands what you mean.

Rotation symmetry is the process of turning the center of an axis. Reflection symmetry is a two-dimensional figure, so it’s a reflection. Pentominoes are shapes that are formed with 5 squares and the corners don’t touch the squares go beside or on top and under. Pentominoes relate to reflection symmetry because if you look at it pentiminoes are a two-dimensional figure and it can be reflected of a mirror.

2. Create a pattern. You must represent this pattern pictorially (i.e. With a picture or diagram) and with numbers. You must show the first 4 steps of your pattern

Due Monday, May 15th...my birthday. I thought I should do it early so I don't get any unexpected birthday surprises, such as realizing I forgot to do it...Oops.

1. What is meant by the terms "rotation symmetry" and "reflection symmetry?" How does this relate to pentominoes? Explain these terms so that anyone who reads your post understands what you mean.

I don't know how to do this without sounding exactly like Rainer...But then again, I can't deny that he's exactly right. There are in total 12 unique pentominoes, and pentominoes are made up of 5 squares. Rotation symmetry means something to this effect: if you are arranging the blocks and you think you've found a new pentominoe, but then you check and find out that if you rotate it, it's another pentominoe that already exists, surprise! You've found rotation symmetry. It means that if you can rotate a pentominoe to turn it into one of the already existing 12 pentominoes, then the pentominoe is not unique.

Reflection symmetry is pretty close to being the same thing. Except this time, instead of rotating it, you can flip it over to turn into another pentominoe, then it isn't a unique shape.

2. Create a pattern. You must represent this pattern pictorially (i.e. With a picture or diagram) and with numbers. You must show the first 4 steps of your pattern.

My pattern is using an X pentominoe.
SHAPE 1:

SHAPE 2:

SHAPE 3:

SHAPE 4:

#3. Describe in words what is occurring with your pattern and if your pattern has an ending or if it continues indefinitely. Make sure that your explanation is clear enough that the person reading your description could understand your pattern without seeing your diagram.

I chose an X-shape pentominoe for my pattern. It looks like a cross. It starts off with a centre block, and 4 spokes leading out from it, 2 horizontal, and 2 vertical. Each spoke has one block on it. For each step of my pattern, I add one more block to each spoke of the X. I don't think my pattern needs to have an ending unless you want it to. You could probably keep adding blocks onto it until you died. It could continue on indefinitely as long as you wanted it to.

#4. Create a T-chart that shows what is happening with your Pattern. You must show the first 4 steps of your pattern with the T-chart.

------Questions for May 15th------

Rotation symmetry or rotating any shape makes an identical shape of the original shape. Using the method of rotation symmetry to a pentomino will make a different but still similar pentomino. This does not make the new pentomino unique. Because it has a similar pentomino.

Reflection symmetry or flipping any shape makes a mirror image of the original shape. Also, using this method to a pentomino makes the mirror image of the original pentomino. It doesn't make the pentomino unique because it has a very similar image ^_^ .

2. Create a pattern. You must represent this pattern both pictorially ( i.e. with picture or diagram ) and with numbers. You must show the first 4 steps of your pattern.

shape # 1

shape # 2

shape # 3

shape # 4

3. Describe in words what is occurring with your pattern and if your pattern has an ending or if its continues on indefinately.

This shape is like stairs. It started as a 3 blocks by 3 blocks figure ( shape # 1 ). You keep adding the next set of blocks at the bottom and the bottom-right corner of the shape. So if you add the next set of blocks the shape will be longer at the left side and at the bottom side, like what is happening to the next 3 shapes. This pattern continues on and on forever. It adds more and more set of blocks than anyone could imagine.

4. Create a T-chart that shows what is happening with your pattern.

To get shape 6 and shape 8 you must figure out a formula that works for every shape with or without shape 1. I can't figure out the formula so what I did is count. I'll try to figure out the formula but in the mean time I'm done my post.

------Questions for May 23rd------

1. Solve all 3 parts of the problem below

Jack collects baseball cards. Jack has 180 baseball cards in his collection. At the end of each month Jack buys 25 baseball cards to add to his collection.

a)Create a T-Chart showing how many baseball cards Jack has at the end of the next 4 months.

b)Create an algebraic formula based upon the problem above

For this problem the starting point is 180, the change is +25, and the variable ( n ) is the number of months.

180 + 25n = the number of cards

c)If Jack just turned 8 years old this month and Jack continues to buy the same amount of baseball cards each month, how many baseball cards will jack have when he turns 12?

180 + 25n =

180 + 25(48) =

180 + 1200 = 1380

When he turn 12 years old he would have 1 380 baseball cards.

2. Use the chart to figure out the questions below.

Jackie is planning on having a pizza party with some of her friends. She is trying to figure out how many pizzas to order. She knows that each pizza has six slices of pizza.

a)If Jackie thinks that there will be four people at the party (counting herself) how many pizzaÂs should she order?

b)If two more people show up at the party how many more pizzaÂs does she need to order?

2 more people is 6. 6 people at Jackie's party ( counting her ) will eat a total of 18 slices of pizza. 18 slices of pizza divided by 6 slices per pizza is equal to 3 whole pizzas ( 18/6 = 3 ).

3. Answer the questions below based upon this information

a) Calculate how much money Kathy will have in one year

20 is our starting point. +15 is the change of her savings account. Her variable is n It represent the number of months not the number of years.

20 + 15n =

1 year is 12 months. So, our n represents 12.

20 + 15(12) =

20 + 180 = 200

$200 = savings account

Kathy will have $200 in her savings account in 1 year.

b) Suppose Kathy counted wrong and she really has $25 in her account instead of $20. Change the algebraic formula to reflect this miscalculation.

Instead of 20 our starting point is now 25 since Kathy has really $25. The rest of the algebraic formula is still right

25 +15n = savings account

So,

25 + 15n = savings account

25 + 15(12) = savings account

25 + 180 = savings account

$205 = savings account

you could just add $5 to the previous answer

200 + 5 = $205

4. Solve the following equations. Show all of the steps that are needed.

We start with working on the equations in the brackets ( ) .

Then, we do the like terms on the same side of the " = " symbol.

Next you combine all the variables ( n ) in one side of the " = " symbol.

By then you have everything you need to know what the variable stand for.

a) 3n + 4n + 7 = 2n + 12

3n + 4n + 7 = 2n + 12

7n + 7 = 14n

14n = 14n

14n = 14

14n/14 = 14/14

n = 1

b) 8n - (4 + 9) = 11

8n - (4 + 9) = 11

8n - 13 = 11

8n - 13 + 13 = 11 + 13

8n = 24

8n/8 = 24/8

n = 3

c) (8 - 3 )n + 7n + 8 = 4n + 40

(8 - 3 )n + 7n + 8 = 4n + 40

5n + 7n + 8 = 4n + 40

5n + 7n + 8 - 8 = 4n + 40 - 40

5n + 7n = 4n

12n = 4n

12 = 4n

12/4 = 4n/4

3 = n

My name is Rina Yso and I am the scribe for today. Today what we did was we got a paper that had 3 shapes on it.

This is the shape me and my group had:

After that Mr.Reece told us to draw the next 3 patterns of the shape.

After that Mr.Reece told everyone to go with other people who had the same shapes. Then we had to come up with the best explanation for the pattern.

My group's explanation was we had to shade in another square on each end and that our shape was the letter A.

Then Mr.Reece asked one person from each group to come up in front of the class and share their explanation. Then Mr.Reece gave us a T-Chart sheet.

What we had to do for the chart was we had to write the number of the shapes and then we had to count how many tiles we used for each shape.

And that's all we did for today.

The next scribe will be Cindy Jamoyot!

Well, today's class was interesting...Anyway, here's what we did:

We started off going over our coordinate planes from yesterday, the 6 (I think) coordinates we had to put on the grid coordinate plane, during which Mr. Reece helpfully reminded us all that people sleep horizontally, unless they were in space with zero gravity, or some weird kind of bat creature. Mr Reece also reminded us that the Y axis is vertical, and the X axis is horizontal, and that before you start with a coordinate plane, you need to mark them down:

After that, we got new sheets of coordinate plane paper, and he gave us a new assignment.
He gave us coordinates for 4 new shapes, and they all make a shape.
SHAPE #1:
A: Start at (4, -8)
B: Right 6
C: Up 7, left 3.
It makes a triangle:

SHAPE #2:
E. Start at (-11, 13)
F. Down 1, Right 7
G. Down 4, Left 2
H. Up 1, Left 7
It makes a parallelogram:

SHAPE #3:
A. Start at (-10, -1)
B. Down 2, Right 2
C. Down 6, Right 2
D. Up 2, Right 2
E. Down 2, Right 2
F. Down 4, Left 4
G. Up 2, Left 2
H. Up 6, Left 2
I. Down 2, Left 2
J. Up 2, Left 2
K. Up 4, Right 4
It makes a sort of "Z" shaped thing if you tilt your head to the left:

SHAPE #4:
A. Start at (1, 7)
B. Down 3, Right 1
C. Up 1, Left 4
D. Down 2, Left 2
E. Down 3, Right 6
F. Up 2, Right 2
G. Up 3, Left 1
H. Down 1, Right 3
I. Up 2, Right 2
J. Up 6, Left 3
K. Down 2, Left 2
L. Down 4, Right 1
It looks kind of like a W, I don't know if you guys got the same thing, though:

For Homework today, we basically had nothing, I'm not sure whether we needed to finish these 4 shapes or not... anyway, tomorrow's scribe is......

TIMMY!!!! :P

See you later everyone, and I hope the scribe list is accurate.

homework?

2006-04-18T17:58:00.001-07:00

Was there homework today?

Note: There was no homework due for Wednesday or Thursday. (Mr. Reece)

.......

2006-04-18T15:57:00.000-07:00

we have a test next week about circles

I FOUND A SITE!!!!

2006-04-17T18:25:00.000-07:00

HELLO EVERYONE, I found a site. You'll learn how to calculate the circumference of a circle also known as a perimeter of a circle. You'll find out what radius and diameter are and how to find their values. There are links to eThemes resources on perimeter and π. It includes animations, interactive exercises, quizzes, and worksheets.

It talkes about addition, algebra, comparing, counting, decimals, division, equations, estimation, exponents, fractions, geometry, graphs, measurement, mental math, money, multiplication, naming numbers, patterns, percent, place value, practical math, properties, ratios, statistics and subtraction.

This website is for grade 4, 5, 6, 7 and 8. So I hope you guys check it out. It also shows brain pops ,you know. It is like the ones Mr. Reece shows us. It has brain pops for social studies, english, science, health, technology and of course MATH. So if you guys forgot the brain pops Mr. Reece shown us, just go to to this site and lookl for the site about brain pop and you can review it at home.

HAVE FUN EVERYONE!

Scribe List

2006-04-14T06:14:00.000-07:00

I have decided to reset the scribe list. Everyone in the class who wishes to be the scribe for the day will earn the right to post the scribe notes. As well as the scribe posts are not mandatory, you can chose to opt out of the scribe posts. You must inform either myself or the previous scribe with your decision to not conplete the scribe post so that we can chose a new scribe. Remember you earn bonus marks upto the equivalent of two blogger assignments for completing the scribe post.

This is The Scribe List. Every possible scribe in our class is listed here. I will do my best to update this list every day. If you see someone's name crossed off on this list then you CANNOT choose them as the scribe for the next class.

This post is can be quickly accesed from the [Links] list over there on the right hand sidebar. Check here before you choose a scribe for tomorrow's class when it is your turn to do so.

First ting we did in math today is mental math in minute number 13. After that, we learned how to measure the diameter of a circle, radius, circumference and circumference/diameter like the one we did yesterday, but the only thing we did not learn is how to get the circumference/diameter.

How to get the circumference/diameter:
You just need to divide the circumference to the diameter
(this symbol / means divide)
Example:
26 = circumference
8 = diameter
26/8= 3.25 or pi

circumference/diameter gives you pi

Pi is used represent to the ratio of a circumference of a circle to its diameter.

These are some of the formula for those who don't know this yet
diameter/pi= circumference
Example:
11= diameter
3= pi
11/3= 3.6

circumference/pi= diameter
Example:
74= circumference
8.2= pi
74/8.2=9.02439

This is what we learned today. Oh yeah I remember, after we learned how to solve the pi, we saw another episode with Tim amd Mobie and this episode is about how to measure a circle.

And the scribe on Monday is Courtney...... :)

first of all, we finished measuring the rocket from yesterday's class. it is due i think friday so hand it in as soon as possible.

like every math class we had this couple of weeks, we did mental math. today's minute was minute #1. so try to do it if you were late or absent this morning.

so this is what we did today.....

this class should have been a review for some of us. we reviewed another shape that is not a polygon and has no sides a circle.

if your not here this class, here's the notes.....

Elements of a Circle

Elements of a circle includes:

centre
diameter - starts at one edge and ends at the opposite end, and has to pass through the centre
radius - starts at centre and goes to the edge ( to measure - divide the diameter by 2 )
circumference - perimeter of the circle or the measurement all the way around the outside of the circle

in parts of the class we measured different sizes circles. you have to find different measurements to put a table......

here's what it needs to have......

circle # ( label )
radius ( in centimeter )
diameter (in centimeter )
circumference ( in centimeter )
circumference/diameter

for now you dont have to have the circumference/diameter part filled up.... but.... you should have measured 8 different circles by now..... but you still have time tomorrow......

i think i said everything...... tell me if i forget something............

The first thing we did in math today is reviewing yesterday's lesson the Rule for finding the Perimeter of a rectangle and here is the formula: height x width

Then we did Mental Math Minute 3 and here are some of the question:

1.) The product of 4 and 6 is

2.) 2, 463 x 0 =

3.) 1, 10, 2, 9, 3, , , .

Here are the answers:

The product means the answer of two numbers multifly together
1.) 24

Anything that you multifly by zero will be Zero
2.) 0

The pattern is 1 is becoming higher and ten is becoming lower
3.) 8, 4, 7

After that, we did the Finding the Area of a Triangle

Here is the formula: ( height x width ) /2

Then we learned the formula for finding the area of a parallelogram

Here is the formula: heigth x width

And that's all we did today

The scribe tomorrow is James

Shawn's Scribe Notes

2006-04-04T14:02:00.000-07:00

The first thing we did to day in math was our mental because now after almost 3 or more months Mr.Reece decides we should start working on it again, but they are new booklets with rewritten questions in it, so we dont have to right down the questoins the from the board anymore. Well anyways... back to math.

These are some examples of the type of questions we do in mental math:

5x5 or 52 =25

(picture above) which # is in both bubbles answer: 10

10/5 = 2 or reduce it to 2/1 = 2

(order or operation) 10-5x2 = 2

Then today in class we learned a bit more about line segments. Mr.Reece showed us what a line segment looks like on a piece of grid paper, how to count line segments, shapes you can make out of a number of line segments, and also how to determine how many squares can be fitted in a line segment rectangle or square.

In past classes Mr.Reece taught us that a line segment has a starting point and an ending point

After showing us what a line segment looks like and how to count a line segment, we had to make rectangles from a number of line segments Mr.Reece gave to our rows. My specific row had to make up rectangles of 20 line segments.

Then we asked ourselves how many rectangles we can make with the same amount of line segments.

No one really got it but i came up with exactly how many rectangles you can make with a 20 line segments. I got at least 5 different rectangles, but if you include the rectangle when it's turned on the other side of line segments, then I would have 9 not including the one with five sides because it doesnt change either way you turn it.

After we made as many rectangles as we could with the appointed line segments we had, we discussed with our groups to determine how many squares can go inside your rectangle.

Then we found out a theory to determine how many squares can go in your rectangle!! First you take the number of line segments on the veritcle side of your rectangle, then x (times) it by the number of line segments on the top or horizontal side of your rectangle. I find that, that is the easiest way to find out how many squares you have in your rectangle.

Reminders:

- fix corrections on math test on seperate piece of paper and hand it back for extra marks

- study for science test (solutions and whatever...)

- study for french test tomorrow

THE NEXT SCRIBE Will BE....JORELLLLLLLL!!!!!!

The Scribe for today- April 3rd 2006!!!

2006-04-03T18:53:00.000-07:00

Today in math, first thing we did was mental math.

April 03 2006 Mental Math
Examples:
6x3= 18
Three dollars equal 300 pennies.
3-5x6= 27
0, 5, 10, 15, 20, ___, ___, ___. answer: 25, 30, 35
0x1,234= 1,234
3/ 27= 9
The product of two and three is ______. answer: 6
The sum of six and eleven is ______. answer: 17

Then we learned about how to find the find the perimeter of an object.

The rule for finding the perimeter: Add all the sides together.

Finding the perimeter of an object
(To find the solution, read the RULE above^)

answer: 8+15+8+15= 46

Find the perimeter of these objects:

18+18+18+18= 72m
18x4= 72m

42+9+42+9= 102cm

3+4+5=12

Finding the missing measurement

30+8+8=46 76-46=30
The missing measurement is 30mm
How did you get 30mm?
76- total perimeter
Subtract the total to 46
?= 30mm

Total perimeter- 42
8+8+7+7=30
42-30=12
?= 12

Determing Perimeter

What is the perimeter?
answer: 10+10+10+10= 40cm

answer: 25+25+40= 90

answer: 20+10+12+9+5=56

Later on today...we had to create a shape for each given perimeter

A.) 28cm B.)11cm C.)33cm D.) 20cm

a.) 7+7+7+7=28cm
b.) 2+5+4=11

c.) 12+10+11= 33cm
d.) 5+5+5+5=20cm

Four people went up to the board and drew a diagram for each given perimeter (a,b,c and d). Each person had different styles to other people.Some were even creative than the other.

Eight minutes before class was over, Mr. Reece asked a question about a square.
Is a square a rectangle?
We had a little survey. Two people said yes and 2 people said no. Then Mr. Reece had to break the tie, so he asked one more person. That person said yes!
Is it yes or no?
Answer: YES! A square is a rectangle because the opposite sides are equal. It may not have the same size but the sides are all equal.

FOR HOMEWORK!!!
Create a shape for each given perimeter:
a.) 28cm b.)11cm c.)33cm d.) 20cm

*YOU MUST REMEMBER:
You can only draw a shape in minimum of 5 sides!

The next scribe will be...
SHAWN!!!

k as you know i'm the sribe for yesterdaay and todaay .. i am gonna be taalking about stuuff we did yesterdaay first.. so here :

Sribe for March 22`06

First, we reviewed the homework from March 21, 10.6 The Sum of the Angles in a Triangle - Questions 3, 11 and 14

Question # 3 :

To find the missing angle for this triangle, add 120 and 40 together. It'll give you an answer which is 160 . Now, subtract 160 to 180. The ANSWER is 20 degrees .

Question # 11 :

To fiind the size of this exterior angle, you haaave to subtract 73 by 180 . So the ANSWER is 107 .

Question # 14 :

To find the unknown angles for thiis one, add 50 and 70 together. You'll get 120 as the answer, subtract it by 180, so the ANSWER for a is 60 . The ANSWER for b is also 60 degrees too because a and b are opposite . Now, add 53 and 60 together then subtraact the sum to 180. You'll get the ANSWER for c which is 67 .

Then Mr. Reece read the story "The Greedy Triangle" to us . It was about a triaaangle who was unhaapy with hiis shaape. He kept on getting loads of loads of sides. He used the shaape shifter so maany times that he turned in to Quadrilateral, Square, Pentagon, Hexagon and to many more polygons. But then when he turned in to a circle..he decided thaat he's haapy with his originaal shape which is the triangle .

Then after, Mr.Reece gave us the sheet wiith triaangles in it. We haad to cut the shaapes and cut them in to pieces . Using the pieces we haad to find out about other shaapes thaat we could maake .

[!] Remember that a triangle is equal to 180 degrees. It haas 3 sides and 3 angles.

Mr. Reece also told us that we haave to stuudy for the quiz todaay .

++++++++++++++++++++++++++++++++++++++++++

Sribe for Maarch 23`06

Todaay we looked at the blogger and Mr.Reece showed us the maap thing whiich shows people from different countries that visited our math blogger .

This is one of the examples that we did on the smaartboard .
- Which Hexagon has the correct number of triangles ?

The one in the left is right because there's less triangles and you measure it in interior .

After thaat, we reveiwed for the quiz then we waatched a video about angles and triaangles . Then we started the quuiz. (:

THE NEXT SRIBE IS LEVINIAAA (:

REMINDERS FOR TOMORROW MARCH 24`06 .

- TLE Classiying Angles DUE

- Spring Fling Dance ;)

- Basketball Assembly
