Number Line

This is a visual aid designed to be projected onto a whiteboard for whole class exposition.

For the teaching of decimal fractions see the Decimals Line.

Change the numbers displayed on the number line by using the dropdown boxes above. The two arrows are available to drag up to the number line to show certain values.

This number line can help you explain directed number arithmetic. For example to show the calculation 6 - 10 you could start by moving the blue arrow to show positive six. Next use the red arrow to move ten units to the left (equivalent to minus ten) ending at minus four.

To show the calculation - 4 - - 7 begin with the blue arrow at minus four. The red arrow can then show that subtracting negative seven equates to a move to the right ending at positive three.
