# Lesson 16

Partes que forman 5

### Lesson Purpose

The purpose of this lesson is for students to develop fluency with adding and subtracting within 5.

### Lesson Narrative

Students practice finding the missing part with groups of up to 5 objects in the first activity. In the second activity, students fill in equations with a missing value that all equal the same number. The second activity is optional because determining the missing value of an equation is not required by the kindergarten standards.

If students need additional support with the concepts in this lesson, refer back to Unit 5, Section A in the curriculum materials.
