LINKING MULTIPLICATION AND DIVISION

Multiplication are OPPOSITES of each other. In math we call then INVERSES.

 

If 6 X 4 = 24; then writing it backwards we get 24 ÷ 4 = 6.

For each FACT, we can write the FACT FAMILY. It uses the commutative property of multiplication that we used earlier. If 6 X 4 = 24 then 4 X 6 = 24. In division, we can swithc out the divisors: We can write:

24 ÷ 4 = 6 but can also switch the 4 and the 6 to write: 24 ÷ 6 = 4. So our FACT FAMILY WOULD LOOK LIKE THIS:

 

6 X 4 = 24

24 ÷ 4 = 6

4 X 6 = 24

24 ÷ 4 = 6

 

Let's work on another FACT FAMILY:

 

3 X 4 = 12

12 ÷ 3 = 4

4 X 3 = 12

12 ÷ 4 = 3

 

Now I will give you 1 piece of the family and you practice writing the other 3 pieces:

Fact Family Practice

 

1. 5X4 = 20

2. 6X3 = 18

3. 9X5 = 45

4. 7X8 = 56

5. 42÷7 = 6

6. 15÷3 = 5

7. 72÷8 = 9

8. 48÷6 = 8
