chaaarmaaine's growing post # 4

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

The only problem that I can see is that there are a total of 52 weeks in a year and she gets paid every two weeks so you take 52/2 = 26. Otherwise it is a great post with great questions.
Your mark is 24/25
