Lesson 3
Metric Conversion and Multiplication by Powers of Ten
Lesson Purpose
Lesson Narrative
In this lesson, students apply place value reasoning to convert between different metric lengths. Students notice patterns in whole number and decimal products when a number is multiplied by a power of 10 (MP7). This builds on the previous lesson where students studied powers of 10. This is the first of several lessons that focus on metric units, specifically length, which all differ by powers of 10. The contexts for the first two lessons come from different events in track and field. This lesson focuses on the standing broad jump and longer distance runs.
