# Math Practice Topic: Associative Property 1

 Description: Completion of equations that demonstrate the associative property with addition. For example, since 2 + (3 + 4) = 9, then (2 + 3) + 4 = 9.

## Sample Levels (out of 4)

Fill in the blanks.

1.
 (6 + 8) + 9 = 6 + (8 + 9) + 9 = 6 + =
2.
 (2 + 4) + 7 = 2 + (4 + 7) + 7 = 2 + =
3.
 (1 + 5) + 9 = 1 + (5 + 9) + 9 = 1 + =

Fill in the blanks.

 1 Rewrite the expression 2 + (4 + 8) using the associative property. 2 2 + (3 + 8) = ( + ) + 3 If 7 + (8 + 9) = 24, then what is (7 + 8) + 9? 4 Rewrite the expression 3 + (5 + 8) using the associative property.

Fill in the blanks.

1.
Which equation(s) show the associative property?
 (3 - 4) - 9 = 3 - (4 - 9)
 (1 + 8) + 9 = (1 + 8) + 9
 1 + (2 + 4) = (2 + 4) + 1
 (1 + 2) + 5 = 1 + (2 + 5)
 none of the above
2.
If 2 + (5 + 6) = (2 + x) + 6, then what is x?
3.
Which equation(s) show the associative property?
