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.
