Basic Properties to solve problems Test Tomorrow!!!

Commutative Associative Distributive Identity Zero properties Today we are reviewing for our unit test tomorrow on the properties of operations

White Boards! I will state a property and you will write an example of an expression that demonstrates that property on your white boards.

Which property is illustrated by the following problem? (DOK 1) 56 x (2 + 3) = (56 x 2) + (56 x 3) a) Associative property of multiplication b) Commutative property of multiplication c) Distributive property of multiplication over addition d) Distributive property of multiplication over subtraction

Which property is illustrated by the following problem? (DOK 1) (56 x 3) – (56 x 2) = 56 x (3 – 2) a) Associative property of multiplication b) Commutative property of multiplication c) Distributive property of multiplication over addition d) Distributive property of multiplication over subtraction

Lacy used mental math to know that if 3a = 3, then a = 1. Which property did she use? (DOK 3) a) Associative property of multiplication b) Commutative property of multiplication c) Identity property of multiplication d) Zero property of multiplication

If a x b = 0 then what do we know about a or b? (DOK 3) a) Both variables must be greater than 0. b) Both variables must be equal to 0. c) At least on variable must be 0. d) There is not enough information.

Solve. 5 x 4/5 x 0 = _______ (DOK 2) a) -25 b) -5 c) 0 d) 1

Which of the following demonstrates the distributive property of multiplication over subtraction? (DOK 1) a) a – b = a – b b) a x (b – c) = (a – b) x (a – c) c) a x (b – c) = (a x b) - (a x c) d) a x 1 = a

Which of the following demonstrates the commutative property of multiplication? (DOK 1) a) a x b = b x a b) (a x b) x c = a x (b x c) c) a x (b – c) = (a x c) - (b x c) d) a x b = a x b

Which of the following choices will result in an answer of 1? (DOK 2) a) 1 added to 0. b) 0 subtracted from 1. c) Multiply a number by 1. d) All of the above

Which of the following choices will result in an answer of 0? (DOK 3) a) Add a number and its opposite. b) Multiply a number by 0. c) Multiply the number 0 by 1. d) All of the above

The commutative property works for which operations? (DOK 2) a) Addition b) Subtraction c) Division d) All of the above

Which of the following choices are not true? (DOK 3) a) a + b = b + a b) a – b = b – a c) a x b = b x a d) None of the above

The problem 0 x 1 = 1 x 0 illustrates which property? (DOK 3) a) Commutative property of multiplication b) Identity property of multiplication c) Zero property of multiplication d) All of the above

Let n equal 5. Solve (n + 0) x 1. (DOK 2) a) 0 b) 1 c) 5 d) 10

What have you learned? Monday- Zero Property and Identity property. Tuesday- Commutative property. Wednesday- Associative property. Thursday- Distributive property. Friday- All of them together.
