1. Addition & Subtraction Add by counting on Number bonds to 20 Block 1 Week 1

2. Lesson 4 Step: Number bonds to 20 (2)

3. Create bonds to 10 using the two frames. _____ and _____ make _____ 3 7 10 _____ is made of _____ and _____ 10 3 7 _____ + _____ = _____ _____ + _____ = _____ 3 7 10 7 3 10 _____ - _____ = _____ _____ - _____ = _____ 10 3 7 10 7 3

4. Create bonds to 10 using the two frames. _____ and _____ make _____ 6 4 10 _____ is made of _____ and _____ 10 6 4 _____ + _____ = _____ _____ + _____ = _____ 6 4 10 4 6 10 _____ - _____ = _____ _____ - _____ = _____ 10 6 4 10 4 6

5. Create bonds to 20 using the two sets of frames. _____ and _____ make _____ 13 7 20 _____ is made of _____ and _____ 20 13 7 _____ + _____ = _____ _____ + _____ = _____ 13 7 20 7 13 20 _____ - _____ = _____ _____ - _____ = _____ 20 13 7 20 7 13

6. Create bonds to 20 using the two sets of frames. _____ and _____ make _____ 5 15 20 _____ is made of _____ and _____ 20 5 15 _____ + _____ = _____ _____ + _____ = _____ 5 15 20 15 5 20 _____ - _____ = _____ _____ - _____ = _____ 20 5 15 20 15 5

7. Create bonds to 20 using the two sets of frames. _____ and _____ make _____ 2 18 20 _____ is made of _____ and _____ 20 2 18 _____ + _____ = _____ _____ + _____ = _____ 2 18 20 18 2 20 _____ - _____ = _____ _____ - _____ = _____ 20 2 18 20 18 2

8. Create bonds to 20 using the two sets of frames. _____ and _____ make _____ 14 6 20 _____ is made of _____ and _____ 20 14 6 _____ + _____ = _____ _____ + _____ = _____ 14 6 20 6 14 20 _____ - _____ = _____ _____ - _____ = _____ 20 14 6 20 6 14

9. Reasoning The number frames represent the number sentences represent a bond to 20. + True or false? Explain how you know. False, the number frames show 4 and 18. This makes 22 (not 20). How could this be corrected? Change the 8-piece to a 6-piece or the 4-piece to a 2-piece.

10. How many number bonds to 20 can you make using the number frames below? You may combine and use the number frames more than once. 10 + 10 = 20 17 + 3 = 20 3 + 17 = 20 13 + 7 = 20 7 + 13 = 20
