  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 =? 40 3 +

  4. Then multiply each part by 5. 43 x 5 =? 40 3 + x 5x 5

  5. Then multiply each part by 5. 43 x 5 =? 40 3 + x 5x 5 200 15

  6. Finally, sum your two products 43 x 5 =215 40 3 + x 5x 5 200 15 + = 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 = ? 50 3 +

  10. Multiply each part by 6. 53 x 6 = ? 50 3 + x 6x 6

  11. Multiply each part by 6. 53 x 6 = ? 50 3 + x 6x 6 300 18

  12. Sum the two products. 53 x 6 = 318 50 3 + x 6x 6 300 + 18 = 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) • Break apart the double-digit number. • 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) • Break apart the double-digit number. • 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) • Break apart the double-digit number. • Multiply each part by 4. (distribute the 4) • Sum the two products.

  19. There are three steps to the distributive property. 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.

  20. There are three steps to the distributive property. 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.

  21. There are three steps to the distributive property. 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.

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

  23. Distribute the cubes to the girls.

  24. Distribute the cubes to the girls.

  25. Distribute the cubes to the girls.

  26. Distribute the cubes to the girls.

  27. Distribute the cubes to the girls.

  28. Distribute the cubes to the girls.

  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)
