  1. MATH-a-liciousMonday! Change group roles.  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 = 18 y = 24 9) X = 21 y = 24 10) X = 20 y = 9 11) X = 21.6 y = 20 # correct 10

  3. Runners go get… • New Notebook Assignment Sheets • Today’s Lab Sheet ------------------------------------------------------ • Make sure your Notebook Assignment Sheet looks like this: • # Date Book/ Brief Description • 1. 11-14 C&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?

  5. Mix A 2/5  40% Mix B 5/14  35.7% Mix C 1/3  33.3% Mix D 3/8  37.5% Remember part-to whole!

  6. Mix A 2/5  40% Mix B 5/14  35.7% Mix C 1/3  33.3% Mix D 3/8  37.5%

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

  8. 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

  9. Mix A - 24 batches 24 x 2 = 48c. concentrate 24 x 3 = 72c. H2O Mix B - 9 batches 9 x 5 = 45c. concentrate 9 x 9 = 81c. of H2O Mix C - 40 batches 40 x 1 = 40c. concentrate 40 x 2 = 80c. H2O Mix D - 15 batches 15 x 3 = 45c. concentrate 15 x 5 = 75c. H2O Make a table to help organize! Look at next slide 

  10. 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?

  11. Make sure your Notebook Assignment Sheet looks like this: • # Date Book/ Brief Description • 1. 11-14 C&S Problem 2.1, ACE 1-3, 9-13 • Begin your ACE questions… 
