About Number Hop
Number Hop builds number sense, one of the most useful maths skills of all. A number appears; tap the log where you think it belongs and Hopper the frog jumps there. The closer you are, the more flies Hopper catches.
Start with 0 to 10, then 20, 100 and 1,000, first with tick marks to help and then without. Fraction Falls brings halves, quarters, thirds and decimals between 0 and 1, and Frosty Fjord goes below zero. Every few hops the question turns around: the fly is on the line and you say which number it is.
A hint marks the middle of the line, which is the best place to start thinking. Flies buy hats for Hopper: a cap, a crown, sunglasses, a wizard hat and more. Your progress is saved on this device.
