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.
