Identify Odd and Even numbers

Lesson
Decorative image

Whole numbers can be identified as odd or even.

Even numbers can be divided by two evenly. This means there are no remainders or splitting numbers in half. Odd numbers cannot be divided by two evenly; they have a remainder of 1.

Let's learn more about this by watching a video.

Remember!

If the number ends in 2, 4, 6, 8 or 0, it is even.

If it ends in 1, 3, 5, 7 or 9, it is odd.
