Create and use increasingly sophisticated strategies, and use properties such as Commutative, Associative and Additive Identity, to add whole numbers.
Remarks
Example: 2 + 3 = 5 and 3 + 2 = 5 (Commutative Property)Example: 2 + (3 + 1) = 6 and (2 + 3 ) + 1 = 6 (Associative Property)
Example: 7 + 8 = 7 + 7 + 1 (doubles + 1)
