Domain Operations and Algebraic Thinking

Cluster Work with equal groups of objects to gain foundations for multiplication.

Standard Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.
