  2. The Distributive Property We are learning how to simplify expressions using the Distributive Property. Monday, December 1, 2014

  3. Team Investigation… • With your team simplify the given expressions using the Order or Operations. • When you are done draw lines between any expressions that have the same solution. • Last reflect with you team about What similarities do you notice between the expressions that you matched from “Column 1” and “Column 2?” • Do you see any patterns or trends?

  4. The Distributive Property A(B + C) = _________________ -or- A(B – C) = _________________ A(B) + A(C) A(B) – A(C)

  5. Use the Distributive Property to write the expression below in an equivalent form… 7(3) + 7(10) = ______________________ 6(7) – 6(3) = ______________________ 8(2) + 8(12) + 8(8) = ______________________ 3(1) - 3(4) + 3(2) – 3(7) + 3(10) = __________________________

  6. You can even use the distributive property backwards to help find the answer to a difficult multiplication problem. For example…try to multiply 9(107) by doing… 9(107) = 9(100 + 7) = 9(100) + 9(7) = 900 + 63 = 963

  7. You can even use the distributive property backwards to help find the answer to a difficult multiplication problem. For example…try to multiply 3(46) by doing… 3(46) = 3(50 – 4) = 3(50) – 3(4) Use the Distributive Property to solve the multiplication expression to multiply 8(217) = 150 – 12 = 138

  8. Which of the following would NOT be a correct way to use the Distribute Property to solve the multiplication problem (9)(146)? • (9)(100 + 40 + 5 + 1) • (9)(150 – 4) • (9)(100 + 40 + 6) • (9)(100 + 40 – 4)

  9. Which of the following expressions is equivalent to 5(6 – 8 + 10)? • 5(6) – 8 + 10 • 5(6) + 5(8) + 5(10) • 5(6) – 5(8) + 5(10) • 5 + 6 – 8 + 10

  10. In which of the following expressions is the Distributive Property used correctly? • 6(-7 + 8) = 6(-7) + 8 • 3(-9 – 1 + 3) = 3(-9) + 3(1) + 3(3) • -14(-8 + 7) = -14 + (-8) + 7 • (-3 – 5 + 2)(-15) = -3(-15) – 5(-15) + 2(-15)
