Lesson 8
Filling up the World's Largest Wagon
Lesson Purpose
Lesson Narrative
The purpose of this lesson is for students to solve problems about filling the world’s largest toy wagon. In the previous lesson students estimated the volume of the Radio Flyer using information from an image. In this lesson, students are given the dimensions of the wagon and they calculate its volume as the first step in solving problems about how many bags of sand and how many boxes of a given dimension it takes to fill the wagon. Students use what they have learned about volume, the standard algorithm for multiplication, and partial quotients to solve these problems.
