Contributor: Samantha Penna. Lesson ID: 11790

You see numbers all the time! Numbers aren't all the same - some are even, some are odd. Do you know the difference? It's not odd if you don't; it's even fun to learn about them with games and songs!

Numbers are everywhere!

Can you think of some places you see numbers during the day? Tell your parent or teacher.

Numbers can be seen on clocks, remote controls, phones, road signs, and many other places. They are an important part of life!

This lesson is all about telling the difference between even numbers and odd numbers.

First you will learn about even numbers. Even numbers all have something in common. If you are looking at one-digit numbers, the even numbers are:

0 2 4 6 8

Can you say those numbers aloud? Tell your parent or teacher.

Zero, two, four, six, and eight are all even numbers.

If you look at two-digit or higher numbers, there is a special way to tell if the number is even. If you are working with a number that has two digits or more, only focus on the number in the ones column. This number tells you whether a number is odd or even. If the number ends with a 0, 2, 4, 6, or 8, it is an even number. Look at the examples of the even numbers below. All of these numbers end in 0, 2, 4, 6, or 8:

10 22 34 46 58 62 70 88 94

Can you say those numbers aloud to your parent or teacher?

Those are all even numbers. All even numbers are divisible by 2.


Now, you will learn about odd numbers. Single-digit odd numbers include:

1 3 5 7 9

Can you say those numbers aloud to your parent or teacher?

Great work! All of those numbers are odd numbers. Two-digit or higher odd numbers always end with a 1, 3, 5, 7, or 9. Remember, in order for a two-digit number to be an odd number, it needs to end with one of those numbers. Take a look at the two-digit odd numbers below. Unlike even numbers, odd numbers are not divisible by 2. If you were to divide by 2, you would always have 1 left over:

11 23 35 47 59 61 73 85 97

All of the numbers above are odd numbers. Can you read them aloud to your parent or teacher?

Excellent work! You can tell the difference between even and odd numbers.

Before moving on to the Got It? section, tell your parent or teacher what one-digit numbers are even numbers.
