RN Teaching Properties

- 1. Because of the commutative property we can add or multiply in any order if there is only addition or only multiplication. 3 + 4 = 4 + 3 is an example of the commutative property. Find the other example.
A) a + b = b + a B) (a + b) + c = a + (b + c) C) a(b + c) = a x b + a x c D) 5 + 0 = 5 - 2. We can group the numbers or variables in any combination as long as we only have addition or multiplication signs because of the associative property. 3 + (4 + 5) = (3 + 4) + 5 is an example of the associative property. Find another example of the associative property.
A) a + b = b + a B) (a + b) + c = a + (b + c) C) 5 + 0 + 5 D) a(b + c) = a x b + a x c - 3. The sum of 0 and any number equals that number is an example of the identify property of addition. Find another example of the identify property.
A) a(b + c) = a x b + a x c B) 5 + 0 = 5 C) (a + b) + c = a + (b + c) D) a + b = b + a - 4. In the distributive property the number with its sign that is outside the parenthesis needs to be multiplied by every number and variable inside the parenthesis. 4(2 + 3) = 4 x 2 + 4 x 3 is an example of the distributive property. Find another example of it.
A) a + b = b + a B) (a + b) + c = a + (b + c) C) 5 + 0 = 5 D) a(b + c) = a x b + a x c - 5. As long as all operations are multiplication or addition the commutative property allows us to rearrange the numbers to make the math easier. An example is 3 x 4 x 5 might to easier as 4 x 5 x 3. Find another example.
A) 5 x 1 = 5 B) (2 + 4) + 6 = 2 + (4 + 6) C) 6 x 5 x 2 = 2 x 5 x 6 D) 2(3 + 4) = 6 + 8 - 6. As long as all operations are addition or multiplication we can move the parenthesis to new numbers because of the associative property. a + (b + c) = (a + b) + c is an example. Find another example.
A) 5 x 1 = 5 B) (2 + 4) + 6 = 2 + (4 + 6) C) 2(3 + 4) = 6 + 8 D) 6 x 5 x 2 = 2 x 5 x 6 - 7. Multiplying a number by one does not change its identify. This is an example of the identity property of multiplication. 8 x 1 = 8. Find another example.
A) 5 x 1 = 5 B) 2(3 + 4) = 6 + 8 C) 6 x 5 x 2 = 2 x 5 x 6 D) (2 + 4) + 6 = 2 + (4 + 6) - 8. Distributive property allows us to not have to do parenthesis first by multiplying the number (and its sign) outside the parenthesis by everything inside the parenthesis. a(b + c) = a x b + a x c is an example. Find another example.
A) 5 x 1 = 5 B) 2(3 + 4) = 6 + 8 C) 6 x 5 x 2 = 2 x 5 x 6 D) (2 + 4) + 6 = 2 + (4 + 6) - 9. 2(6 + 1) = 2 x 6 + 2 x 1 is an example of which property.
A) Distributive Property B) Identity Property C) Commutative Property D) Associative Property - 10. 1 x 4 x 5 = 5 x 4 x 1 is an example of which property.
A) Associative Property B) Identity Property C) Commutative Property D) Distributive Property |
