# Lesson 4

Compare and Order Decimals

### Lesson Purpose

The purpose of this lesson is for students to compare and order decimals.

### Lesson Narrative

Previously, students reasoned about the relative size of decimals using number lines and other strategies. In this lesson, they apply those strategies to compare and order decimals, both in and out of context. The contexts in this lesson and in the next one share a track-and-field theme and involve measurements (running times in this lesson and jumping distances in the next lesson).
