  1. Properties of Addition Lesson by Vi Thai

  2. Properties Unit • Middle School • This lesson on the properties of addition should come after students have done a quick review of addition. This power point presentation is to accompany the introductory lesson.

  3. Commutative Property of Addition Algebraically: a + b = _____ b + a Frogs + Flies = ___________ Flies + Frogs Shoes + Socks = _____________ Socks + Shoes Numerically: 5 + 3 = _____ 3 + 5 8 = 8 6 + 8 = _____ 8 + 6 14 = 14

  4. Associative Property of Addition Algebraically: (a + b ) + c = ____________ a + (b + c) (Chickens + Ducks) + Horses = _________________________ Chickens + (Ducks + Horses) (Keyboard + Mouse) + Monitor = _________________________ Keyboard + (Mouse + Monitor) Numerically: (3 + 5 ) + 7 = ____________ 3 + (5 + 7) 15 = 15 (2 + 7 ) + 5 = ____________ 2 + (7 + 5) 14 = 14

  5. Distributive Property Multiplication over Addition Algebraically: 5 * (a + b ) = ________ 5a + 5b 5 Apples + 5 Bananas 5 * (Apples + Bananas) = 5(3) + 5(4) = ______ 5 * (3 + 4) = _________ 15 + 20 = ___ 35

  6. Let’s do a quick review! In the next few slides, you will be asked to complete each question with the correct answer. Choose a, b, c or d. Good luck!

  7. The Commutative Property States that: • a + b = a + b a. c. b – a b + a a – b b. d.

  8. Correct! • The Commutative Property states: a + b = b + a • Go to the next question!

  9. Sorry! • Your answer is incorrect! Please try again!

  10. The Associative Property States that: • a + (b + c) = (a + b + c) a. c. (a + c) + b (a + b) - c (a + b) + c b. d.

  11. Correct! • The Associative Property states: a + (b + c) = (a + b) + c • Go to the next question!

  12. Sorry! • Your answer is incorrect! Please try again!

  13. The Distributive Property states: 2 * (x + y) = 2x + y a. c. 2x + 2y x + 2y 2x – 2y b. d.

  14. Sorry! • Your answer is incorrect! Please try again!

  15. Correct! • The Distributive Property states: 2 * (x + y) = 2x + 2y • Great job! You have completed the review! END
