Even and odd numbers
Introduction
Count the numbers from 1 to 10.

Divide the toys into two equal parts.
![ducks equal](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-7033-1024x728.png)
Here there are 6 toys. Now divide them into two parts.
![ducks](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-7034-1024x508.png)
Divide the toys present in the image in two equal parts.
![comb](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/1-42-1024x329.png)
Here there are 3 combs. Now divide them into two parts.
![comb solution](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/2-37-1024x396.png)
Here, we cannot divide 3 combs into two equal parts because one comb is left.
Even numbers
The numbers which we can share evenly into two parts are known as even numbers.
![even numbers](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-7039-1024x403.png)
The numbers which have 0, 2, 4, 6, 8 in their ones place can be considered as even numbers.
We can divide even numbers into two equal parts.

Here there are four cubes in the top and, in the bottom, there are four cubes.
4 cubes + 4 cubes = 8 cubes
So, totally 8 cubes are there, and we know that 8 is an even number.
Example:
Write whether the number of objects present in the image is even or odd.
![blue orange](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-7037-1024x491.png)
Solution:
There are two objects present in the image. We can divide 2 into two equal parts. So, 2 is even.
Example:
Write whether the number is even or odd.
![12](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-7038.png)
Solution:
We can divide 12 into two equal parts.
6 + 6 = 12
So, 12 is even.
Example:
Write whether the number of cakes present in the image is even or odd.
![cake](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-7040-1024x218.png)
Solution:
There are four cakes present in the image. We can divide 4 in two equal parts. So, 4 is even.
Odd numbers
The numbers which we cannot share evenly in two parts are known as odd numbers.
![odd numbers](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/3-28-1024x353.png)
Here, we cannot divide 9 slices of pizza into equal two parts. So, 9 is an odd number.
The numbers which have 1, 3, 5, 7, 9 in their ones place can be considered as odd numbers.
Example:
Write whether the number of objects present in the image is even or odd.
![tablet ex](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-7041.png)
Solution:
Add the cubes to see whether the number is odd or even.
10 cubes + 9 cubes = 19 cubes
![tablet solution](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-7051.png)
We cannot divide 19 into two equal parts. So, 19 is an odd number.
Example:
Count the number of dots present in the below figure and write whether it’s an odd or even number.
![dot ex](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-7043-1024x442.png)
Solution:
There are nine objects present in the image. We cannot divide 9 into two equal parts.
![dot solution](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-7042-1024x323.png)
So, 9 is an odd number.
Example:
Write whether the number of objects present in the image is even or odd.
![ball](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-7044.png)
Solution:
There are three objects present in the image. We cannot divide 3 in two equal parts. So, 3 is odd.
Example:
Write whether the number of objects present in the image is even or odd.
![banana](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-7045-1024x235.png)
Solution:
There are seven objects present in the image. We cannot divide 7 into two equal parts. So, 7 is odd.
Example:
Write whether the number is even or odd.
![5](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/4-23.png)
Solution:
We cannot divide 5 in two equal parts. So, 5 is odd.
