1. Fact Families By Monica Yuskaitis

2. Definitions w Addend - Any number being added. 6 + 5 = 11 w Inverse Operation - An opposite operation that undoes another. 5 + 4 = 9 9 - 5 = 4

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

9. Definitions w Multiplicand - The numbers being multiplied. 4 x 8 = 32 w Inverse Operation - An opposite operation that undoes another. 4 x 8 = 32 / 4 = 8

10. Multiplication/Division Fact Families are found by: w Starting with a simple multiplication fact. ( 3 x 9 = 27) w Changing the multiplicands around. (9 x 3 = 27) w Writing the Inverse operations for both. (27 / 3 = 9 & 27 / 9 = 3)3)

11. What are the 4 members of the Fact Family of 3 x 7 = 21? w3w3 x 7 = 21 w7w7 x 3 = 21 w2w21 / 3 = 7 w2w21 / 7 = 3

12. What are the 4 members of the Fact Family of 6 x 4 = 24? w6w6 x 4 = 24 w4w4 x 6 = 24 w2w24 / 6 = 4 w2w24 / 4 = 6

13. What are the 4 members of the Fact Family of 7 x 8 = 56? w7w7 x 8 = 56 w8w8 x 7 = 56 w5w56 / 7 = 8 w5w56 / 8 = 7

14. What are the 4 members of the Fact Family of 9 x 7 = 63? w9w9 x 7 = 63 w7w7 x 9 = 63 w6w63 / 9 = 7 w6w63 / 7 = 9

15. What are the 4 members of the Fact Family of 6 x 7 = 42? w6w6 x 7 = 42 w7w7 x 6 = 42 w4w42 /6 = 7 w4w42 / 7 = 6
