Reviewing Multiplication and the Properties

Vocabulary

100

The answer to a multiplication equation is called ...

the product

200

The numbers being multiplied together are called...

the factors

300

This property of multiplication tells me I can flip flop the factors in a multiplication equation and the product with stay the same

the commutative property of multiplication

400

This property of multiplication tells me I can break apart a larger factor into two small factors to make a multiplication problem easier to solve.

Distributive Property

500

This property of multiplication tells me that no matter how I group the factors the product will not change

The associative property of multiplication

Distributive Property

100

Solve the equation 6 X 9 

break apart one of the factors to make it easier to solve.

54

200

Solve the equation 7 X 6

Break apart one of the factors to make it easier to solve.

42

300

A student says the equations 

8 X 2 and (4 X 2) + (4 X 2) 

will both have the same product. Do you agree or disagree with this student. EXPLAIN WHY.

Agree

The distributive property of multiplication was used to break apart 8 into 4 + 4

400

A student says the equations 

9 X 6 and 6X(5+5)

will both have the same product. Do you agree or disagree with this student. EXPLAIN WHY.

Disagree

These two equations will have different products because 5 + 5 does not equal 9 so I know that the student did not break apart 9 correctly. They could fix this by making the equation 6X(5+4)

500

Use the distributive property to solve this equation:

20 X 6

120

Associative Property

100

Fill in the unknown factor:

(5 X 2)  X 3 = 5 X (2 X ?)

(5 X 2)  X 3 = 5 X (2 X 3)

200

Find the product of:

(3 X 4) X 2

The product is 24

300

If I know that (5 X 2) X 6 = 60 then what do I know about the equation 5 X (2 X 6) ?

It will also have a product of 60.

400

Solve the equation:

6 X ( 2 X 2 )

24
