Lesson 13

Make 10

Lesson Purpose

The purpose of this lesson is for students to find the number that makes 10 when added to a given number.

Lesson Narrative

In previous lessons, students used 10-frames and fingers to compose and decompose 10 in more than one way. In the previous lesson, students used the structure of a partially filled in 10-frame to determine how many more needed to be added to make 10. In this lesson, students develop strategies for finding the number that makes 10 when added to a given number.

While students may use any method that makes sense to them to find the given number, using 10-frames and fingers is highlighted because the structure allows students to see how many more are needed to make 10. As they choose a strategy, they will be making use of appropriate tools strategically (MP5).
