Lesson 15

Length Measurements

Lesson Purpose

The purpose of this lesson is for students to apply their understanding of multiplicative comparison and unit conversion to solve multi-step problems about distances and lengths.

Lesson Narrative

Previously, students reasoned multiplicatively about measurements and performed unit conversions to solve problems in the context of mass and capacity. In this lesson, they do the same in the context of length measurements, using familiar customary units from earlier grades (yards, feet, and inches).
