2.OA.C.3 (Operations and Algebraic Thinking): Tell whether a group of up to 20 objects has an even or odd number.
About this standard
Second graders decide whether a group of up to 20 objects is odd or even, by pairing objects or counting by 2s, and write an even number as a sum of two equal addends, like 8 = 4 + 4. Counting by twos on a hundred chart makes the even numbers easy to spot. Practice with Even or Odd? Pair the Dots and Skip Counting by 2s, 3s and 4s.
