Growing Post 4: Due 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.

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.

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.

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 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.

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.

This is our final week of Algebra, we will be starting our review for the final exam next week.


  • Q1-

    Sentence 1)12a + 2 =
    12(1) + 2 = 14
    y = 14
    Sentence 2)200 + (40x52%2) = y
    200 + (1040) = y
    y = 1240


    Maxine talks on her cell phone for at least 30 minutes a day. Each minute is worth 10 cents and Maxine paid $60.00 for her minutes. How many minutes will Maxine have left in a week? Make a chart to show this information then put it on a graph.What kind of expression would you use to find this out?

    Well first you would find out that $1.00 = 10 miutes because it's easier to add. So if $1.00 = 10 mintues and there is 7 days in a week then 7 x $1.00 = $7.00 and $7.00 = 70 minutes. So an equation would be 60 - 30(7) = 150
    SO 150 minutes are left i think.And just make a chart and graph i don't know how to explain that.


    yellow - Can I describe in wrds what is happening with the pattern?

    I learned new ways of describing a shape like it's quantity, shape, size, colour, etc. This will help me for grade 8 i think .


    I will need to study the divisibility test because I totally fogot it, and I know that I will need to know it for the exam.
