Commutative Property
What is the commutative property of
3+8 ?
3+8=8+3
Round this number to the nearest tens.
8
10
Find the associative property for this problem.
4+(10+3)=17
(4+3)+10=17
or
(10+4)+3=17
Solve the subtraction problem.
42-36
6
Solve the addition problem
47 +58
105
213+56=269
56+213=269
Round this number to the nearest tens.
72
70
Solve the associative property of addition.
15+(4+10)=
29
90-82=

Solve the Problem
72+39=
111
Correct the mistake
14+4=41 so, 4+14+18
The sum for both problems should be 18.
14+4=18 so, 4+14=18
Round this number to nearest hundreds.
456
500
Fix the mistake.
12+(0+18)=12 So, 18+(12+0)=12
The answer should be 30
Solve the problem.
664-63=
601
Solve the problem.
209+318=
527
Fix the mistake.
24+(3+4)=31 so (24+3)+4=31
This is the Associative Property not the Commutative Property.
Estimate to the nearest tens.

What is the difference between the associative versus the commutative property of addition?
The associative property must have parenthesis ( ). The numbers inside of the ( ) must be added first.
The commutative property must have the addends switched around to find the sum.
