Activity
Identifying objects that are 1 inch & 1 foot.
![activity](https://www.turito.com/learn-internal/wp-content/uploads/2022/09/image-6110-1024x377.png)
Answer:
Objects that are about one thumb:
- Eraser
- Chalk piece
- Switch
A thumb is about 1 inch long.
Objects that are about the same length from your elbow to your fingers:
- Book
- Globe
- Files
- Charts
The length from your elbow to your fingers is about 1 foot long.
Estimating the objects that are about few inches long
Some paper clips are about 1 inch long.
1 inch in short is written as 1 in.

Now, let us estimate the length of the other objects by using a small paper clip.

Estimating the objects that are about few feet long
The book is about 1 foot long.
1 foot in short is written as 1 ft.

Estimating the objects that are about few yards long
A baseball bat is about 1 yard long.
1 yard in short is written as 1 yd.
