Growing Post #3

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.

Scribe List

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.

Jorel's scribe notes

April 5, 2006

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

TLE Due Dates

The TLE lesson Classifying Angles is Due Friday by 12pm. If you have not yet finished this TLE Lesson remember that the computers in my room are open for use before and after school.

The lesson on Angles and Parallel Lines 1 will be due after our next session in the computer lab. (Which should be the week after springbreak.)

Mr. R

This does not include the TLE worksheet, only the computer portion for Angles. My appologies for any confusion

Loss of use

A select individuals have abused the chatbox feature on our blogs. Therefore I have no choice but to at least temporarily remove the chatbox from the blogs. If the individuals responsible for the inappropriate comments come forward and discuss this issue with me I will be able to return the chatbox to your blog.

Unfortunatly I cannot tolorate comments such as those that had been left in the chatbox. Any further comments such as these in class or on the blog will be sent to the administration and your parents will be contacted.

Remember that comments that you leave on a blog now remain on the net in some form forever, therefore what we may percieve as a joke right now, might come back to haunt us in the future.

Mr. Reece

Proper profiles

I am requesting that anyone who has any form of personal information in their user profile to remove it immediatly. If your nickname contains personal information I suggest that you change it as well.

Personal information includes
Last name
Phone number
Picture
Address
Names of brothers/sisters/parents

Any other information that identifies you beyond your screen name or first name.

I do not want to have to remove you as a contributer from the blog, but I will be forced to in order to protect you if you cannot act in a safe manner on the blog.

Mr. R
