Fact Family

1. Fact Families

2. Objective
Today we will learn to write multiplication
and division fact families.

3. Definitions
 Addend - Any number being
added.
6 + 5 = 11
 Inverse Operation - An opposite
operation that undoes another.
5 + 4 = 9 9 - 5 = 4
Let’s Review

4. 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)

5. 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

6. 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

7. 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
Multiplication

8. 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)

9. 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

10. 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

11. 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)

12. 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
Guided

13. 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

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

15. 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)
CFU

16. Closure
 A fact family will have two
multiplication problems and two
division problems.
Inverse Operation - An opposite
operation that undoes another.
3x4=12 *** 12 ÷ 4 = 3

17. Independent Practice
 Write a multiplication and division fact
family for the following:
 1) 5 x6 = 30 6) 9x8 = 72
 2) 8x3 = 24 7) 4x8 = 32
 3) 7x2 = 14 8) 3x9 = 27
4) 6x8 = 48 9) 9x 2 =18
5) 2x4 = 8 10) 4x 6 = 24

18. Answers
 1) 5 x6 = 30 6x5=30 30 ÷ 6=5 30 ÷ 5=6
 2) 8x3=24 3x8=24 24 ÷ 8=3 24 ÷ 3=8
 3) 7x2=24 2x7=14 14 ÷ 2=7 14 ÷ 7=2
 4) 6x8=48 8x6=48 48 ÷ 6=8 48 ÷ 8=6
 5) 2x4=8 4x2=8 8 ÷ 4=2 8 ÷ 2=4

19. 6) 9x8=72 8x9=72 72 ÷ 9=8 72 ÷ 8=0
7) 4x8=32 8x4=32 32 ÷ 8=4 32 ÷ 4=8
8) 3x9=27 9x3=27 27 ÷ 9=3 27 ÷ 3=9
9) 9x2=18 2x9=18 18 ÷ 9=2 18 ÷ 2=9
10) 4x6=24 6x4=24 24 ÷ 6=4 24 ÷ 4=6
