Walking to School (Solve multiplicative comparison word problems involving finding the size of the group using bar model

The video tutorial explains how to determine the walking distance from Sarah's house to school using bar models. It introduces the problem of comparing Sarah's and Lily's walking distances, with Lily's being three times longer. By constructing a bar model, the tutorial demonstrates how to represent and solve the equation to find Sarah's distance, which is 300 feet. The lesson concludes with a summary of using bar models for solving multiplicative comparison problems.

If Lily's house is 900 feet from the school, how can we express the relationship between the distances using a bar model?

How does the distance from Lily's house to the school compare to the distance from Sarah's house?

What mathematical operation do we perform to find the distance from Sarah's house to the school?

What is the distance from Sarah's house to the school?

Explain how you can use bar models to solve multiplicative comparison problems.
