Even Numbers

An even number can be divided into pairs without any object left over.
Examples:

2, 4, 6, 8, 10, 12

Example with objects:
🍎🍎 🍎🍎 🍎🍎
There are 6 apples.
They can be put into pairs with none left over.
So 6 is an even number.
Even numbers usually end in:

0, 2, 4, 6 or 8

An odd number leaves one object without a partner when grouped in pairs.
Examples:

1, 3, 5, 7, 9, 11

Example:
🍊🍊 🍊🍊 🍊
There are 5 oranges.
One orange is left without a partner.
So 5 is an odd number.
Odd numbers usually end in:

1, 3, 5, 7 or 9

Examples

  • 12 – even
  • 17 – odd
  • 24 – even
  • 35 – odd
