Ninja Hop: Number Line Quest

How to Play

Hopper the ninja frog solves word problems by leaping along a giant number line. Read the problem, take a quick guess where you will land, then hop with +1, +10 and +100 (or backwards to subtract) and tap LAND when you are standing on the answer. Six dojo worlds cover adding, subtracting, two-step problems, big numbers and missing parts, with a bar diagram and equation that fill in as you go. Fewer hops earn more stars, every fifth problem is a Sensei Challenge, and a hint flag appears if you get stuck.
