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
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
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.
I can break apart teen numbers in different ways.
