Identifying even and odd numbers is an important skill that children will need throughout their math education. This skill will help prepare them to learn division, prime numbers, and even square roots. We define an even number as any integer divisible by two with no remainders. This means that the number can be divided into pairs or two equal groups with no leftovers. The numbers 2, 4, 6, 8, and 10 are all even numbers. An odd number is not divisible evenly by two. An odd number cannot be divided into pairs or two equal groups without leftovers. The numbers 1, 3, 5, 7, and 9 are all odd numbers.
