The distributive property is mental math strategy that can be used when multiplying.

43 x 5 =?

Let’s look at another example. be used when multiplying.

53 x 6 = ?

Break apart the double-digit number. be used when multiplying.

53 x 6 = ?

There are three steps to the distributive property. be used when multiplying.

4 x 28 =

There are three steps to the distributive property. be used when multiplying.

4 x 28 =

1) Break apart the double-digit number.

There are three steps to the distributive property. be used when multiplying.

4 x 28 = 4 x (20 + 8)

1) Break apart the double-digit number.

There are three steps to the distributive property. be used when multiplying.

4 x 28 = 4 x (20 + 8)

- Break apart the double-digit number.
- Multiply each part by 4. (distribute the 4)

There are three steps to the distributive property. be used when multiplying.

4 x 28 = 4 x (20 + 8) = (4 x 20) + (4 x 8)

- Break apart the double-digit number.
- Multiply each part by 4. (distribute the 4)

There are three steps to the distributive property. be used when multiplying.

4 x 28 = 4 x (20 + 8) = (4 x 20) + (4 x 8)

- Break apart the double-digit number.
- Multiply each part by 4. (distribute the 4)
- Sum the two products.

There are three steps to the distributive property. be used when multiplying.

4 x 28 = 4 x (20 + 8) = 80 + (4 x 8)

- Break apart the double-digit number.
- Multiply each part by 4. (distribute the 4)
- Sum the two products.

There are three steps to the distributive property. be used when multiplying.

4 x 28 = 4 x (20 + 8) = 80 + 32

- Break apart the double-digit number.
- Multiply each part by 4. (distribute the 4)
- Sum the two products.

There are three steps to the distributive property. be used when multiplying.

4 x 28 = 4 x (20 + 8) = 80 + 32 = 112

- Break apart the double-digit number.
- Multiply each part by 4. (distribute the 4)
- Sum the two products.

The word “distribute” means be used when multiplying.“to give out.”
