1. MATH-a-licious Monday! 1. Change group roles. 2. Warm Up: Workbook p. 34 (#5 a-e) Show your work! Find BOTH “x” and “y” Use either scale factor or ratios. 3. Write a question that deals with ratios on the note card that you think will be a challenge for others to solve. Be sure you solve it on a separate piece of paper as the answer key. ONLINE TIMER for 10 minutes

2. Warm Up Answers: WB 34 (#7-11) 7) X = 4 2/3 y = 8 8) X = 18y = 24 9) X = 21y = 24 10) X = 20y = 9 11) X = 21.6y = 20 # correct 10

3. Runners go get… New Notebook Assignment Sheets Today’s Lab Sheet ------------------------------------------------------ Make sure your Notebook Assignment Sheet looks like this: #DateBook/ Brief Description 1. 11-14C&S Problem 2.1, ACE 1-3, 9-13 BIG IDEA: Comparing ratios, percents, and fractions

4. Launch… How many of you have ever made orange juice from a can before? What was involved in making it?

8. Mix A2/5  40% Mix B5/14  35.7% Mix C1/3  33.3% Mix D 3/8  37.5% Remember part- to whole!

9. Mix A2/5  40% Mix B5/14  35.7% Mix C1/3  33.3% Mix D 3/8  37.5%

10. Nope!Yes! Because you need a part-to- whole comparison!

11. Mix A - 5 cups = 1 batch, 1 batch = 10 people, 240/10 = 24 batches Mix B - 14 cups = 1 batch, 1 batch = 28 people 240/28 = 8.57, so 9 batches Mix C - 3 cups = 1 batch, 1 batch = 6 people 240/6 = 40 batches Mix D - 8 cups = 1 batch, 1 batch = 16 people 240/16 = 15 batches

12. Mix A - 24 batches 24 x 2 = 48c. concentrate 24 x 3 = 72c. H 2 O Mix B - 9 batches 9 x 5 = 45c. concentrate 9 x 9 = 81c. of H 2 O Mix C - 40 batches 40 x 1 = 40c. concentrate 40 x 2 = 80c. H 2 O Mix D - 15 batches 15 x 3 = 45c. concentrate 15 x 5 = 75c. H 2 O Make a table to help organize! Look at next slide 

14. Discuss this question with your group and be ready to respond in 1 minute or less… On the previous slide you saw that 43 and 77 were approximations for Mix B... Why can’t you make EXACTLY 120 cups with whole numbers by scaling up the recipe?
