**Applying the IDENTITY, COMMUTATIVE, and ASSOCIATIVE properties of multiplication.**

2
Georgia Performance Standard: I can apply the identity, commutative, and associative properties of multiplication and verify the results.

3
**IDENTITY Property of Multiplication**

When you multiply a number by 1, the product is that number. EXAMPLES: 1 X 6 = 6 1 X 8 = 8 1 X 69 = 69 1 X 547 = 547

4
**COMMUTATIVE Property of Multiplication**

You can multiply two numbers in any order. The product stays the same. EXAMPLE: 6 X 7 = 42 7 X 6 = 42 7 X 6 = 6 X 7

5
**Commutative Property of Multiplication**

3 X 87 = 261 87 X 3 = 261 If 3 X 87 = 261, then 87 X 3 = 261 3 X 87 = 87 X 3

6
**ASSOCIATIVE Property of Multiplication**

When you multiply three or more numbers, it doesn’t matter which tow numbers you group or multiply first. The product will stay the same. EXAMPLE: 2 X 4 X = X 4 X 3 (2 X 4) X X (4 X 3) 8 X X 12

7
**ASSOCIATIVE Property (6 X 7) X 3 = 6 X (7 X 3) 42 X 3 = 6 X 21**

**Solve using the identity, commutative, or associative property of multiplication.**

7 X 1 = ? What property of multiplication did you use to help you solve the problem?

9
**Solve using the identity, commutative, or associative property of multiplication.**

87 X 1 = ? What property of multiplication did you use to help you solve the problem?

10
**Solve using the identity, commutative, or associative property of multiplication.**

1 X 258 = ? What property of multiplication did you use to help you solve the problem?

11
**Solve using the identity, commutative, or associative property of multiplication.**

(3 X 4) X 6 = 3 X (4 X ) What property of multiplication did you use to help you solve the problem?

12
**Solve using the identity, commutative, or associative property of multiplication.**

If 5 X 4 = 20, then 4 X 5 = What property of multiplication did you use to help you solve the problem?

13
**Solve using the identity, commutative, or associative property of multiplication.**

(63 X 2) X 12 = 63 X ( X 12) What property of multiplication did you use to help you solve the problem?
