Odd and even numbers worksheets
Sorting numbers into odd and even is one of the first patterns children notice in counting. These free printable worksheets show a number up to twenty and ask a child to circle whether it is odd or even.
If they get stuck
Odd and even numbers
The answer key prints on a separate page.
What's on this sheet
Each question shows one number, and the child decides whether it splits into two equal groups or has one left over. Odd and even are mixed evenly across the page instead of leaning on one, and keeps every number at twenty or below so a child can check by pairing up counters when unsure.
Why this sheet works
Odd or even is a quick skill, so the page stays short — a handful of numbers is enough to make the pattern stick.
How this one works
One question from a sheet like this one, worked a step at a time — with a sentence saying what just happened and why.
