Topic E: Represent and Apply Compositions and Decompositions of Teen Numbers

Lesson 20 Concept Development and Problem Set

Each student got 6 colored pencils and 4 regular pencils. How many pencils did each student get? Draw a picture, a number bond, and write a number sentence, too.

Fill in the number bonds and write a number sentence to match it.

13 = ____ + ____

15 = _____ + _____

17 = _____ + _____

10 + 8 = _____

10 + 6 = _____

_____ = 10 + 4

1. In a number bond, which number is larger, the whole or a part?

2. Explain how the teen numbers are 10 ones and some more ones.

3. Look at each number bond as I say the whole. You read the number the Say Ten way, e.g., I say 13 and you say ten three.

4. Mental math: I say 16, you say 10 + 6.

5. Show a row of ten on the Rekenrek, and then slide beads to show the teen numbers. Students say the numbers the regular and the Say Ten way.

6. What are we doing with the parts when we add? Are we putting them together or taking them apart?

Lesson 20 Homework

Draw stars to show the number as a number bond of 10. Show each example as two addition sentences of 10 ones and some ones.
