Odd and Even Numbers
Even numbers can be divided evenly into 2 groups with no left over pieces.

They always end in 0, 2, 4, 6, or 8.   Odd numbers can’t be evenly divided evenly into 2 groups and will always have a remainder when split into 2 groups.

They always end in 1, 3, 5, 7, or 9.   Odd and even numbers alternate with each other.

An odd number is always followed by an even number. ## Odd and Even Number Rules
