Unit 8, Lesson 12
Make Dot Images
Kindergarten
Preparation
Lesson Purpose
The purpose of this lesson is for students to develop fluency with adding and subtracting within 5 as they identify compositions and decompositions of numbers to 5.
Lesson Narrative
Students participate in a How Many Do You See? routine and then create their own dot images to use in a version of the routine in small groups. Understanding that numbers can be composed and decomposed in multiple ways is an important step toward adding and subtracting fluently within 5. When they make dot images and share with their partners, students practice fluency for arithmetic facts within 5, through visualization (MP7).
If students need additional support with the concepts in this lesson, refer back to Unit 5, Section A in the curriculum materials.

NoneTeacher Reflection Questions
As students worked with their partners and small groups today, whose ideas were heard, valued, and accepted? How can you adjust the group structure going forward to ensure each student’s ideas are part of the collective learning?
