 Understand Addition As Putting Together And Adding To, And Under Stand Subtraction As Taking Apart And Taking From.
 State Standard:
 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).
