Common Core MATH 1 OA 3 Grade 1 Operations And Algebraic Thinking Understand And Apply Properties Of Operations And The Relationship Between Addition And SubtractionOperations And Algebraic Thinking: Understand And Apply Properties Of Operations And The Relationship Between Addition And Subtraction.
Apply properties of operations as strategies to add and subtract.3 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.
