# Lesson 4

### Lesson Purpose

The purpose of this lesson is for students to use objects to show the action of addition.

### Lesson Narrative

In previous lessons, students counted two groups to find the total. They heard and used addition language such as ”put together,” “altogether,” “total,” and “2 and 3 is 5.” In this lesson, students begin with 1 group of counters and add more. They count to find the total number of counters. Students continue to hear and use addition language in this lesson.
