The ones digit tells you
A number is even if its last digit is 0, 2, 4, 6 or 8, and odd if it ends in 1, 3, 5, 7 or 9. Once kids discover this, try a sheet with numbers up to 999 and watch their confidence grow.
Make it hands-on
For younger children, have them pair up counters for the first few numbers. If one is left over, the number is odd.
Make it a timed challenge
Put a visual classroom timer on the board and see how many problems students can finish before the time runs out. Print a new version tomorrow and try to beat the score.
