Show an eight-year-old the number 395,237 and ask whether it is even. Many will start to count, or freeze in front of six digits. This 3rd grade even or odd numbers worksheet teaches a shortcut that works for any size. A note at the top gives the rule: even numbers end in 0, 2, 4, 6 or 8, and odd numbers end in 1, 3, 5, 7 or 9. Below it, thirteen numbers follow, from 500 and 681 up to 267,980 and 395,237. For each one, your child looks only at the ones digit and ticks odd or even. A second page gives the answer key.
