1. Division: “Facts and Properties”

2. FACTS
The quotient in a division fact is the same as a missing factor in the related multiplication fact.
If you remember the multiplication facts and how to make fact families, you will know the division facts.
Since we know 9 X 4 = 36, also know 36 / 4 = 9

3. FACTS
We can write two multiplication and two division expressions for the numbers 4, 9 and 36.
Like this, 9 X 4 = / 4 = 9
4 X 9 = / 9 = 4
These four expressions form a Fact family. The fact family for 4, 9 and 36 can also be written in vertical form.
÷ ÷9
X X

4. PROPERTIES
Division has several properties that can help you remember some division facts.
If the divisor is 1, the quotient is the same as the dividend. 5
1/ ÷ 1 = 9

5. PROPERTIES
If the divisor and the dividend are the same number, the quotient is 1. 1
8 / ÷ 6 = 1

6. PROPERTIES If the dividend is zero, the quotient is zero. 0 0 ÷ 7 = 0
÷ 7 = 0
2/ 0

7. PROPERTIES
NEVER divide by zero.
