This can be used to demonstrate the existence of decimal numbers. Prerequisite is that learners have some prior understanding of representation of whole numbers on a number line

By zooming in, the decimals in tenths, hundredths, and up to thousandths are revealed around the region on the number line where the point A is placed. You can click on the point A and drag the point to change its position, with your mouse.

Prepare your own lesson plan to guide the students exploration. I do appreciate feedback for further improvement of this resource.

Instructions:

Numbers can be represented on a number line. Besides whole numbers 1, 2, 3 and so on, decimal numbers also exist between 1 and 2.

Use Zoom In (middle scroll mouse button) to see what numbers there are.

You can click on the point A and drag the point to change its position, with your mouse. So try to locate 1.1, 1.25, 1.585

Do you think 1.5859 exist? Show your teacher where you think that might be on the number line.
