In this lesson, students solve multi-step measurement word problems. (For example, "Paula's time swimming in the Ironman Triathlon was 1 hour 25 minutes. Her time biking was 5 hours longer than her swimming time. She ran for 4 hours 50 minutes. How long did it take her to complete all three parts of the race?") 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.
