Lesson 13
Make 10
Lesson Purpose
Lesson Narrative
In previous lessons, students used 10frames 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 10frame 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 10frames 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).
