Introduction
Even and odd numbers are an essential part of mathematics. They help us classify numbers into two groups based on their divisibility by 2. This lesson will introduce students to even and odd numbers, how to identify them, and how to use them effectively in everyday life.
Numbers are infinite—they begin from 1 and go on forever into what we call “Infinity.”

Understanding Even and Odd Numbers
Even Numbers
- A number is even if it can be divided by 2 without leaving a remainder.
- Examples: 2, 4, 6, 8, 10, 12…
- Even numbers often appear in pairs or groups that can be split evenly.
- Fun Tip: Even numbers always end in 0, 2, 4, 6, or 8.
Odd Numbers
- A number is odd if it cannot be divided by 2 evenly (it leaves a remainder of 1).
- Examples: 1, 3, 5, 7, 9, 11…
- Odd numbers often appear in groups where one element is left unpaired.
- Fun Tip: Odd numbers always end in 1, 3, 5, 7, or 9.
