Estimate the Position of Numbers on a Vertical Number line

When we estimate, we guess but with some calculation. 

In this worksheet, you must estimate which number the arrow is pointing to on a vertical number line.

Example

Estimate which number the arrow is pointing to.

Answer

In your mind, picture where the halfway number 5 is.

In your mind, picture the small number divisions between 0, 5 and 10.

The arrow is pointing to one mark before 5, which is 4.

Is that the number you thought it would be?

Let's have a go at some questions now.
