Subtraction Using NumLine Lite APK

This new updated version provides a full screen display regardless of the size of the devices.

This program uses the number line to help the student understand subtraction. For instance, if the problem is 9 - 3 = ?, the program will tell the student to click on the first number (9) and a yellow bar will highlight all the spaces on the number line up to the 9. The program will then tell the student to click on each of the next 3 numbers to the left of the 9. These 3 spaces will be highlighted in red, and will show that the answer to the problem is 6. After clicking on these two numbers, the student will be told to click on the Done button. This program subtracts only single-digit numbers.
