Key Concepts
- Identify a group of objects that are even or odd
Introduction
Count the number of ice creams and tell if the number is even or odd.
![ice cream cone](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-6007.png)
There are seven ice creams. Divide 7 ice creams into pairs to identify whether the number 7 is even or odd.
![ice cream cone](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-6008.png)
We cannot divide 7 into 2s because one ice cream is left in the above image. So, seven is an odd number.
Can you count the number of apples present in the image?
![apple](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-5987-1024x215.png)
Yes, there are 8 apples, and we can divide 8 into 2s. So, 8 is an even number.
Even Numbers
The objects which we can count by 2s are known as even numbers.
Count the squares by 2s.
![Even Numbers](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-6009.png)
Here we can count the squares by 2s like 2, 4, 6, and 8. So, 2, 4, 6 and 8 are even numbers.
Example:
Write whether the number of objects present in the image is even or odd.
![Example:](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-5989-1024x253.png)
There are 8 objects present in the image. We can count the objects by 2s. So, 8 is even.
Example:
Write whether the number of objects present in the image is even or odd.
![Example: eyes](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-5988-1024x301.png)
Solution:
There are 10 objects present in the image. We can count the objects by 2s. So, 10 is even.
Example:
Write whether the number of objects present in the image is even or odd.
![Example: shoes](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-5991-1024x272.png)
Solution:
There are 16 objects present in the image. We can count the objects by 2s and here 8 pairs of shoes are there. So, 16 is an even number.
Example:
Write whether the number of objects present in the image is even or odd.
![Example:](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-5992-1024x253.png)
Solution:
There are 8 objects present in the image. We can count the objects by 2s. So, 8 is even.
Odd Numbers
The object which we cannot count by 2s is known as odd numbers.
Count the squares by 2s.
![Odd Numbers](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-5990-1024x335.png)
Here we cannot count by 2s. So, 3 and 5 are odd numbers.
Example:
Write whether the number of objects present in the image is even or odd.
![Example:](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-6010.png)
Solution:
There are 7 objects present in the image. We cannot count the objects by 2s. So, 7 is odd.
Example:
Write whether the number of objects present in the image is even or odd.
![Example: kids](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-6011.png)
Solution:
There are 5 objects present in the image. We cannot count the objects by 2s. So, 5 is odd.
Example:
Write whether the number of objects present in the image is even or odd.
![Example: circle](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-5993.png)
Solution:
There are 7 objects present in the image. We cannot count the objects by 2s. So, 7 is odd.
Example:
Write whether the number of objects present in the image is even or odd.
![Example: yellow circle](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-5994.png)
Solution:
There are 9 objects present in the image. We cannot count the objects by 2s. So, 9 is odd.
Example:
Write whether the number of objects present in the image is even or odd.
![Example: beanie](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-6012.png)
Solution:
There are 11 objects present in the image. We cannot count the objects by 2s. So, 11 is odd.
