Worksheets for Kindergarten, module 5, lesson 20

Worksheets, solutions, and videos to help Kindergarten students learn how to represent teen number compositions and decompositions as addition sentences.

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

- In a number bond, which number is larger, the whole or a part?
- Explain how the teen numbers are 10 ones and some more ones.
- 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.
- Mental math: I say 16, you say 10 + 6.
- 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.
- 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.

Learning Goal

I can break apart teen numbers in different ways.
