Even and Odd Numbers for Kids: Pairs and the Last Digit Trick (Grade 2 Math)

Hi, I'm Luna from DoodleBeez. Today we are learning about even and odd numbers. Every number is one or the other, and there is an easy way to tell.

Even numbers can be shared into pairs with nothing left over. Here are six socks. Let's put them in pairs. One pair, two pairs, three pairs. Nothing is left over, so six is even.

Odd numbers always have one left over. Here are seven socks. One pair, two pairs, three pairs, and one sock all alone with no partner. So seven is odd.

Here is the quick trick for any number, even a huge one. Just look at the last digit. If it ends in zero, two, four, six or eight, it is even. If it ends in one, three, five, seven or nine, it is odd.

Let's try it. Three hundred and forty six. The last digit is six, so it is even. Nine hundred and twenty one. The last digit is one, so it is odd.

Now it's your turn. Is fifteen even or odd? Pause and think. Fifteen ends in five, so it is odd. And twenty eight? It ends in eight, so it is even.

Great job! Remember, even numbers make pairs with none left over, odd numbers have one left over, and the last digit tells you which. Practice even and odd in the Math Lab at doodlebeez.com. See you next time!
