The purpose of this lesson is for students to use objects to show the action of addition.
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.
- Use objects to show the action of addition.
- Let’s use counters to add.
- Cut out enough 5-frames to make a chart with a space for each student to answer the survey question.
- Each group of 2 needs 1 connecting cube.
- Gather materials from:
- 5-Frames, Stage 1
- Roll and Add, Stage 1
- Math Libs, Stage 1
- Match Mine, Stage 1

Teacher Reflection Questions
Think about who volunteered to share their thinking with the class today. Are the same students always volunteering, while some students never offer to share? What can you do to help the class understand the value of hearing the ideas of every mathematician?
