K.OA.2:
Operations And Algebraic Thinking
Understand Addition As Putting Together And Adding To, And Under- Stand Subtraction As Taking Apart And Taking From.
Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.
K.OA.3:
Operations And Algebraic Thinking
Understand Addition As Putting Together And Adding To, And Under- Stand Subtraction As Taking Apart And Taking From.
Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).
K.CC.6:
Counting And Cardinality
Compare Numbers.
Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies.1
