  1. Fact Families By Mr. Cole

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

  3. Addition/Subtraction Fact Families are found by: • Starting with a simple addition fact. ( 2 + 5 = 7) • Changing the addends around. • (5 + 2 = 7) • 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? • 3 + 4 = 7 • 4 + 3 = 7 • 7 - 3 = 4 • 7 - 4 = 3

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

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

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

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

  9. Definitions • Factors- The numbers being multiplied. • 4 x 8 = 32 • Inverse Operation - An opposite operation that undoes another. • 4 x 8 = 32 32 ÷ 4 = 8

  10. Multiplication/Division Fact Families are found by: • Starting with a simple multiplication fact. ( 3 x 9 = 27) • Changing the factors around. • (9 x 3 = 27) • 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? • 3 x 7 = 21 • 7 x 3 = 21 • 21 ÷ 3 = 7 • 21 ÷ 7 = 3

  12. What are the 4 members of the Fact Family of 6 x 4 = 24? • 6 x 4 = 24 • 4 x 6 = 24 • 24 ÷ 6 = 4 • 24 ÷ 4 = 6

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

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

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

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

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

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

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

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