### Jordan's 2nd Growing Post

1. What strategies were needed?

2. How did you use these strategies?

3. Or How could you of used these strategies.

4. How would you figure out the price of a 6 cup bag of Betty's Snack mix? Use a ratio table

5. Find 3 other values (amounts of Snack Mix) that could be solved using the same ratio table. Find the \$\$ of your new container sizes.

1. My strategy was multiplying

2&3. I used or could of used this strategy by multiplying
2 2/5 by 2, 3, 4... until I got Then multiplying all the ingredients by that number.

4. To figure out the price of a 6 cup bag you take you answer from 12 cups and divide by 2.

5. This is how i figured out 3 different size cups (i used 12 as a starting point)
You are going to create a voicethread explaining the strategies you used on your test. You need to choose 4 out of the 6 questions.
1. 2/3 + 1/4 + 2/5 =
2. 6/5 - 11/10=
3. 3/5 + 2/7 =
4. 1/6/+1/9 =
5. 5/6 - 1/4 =
6. 3 3/5 - 1 4/5 =

3.) Here is your 3rd growing post question.

Today in class we reviewed the 6 strategies from the RACE Investigation. They were

• Equivalence

• Fractions show operations

• Ratio Tables (Proportional Reasoning)

• Measurement

• Partial Products or the Distributive Property

• The Whole Matters

• Friendly Fractions
Create a voice thread or write and use pictures to describe how you would uses those strategies to explain how far the two students would have run if Mark ran 7/8 and Rachel ran 11/12 of the RACE course.
4. Your last question deals with pizza. You need to explain which group gets the largest portion of pizza. All student groups get the same sized pizzas. It is up to you to cut them up so that they are shared equally.

1. Group 1 Sally Bob, Gidget and Biff Share 3 pizzas.
2. Group 2 Stan, Holly, Barry, Ben and Ichkabibble share 4 pizzas.
3. Group 3 Eric, Susy,James, Betty, Veronica and Moose share 5 pizzas.
4. Group 4 Paul, Alex, Chris, Jughead, Archie, Reggie, Mr. Wotherspoon and Midge share 7 pizzas.
• How much pizza does each student get in the different groups?
• Which group gets the largest portion of pizza?
Each Person Gets 3/4 of a pizza

Each person get 4/5 of a pizza

Each Person Gets 5/6 of a pizza

Each Person gets 7/8 of a pizza

My strategies were using the slice method and using a ratio table

Group 1 gets the largest piece because the denominator is smaller so that means the larger the pieces.

Growing Post Question 1 Betty's Snack Mix Total (15 marks)

Answers all questions 5 marks (1 per Question) 5

Quality of Answers 10 marks 7

10= Perfect
8= Great Job but there is room for improvement
7= Good Job but there is much room for improvement
6= Decent job but you need to work harder
5= All work is done but effort is lacking
Less than 5 would be for questions answered incorrectly and without effort and incomplete.
