Standard Identifier: K.OA.1
Grade:
K
Domain:
Operations and Algebraic Thinking
Cluster:
Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.
Standard:
Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
Footnote:
Drawings need not show details, but should show the mathematics in the problem. (This applies wherever drawings are mentioned in the Standards.)

Cluster:
Represent and solve problems involving addition and subtraction.
Standard:
Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.

Standard Identifier: 1.OA.3
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.
