What it does
Number track
is designed to help young learners develop a mental picture of whole numbers arranged in sequence on a track.

How to use it
When
Number track is first opened, you see at the top of the screen a track for displaying numbers. At this point, only the zero (0) is visible.

Click in any blank cell to see its numerical value. Positive numbers are displayed in blue and negative numbers in red.

Click on a displayed number to hide it.

Movement along the track is controlled by four sets of arrows. Two of the arrows go left and two go right. You have a choice of step-size of 1 and 10 in both directions.

The full range of the number track runs from -99 to 99.
