1.OA.3 (Mathematics)
Standard Identifier:
1.OA.3
Content Area:
Mathematics
Grade:
1
Domain:
Operations and Algebraic Thinking
Cluster:
Understand and apply properties of operations and the relationship between addition and subtraction.
Standard:
Apply properties of operations as strategies to add and subtract. Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
Footnote:
Students need not use formal terms for these properties.
