Presentation Transcript

1. LI: I understand that addition and subtraction are the inverse of each other. LI: I can write inverse number sentences

2. Addition and subtraction are the opposite of each other. 3 + 7 = 10 10 7 = 3 We say that they are inverse operations.

3. What would be the inverse of: 6 + 4 = 10 10 4 = 6 It is the same numbers in a different order

4. 9 + 1 = 10 10 1 = 9

5. 5 + 5 = 10 10 5 = 5

6. 8 + 2 = 10 10 2 = 8

7. 10 1 = 9 9 + 1 = 10

8. 10 6 = 4 4 + 6 = 10

9. Remember: *An addition will become a subtraction *A subtraction will become an addition *You will have the same three numbers rearranged in a different order

10. You are going to write addition number sentences and then write the inverse underneath. For example: 6 + 4 = 10 10 4 = 6

11. Write the inverse of each of these on your board: Plenary 11 + 9 = 20 13 + 7 = 20 20 5 = 15 20 8 = 12
