BIG IDEA 1: Develop understandings of addition and subtraction strategies for basic addition facts and related subtraction facts.

BENCHMARK CODE

BENCHMARK

MA.1.A.1.1

Model addition and subtraction situations using the concepts of “part-whole,” “adding to,” “taking away from,” “comparing,” and “missing addend.”

MA.1.A.1.2

Identify, describe, and apply addition and subtraction as inverse operations.

MA.1.A.1.3

Create and use increasingly sophisticated strategies, and use properties such as Commutative, Associative and Additive Identity, to add whole numbers.

MA.1.A.1.4

Use counting strategies, number patterns, and models as a means for solving basic addition and subtraction fact problems.

BIG IDEA 2: Develop an understanding of whole number relationships, including grouping by tens and ones.

BENCHMARK CODE

BENCHMARK CODE

BENCHMARK

MA.1.G.3.1

Use appropriate vocabulary to compare shapes according to attributes and properties such as number and lengths of sides, and number of vertices.

MA.1.G.3.2
