Name Chapter 6, Lesson 2 Reteach Date Use the Distributive Property CA Standards AF 1.3, MR 1.1 Two Ways to Use the Distributive Property to Multiply Method 1 Add the numbers. Then multiply by the first factor. Method 2 Multiply each addend by the first factor. Then add the products. a(b + c) (a × b) (a × c) = 5 × (13 + 17) = 5 × 30 = 150 = (5 × 13) + (5 × 17) = 65 + 85 = 150 Use the Distributive Property to ﬁnd the value of the variable. 1. 7 × 45 = (v × 40) + (7 × 5) 5. 8 × 64 = (8 × 34) + (8 × k) 2. 9 × c = (9 × 20) + (9 × 9) 6. 3 × 73 = (3 × h) + (3 × 40) 3. p × 38 = (4 × 25) + (4 × 13) 7. 9 × 63 = (z × 52) + (9 × 11) 4. 6 × 56 = (6 × 30) + (6 × m) 8. 4 × y = (4 × 39) + (4 × 39) Writing Math Use the Distributive Property to explain why both of these number sentences can be used to find 6 × 56. 6 × (50 + 6) = (6 × 50) + (6 × 6) 6 × (34 + 22) = (6 × 34) + (6 × 22) Reteach Use with text pages 124–125.
