1. Quick Start Expectations 1.Pick up and Fill in planner and HWRS HW: WS Add. Practice P. 80 (Distributive Property) 2.Get a signature on your HWRS 3.L.F. turn in all HWRS for week 9 4.On desk: math journal, HWRS, pencil, pen 5.Warm Up: Simplify these expressions. (Show one operation per line below the original expression.) A. 60 – 6(3-5) 2 = B. - 40/8 + (-9) 2 =

2. Warm Up Key 60 – 6(3-5) 2 = 60 – 6(-2) 2 = 60 – 6 (-2 x -2) = 60 – 6(4) = 60 – 24 = 60 – 24 = 36 - 40/8 + (-9) 2 = - 40/8 + (-9 x -9) = - 40/8 + 81 = - 5 + 81 = 76

3. Distributive Property – 2 Forms Factored Form: Expanded Form: -3(4 + 8) = (-3 x 4) + (-3 x 8) -2(n - 6) = (-2 x n) - (-2 x 6) How can we go from factored form to expanded form? How can we go from expanded form to factored form? Lesson 4.2

4. Use the Distributive Property to expand each expression 1.) -5(3 + 2) = 2.) -5(3 – 2) = 3.) -5(3 + -2) = 4.) -5[3 –(-2)] = (-5 x 3) + (-5 x 2) (-5 x 3) – (-5 x 2) (-5 x 3) + (-5 x -2) (-5 x 3) – (-5 x -2) 4.2 B

5. Write each expression in factored form. 1.) (6 x 2) + (6 x 3) = 2.) 6 x 2 – 6 x 3 = 3.) -6 x 2 + -6 x 3 = 4. -6 x 2 – (-6) x 3 = 5.) 5x – 8x = 6.) -3x – 4x = 6(2 + 3) 6(2 – 3) -6(2 + 3) -6(2 – 3) x(5 – 8) x(-3 – 4) 4.2 C

8. Example Practice writing two different expressions to show the area of the rectangles. (Use the distributive property to help you write the expressions in expanded and factored form.) 6 x 12 + 6 x 8 = 6(12 + 8) = 6 x 20 x(14) + 2(14)= (x + 2)14 = 14x + 28 OR x 14 + 2 14 = (x + 2)14 = 14x + 28
