Reflection: Problem-based Approaches Finals Week Day 1 - Section 6: Focusing on One Idea


Students used calculators to create unit rates in order to compare the caffeine concentration of each drink.  Some students rounded to nearest mg of caffeine in one ounce, which created a tie for third place between Monster and Red Bull.  Other students rounded to nearest ounce before they calculated the unit rates.  Common mistakes included division mistakes and rounding errors.

Finals Week Day 1

Unit 5: Proportional Reasoning: Ratios and Rates
Lesson 18 of 21

Objective: SWBAT: • Define rate and give examples of how they can use rates. • Describe the problem posed in “Finals Week” and identify the needed information. • Brainstorm ideas of how to solve the problem. • Use a strategy to solve the problem and show their math thinking. • Use peer feedback to revise their solution and work.

Big Idea: Which drink has the strongest caffeine concentration? How will you figure out this problem? What information do you need to figure this out? Students work on this problem for the first of two lessons.
