3. Lesson 5 CA Standard 1.0 Students identify and use the arithmetic properties of subsets of integers and rational, irrational, and real numbers,including closure properties for the four basic arithmetic operations where applicable. Standard 25.1 Students use properties to construct simple, valid arguments (direct and indirect) for,or formulate counterexamples toclaimed assertions. 4. Lesson 5 KC1 5. Lesson 5 Ex1 Distribute Over Addition or Subtraction EXERCISE Julia walks 5 days a week. She walks at a fast rate for 7 minutes and then cools down for 2 minutes. Rewrite 5(7 + 2) using the Distributive Property. Evaluate to find the total number of minutes Julia walks. 5 (7 + 2) = 5 7 +5 2 Distributive Property = 35 + 10 Multiply. = 45 Add. Answer: Julia walks for 45 minutes each week. 6.

Lesson 5 CYP1 A. 15 + 5 10; 65 minutes B. 5 15 + 10; 85 minutes C. 5 15 + 5 10; 125 minutes D. 15 + 10; 25 minutes WALKING Susanne walks to school and home from school 5 days each week. She walks to school in 15 minutes and then walks home in 10 minutes. Rewrite 5(15 + 10) using the Distributive Property. Then evaluate to find the total number of minutes Susanne spends walking to and home from school. 7. Lesson 5 Ex2 The Distributive Property and Mental Math Use the Distributive Property to find 12 82. 12 82 = 12( 80 + 2 ) Think: 82 = 80 + 2 = 12(80) + 12(2) Distributive Property = 960 + 24 Multiply. = 984Add. Answer: 984 8. Lesson 5 CYP2

Then simplify. 12 ( y+ 3) =12 y+12 3 Distributive Property Answer: 12 y+ 36 10. Lesson 5 Ex3 Algebraic Expressions B.Rewrite 4( y 2 + 8 y+ 2) using the Distributive Property. Then simplify. 4 ( y 2+ 8 y+ 2) =4 ( y 2 )+4 (8 y ) +4 (2) DistributiveProperty = 4 y 2+ 32 y+ 8 Multiply. Answer: 4 y 2+ 32 y+ 8 BrainPop:The Distributive Property 11.
