In this lesson, students solve multi-step measurement word problems. (For example, "Lauren ran a marathon and finished 1 hour 15 minutes after Amy, who had a time of 2 hours 20 minutes. Cassie finished 35 minutes after Lauren. How long did it take Cassie to run the marathon?") For each problem, they represent the situation with a tape diagram, calculate a solution using strategies from the previous four lessons, and compare solutions with their classmates.
