A Clean Interface With Intuitive View of Arithmetic

Number Line, by the Math Learning Center
Virtual number line is clean and pretty but not terribly useful
Pros: Organizes and presents number-line exercises in a very clear, distinct way with nice colors, annotations, and equation entry tools.
Cons: It's hard to think of where it would work better than old-fashioned hand-drawn number lines.
Bottom Line: If you need a cleaner way to show number lines or you like the app's number-hiding tool, this could be useful. For most, it's probably not necessary.
