Today’s Agenda Homework is out on the corner of your desk, 11/4/15 ACTIVATOR: Homework is out on the corner of your desk, copy down tonight’s homework. 3. Activator: Take out your math packet and notebook. In your notebook put today’s date in the corner, and Activator on the first line. Copy and Answer: For every 3 girls, there are 4 boys. There are 21 children in the class. How many boys are there? HINT: Make a table!!

November 4, 2015 [Day F] I will be able to create multiple ratios from a context in which more than two quantities are given to complete pg. 5 of my packet. I will also be able to use tape diagrams to solve problems when the part-to part ratio is given and the value of one of quantities is given to complete pg. 8 of my packet. 6.RP.A.1 6.RP.A.3

Exercise 1 pg. 4 (2 mins.) Come up with two examples of ratio relationships that are interesting to you.

Read and study the description of the data in the chart on pg. 4. Answer the exploratory challenge problems on pgs. 4 and 5 Are the ratios 2:5 and 5:2 the same? Why or why not? Without looking back at the description, what is the chart about? Based on the survey, should the company order more pink fabric or more orange fabric? What is the ratio of the number of bolts of pink fabric to number of bolts of orange fabric you think the company should order? Someone said 5 to 3 and my friend said 3 to 5. Are those the same? Is a ratio of 3 to 5 the same as a ratio of 5 to 3? Remember, the ordering of the words in the description of the ratio relationship is what determines the order of the numbers in the ratio.

Ratios that have the same value Write a one-sentence story problem about a ratio. Equivalent ratio Ratios that have the same value Ex. 4:7 is equivalent to 12:21 Without looking back at the description, what is the chart about? Based on the survey, should the company order more pink fabric or more orange fabric? What is the ratio of the number of bolts of pink fabric to number of bolts of orange fabric you think the company should order? Someone said 5 to 3 and my friend said 3 to 5. Are those the same? Is a ratio of 3 to 5 the same as a ratio of 5 to 3? Remember, the ordering of the words in the description of the ratio relationship is what determines the order of the numbers in the ratio.

Exercise 2 (7 min.): Lets represent this ratio in a table. The length of Shanni’s Ribbon (in inches) The length of Mel’s Ribbon (in inches) 7 3 14 6 21 9 We use a tape diagram to represent the ratio of the lengths of ribbon. Let’s create one. 

Tape Diagram (Bar Model)

Equivalent Ratio!

Exercise 3: (a) Mason and Laney ran laps to train for the long-distance running team. The ratio of the number of laps Mason ran to the number of laps Laney ran was 2 to 3. If Mason ran 4 miles, how far did Laney run?

Exercise 3 : (b) If Laney ran 930 meters, how far did Mason run? Draw a tape diagram to determine how you found the answer.

4:6 and 620:930 (c) What ratios can we say are equivalent to 2:3? Exercise 3 : (c) What ratios can we say are equivalent to 2:3? 4:6 and 620:930

Exercise 4 : Josie took a long multiple-choice, end-of-year vocabulary test. The ratio of the number of problems Josie got incorrect to the number of problems she got correct is 2:9. (a) If Josie missed 8 questions, how many did she get correct? Draw a tape diagram to demonstrate how you found the answer.

Exercise 4 : (b) If Josie missed 20 questions, how many did she get correct? Draw a tape diagram to demonstrate how you found the answer. (c) What ratios can we say are equivalent to 2:9? 8:36 and 20:90

(d) Come up with another possible ratio of the number Josie got incorrect to the number she got correct. (e) How did you find the numbers? (f) Describe how to create equivalent ratios. Multiply both numbers of the ratio by the same number.

EXIT TICKET: write the Answers in your TTG page Pam and her brother both open savings account. Each began with $0. For every $2 that Pam saves in her account, her brother saves $5 in his account. If Pam has $40 in her account, how much money does her brother have in his account? Use a tape diagram to support your answer. HOMEWORK: Lesson 3: Ratios Problem Set #1-4 (page S.11)
