Distributive Property
Which equation shows the commutative property of addition?
a. 8 + 9 = 9 + 8
b. 3(25) = 3(20)+ 3(5)
c. 18x3 = 3x18
d. 7+(3+2)= (7+3)+2
a. 8+9 = 9+8
Which equation shows the associative property of addition?
a. (7+9)+2 = 7+(9+2)
b. (1 + 8) = (2) + 7
c. 7 + (9) = 9 + 7
d. 1 + 0 = 1
a. (7+9)+2 = 7+(9+2)

6 + 10 = 16
A property where you break down the number into smaller parts or place value, multiply each part separately and then add.
Distributive Property
2+13+6 = 13 + 2+6
Which equation shows the commutative property of multiplication?
a. 6+2 = 2+6
b. 4+(2+8) = (4+2)+8
c. (12x9 )x2= 12x(9x2)
d. (3x4) x 10 = (4x3) x 10
d. (3x4) x 10 = (4x3) x 10
Which equation shows the associative property of multiplication?
a. 8+(2+3)=(8+2)+3
b. 4(2+5)= 4(2)+ 4(5)
c. (18x3)x7 = 18x(3x7)
d. 5+9 =9+5
c. (18x3)x7= 18x(3x7)
Find the product using the distributive property:
9 x (13)
9 x (13)= 9 x(10)+ 9 x(3)
90+27= 117
A property, when adding or multiplying, where you change the grouping and still get the same result
Associative Property
6x(20)+ 6x(3)= 6x(23)
Distributive Property
Use the commutative property to determine if the equation below is equal or not equal:
13x5x2 = 2x13x5
Equal
Using the associative property, are these two number sentences equal or not equal
(2+3)+9 = 2(3+2)
Not equal
Find the product using the distributive property:
8 x (143)
8 x (100 + 40 + 3)
8 x (100)= 800
8 x (40) = 320
8 X 3 = 24
800 + 320 + 24 = 1144
