MAFS.1.OA.1.2 (DOK 2) Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. [Application] Use objects, drawings, and equations with a symbol for the unknown number to represent the problem Know how to add three whole numbers whose sum is less than or equal to 20 Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20
MAFS.1.OA.2.3 (DOK 2) Apply properties of operations as strategies to add and subtract. Examples: If = 11 is known, then = 11 is also known. (Commutative property of addition.) To add , the second two numbers can be added to make a ten, so = = 12. (Associative property of addition.) [Conceptual Understanding]
