100

5 X 3 = 3 X a What is the value of a?

5

Jahmere said because he knows 6 x 4 he also knows 4 x 6. Is he correct? Explain.

Yes, he is correct. The commutative property says you can just turn the numbers around and get the same product.

7 x 2 = 2 x a

7

What is another name for the Commutative Property?

order property/ Turn around rule

500

Explain in writing what the commutative property?

The commutative property says that you can change the order of your factors and still get the same product.

Distributive Property

100

3 x 20 = (3 x 10) + (3 x a)

10

200

Use the distributive property to solve: 4 x 8=

(2 x 8)+ (2+8) or (4 x 5) + (4 x 3)

300

How can the distributive property help you solve "hard facts"?

You can use the distributive property to break the harder facts into two smaller easier facts, then solve

400

Use the distributive property to find the product of 8 x 7=

(4 x 7) + (4 x 7) or (8 x 2) + (8 x 5)

500

Write an equation of what the distributive property is.

2 * (3 *4) = (2* 3) + (2* 4) or something like that 

Identity and Zero Property

100

What is the identity property of multiplication?

The identity property says that you can multiply by 1 and you are always going to get the other number

200

What is the zero property of multiplication?

The zero property says that the product of any number and zero is always zero.

Write an equation using the zero property and identity property

Example: 7 x 0= 0 or 4 x 1= 4

Which Property am I?
