1 The Distributive Property

2 The distributive property is mental math strategy that can be used when multiplying. 43 x 5 =?

3 Break apart the double-digit number. 43 x 5 =?

4 Then multiply each part by x 5 =? 40 3 x 5 x 5 +

5 Then multiply each part by x 5 =? 40 3 x 5 x

6 Finally, sum your two products 43 x 5 = x 5 x = 215 +

7 Let’s look at another example. 53 x 6 = ?

8 Break apart the double-digit number. 53 x 6 = ?

9 Break apart the double-digit number. 53 x 6 = ?

10 Multiply each part by x 6 = ? 50 3 x 6 x 6 +

11 Multiply each part by x 6 = ? 50 3 x 6 x

12 Sum the two products. 53 x 6 = x 6 x = 318 +

13 There are three steps to the distributive property. 4 x 28 =

14 There are three steps to the distributive property. 4 x 28 = 1) Break apart the double-digit number.

15 There are three steps to the distributive property. 4 x 28 = 4 x (20 + 8) 1) Break apart the double-digit number.

16 There are three steps to the distributive property. 4 x 28 = 4 x (20 + 8) 1)Break apart the double-digit number. 2)Multiply each part by 4. (distribute the 4)

17 There are three steps to the distributive property. 4 x 28 = 4 x (20 + 8) = (4 x 20) + (4 x 8) 1)Break apart the double-digit number. 2)Multiply each part by 4. (distribute the 4)

18 There are three steps to the distributive property. 4 x 28 = 4 x (20 + 8) = (4 x 20) + (4 x 8) 1)Break apart the double-digit number. 2)Multiply each part by 4. (distribute the 4) 3)Sum the two products.

19 There are three steps to the distributive property. 4 x 28 = 4 x (20 + 8) = 80 + (4 x 8) 1)Break apart the double-digit number. 2)Multiply each part by 4. (distribute the 4) 3)Sum the two products.

20 There are three steps to the distributive property. 4 x 28 = 4 x (20 + 8) = )Break apart the double-digit number. 2)Multiply each part by 4. (distribute the 4) 3)Sum the two products.

21 There are three steps to the distributive property. 4 x 28 = 4 x (20 + 8) = = 112 1)Break apart the double-digit number. 2)Multiply each part by 4. (distribute the 4) 3)Sum the two products.

22 The word “distribute” means “to give out.”

29 In this example, the 5 was distributed. 5 x 38 = 5 x (30 + 8) = (5 x 30) + (5 x 8)

30 In this example, the 7 was distributed. 7 x 46 = 7 x (40 + 6) = (7 x 40) + (7 x 6)
