# Lesson 4

Groups that Look Alike

### Lesson Purpose

The purpose of this lesson is for students to compare groups of objects that are close in quantity.

### Lesson Narrative

In a previous lesson, students identified groups that had more or fewer objects than a given group. The number of objects in the groups made it easy to compare the groups visually. For example, students could tell by looking that a group of two cubes was fewer than a group of nine cubes. In this lesson, students compare groups of objects that are closer in quantity. Students also practice using the words “fewer”, “more”, and “the same” in sentences that compare quantities (MP6). For example, students hear and repeat statements such as, “There are fewer red counters than yellow counters.”
