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).
- Fill in equations to represent compositions and decompositions of 10.
- Find the number that makes 10 when added to a given number.
- Let’s make 10.
