1. Fact Families

2. On the next 4 slides create examples of addition/subtraction fact families.

3. Addition/Subtraction Fact Families are found by: w Starting with a simple addition fact. ( 2 + 5 = 7)7) w Changing the addends around. (5 + 2 = 7)7) w Writing the Inverse operations for both. (7 - 2 = 5 & 7 - 5 = 2)2)

4. What are the 4 members of the Fact Family of 3 + 4 = 7? w3w3 + 4 = 7 w4w4 + 3 = 7 w7w7 - 3 = 4 w7w7 - 4 = 3

5. What are the 4 members of the Fact Family of 8 + 1 = 9? w8w8 + 1 = 9 w1w1 + 8 = 9 w9w9 - 8 = 1 w9w9 - 1 = 8

6. What are the 4 members of the Fact Family of 11 + 5 = 16? w1w11 + 5 = 16 w5w5 + 11 = 16 w1w16 - 11 = 5 w1w16 - 5 = 11

7. What are the 4 members of the Fact Family of 9 + 7 = 16? w9w9 + 7 = 16 w7w7 + 9 = 16 w1w16 - 9 = 7 w1w16 - 7 = 9

8. What are the 4 members of the Fact Family of 12 + 7 = 19? w1w12 + 7 = 19 w7w7 + 12 = 19 w1w19 - 12 = 7 w1w19 - 7 = 12
