In a nutshell: Learn how to spot odd and even numbers and why they're useful.
## What Makes a Number Odd or Even?
Odd numbers can't be split into two equal groups, but even numbers can!
### How to Tell
- Even numbers end in 0, 2, 4, 6, 8.
- Odd numbers end in 1, 3, 5, 7, 9.
### Why Does It Matter?
Knowing if a number is odd or even helps with sharing and dividing things equally.
### Fun Activities
Try grouping toys or snacks into pairs and see which numbers are even or odd!
Examples
- 4 is even because it can be split into 2 and 2.
- 7 is odd because you can't split it into two equal groups.
