About this worksheet
Groups of pictures to circle in pairs, then decide if the number is odd or even.
What kids practice
An even number can be split into pairs, or into two equal groups, with nothing left over. An odd number always has one left over. Every even number is a double, like 14 = 7 + 7, and every odd number is a double plus 1, like 15 = 7 + 7 + 1.
Watch for
- Thinking a number is odd because it looks big, or even because it "feels" round.
- Looking at the first digit instead of the last one in numbers like 12 or 21.
- Splitting an odd number into two equal parts and forgetting the 1 left over.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full odd and even guide for 2nd grade.
