Which property is being
shown or described?
91 + 113 + 42 = 42 + 113 + 91
Adding zero (0) to a number does not change the
sum (the answer to an addition problem).
112 + 0 = 112
2 + (11 + 23) = (2 + 11) + 23
Changing the order of the numbers that you add
does not change the sum. You can add numbers
in any order.
Changing the grouping of the numbers does not
change the sum in an addition problem.
Wednesday:

(5 + 4) + 3 = 5 + (4 + 3)
Identity Property
7+0=7
Commutative Property
3 + 12 = 12 + 3
3 + (6 + 2) = _________________________________
2. Commutative:
3. Identity:
Associative Property
4 + 8 = ________________________
112 - 0 = _________________________
4. Commutative: 456 + 897 = ____________________________
5. Identity: 34 + 0 = ___________________________
