| This ITP generates a number line. Two markers with numbered boxes can be moved along the number line. Depending on the order of the two markers you can show the sum and difference between the two numbers and the calculation represented. The maximum and minimum values on the number lines can be altered and the numbered intervals can be hidden and revealed.

| ITP Guide also available as a word document.
