1. Fact Families By Mr. Cole

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) w Changing the addends around. (5 + 2 = 7) w Writing the Inverse operations for both. (7 - 2 = 5 & 7 - 5 = 2)

4. What are the 4 members of the Fact Family of 3 + 4 = 7? w 3 + 4 = 7 w 4 + 3 = 7 w 7 - 3 = 4 w 7 - 4 = 3

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

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

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

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

9. Definitions w Factors- The numbers being multiplied. 4 x 8 = 32 w Inverse Operation - An opposite operation that undoes another. 4 x 8 = 32 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 factors around. (9 x 3 = 27) w Writing the Inverse operations for both. (27 ÷ 3 = 9 & 27 ÷ 9 = 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? w 6 x 4 = 24 w 4 x 6 = 24 w 24 ÷ 6 = 4 w 24 ÷ 4 = 6

13. What are the 4 members of the Fact Family of 7 x 8 = 56? w 7 x 8 = 56 w 8 x 7 = 56 w 56 ÷ 7 = 8 w 56 ÷ 8 = 7

14. What are the 4 members of the Fact Family of 9 x 7 = 63? w 9 x 7 = 63 w 7 x 9 = 63 w 63 ÷ 9 = 7 w 63 ÷ 7 = 9

15. What are the 4 members of the Fact Family of 6 x 3 = 18 ? w 6 x 3 = 18 w 3 x 6 = 18 w 18 ÷ 6 = 3 w 18 ÷ 3 = 6

16. What are the 4 members of the Fact Family of 9 x 3 = 27? w 9 x 3 = 27 w 3 x 9 = 27 w 27 ÷ 9 = 3 w 27 ÷ 3 = 9

17. What are the 4 members of the Fact Family of 6 x 2 = 12 ? w 6 x 2 = 12 w 2 x 6 = 12 w 12 ÷ 6 = 2 w 12 ÷ 2 = 6

18. What are the 4 members of the Fact Family of 5 x 6 = 30 ? w 5 x 6 = 30 w 6 x 5 = 30 w 30 ÷ 5 = 6 w 30 ÷ 6 = 5

19. What are the 4 members of the Fact Family of 7 x 6 = 42 ? w 7 x 6 = 42 w 6 x 7 = 42 w 42 ÷ 7 = 6 w 42 ÷ 6 = 7

20. What are the 4 members of the Fact Family of 6 x 9 = 54 ? w 6 x 9 = 54 w 9 x 6 = 54 w 54 ÷ 6 = 9 w 54 ÷ 9 = 6
