The document teaches about writing multiplication and division fact families. It defines key terms like factors and inverse operations. It provides examples of writing the four facts that make up a fact family, such as changing the order of factors or operands and finding the inverse operations. Students are guided through writing fact families for multiplication and division problems and provided with the answers.

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
