2.OA.C.3

**2.OA.C.3**: 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.

What you'll learn

Determine whether a group of up to 20 objects has an odd or even number of members by pairing the objects and checking whether any object is left over
Determine whether a number (up to 20) is odd or even by skip counting by 2s and checking whether the number appears in the count sequence
Identify the pattern that even numbers end in 0, 2, 4, 6, or 8 and odd numbers end in 1, 3, 5, 7, or 9
Write an equation to express an even number as a sum of two equal addends (e.g., 8 = 4 + 4, 12 = 6 + 6)
Explain in their own words why a number is even or odd, using evidence from pairing, skip counting, or an equation
