Arithmetic through geometry, built so the mathematics is the thing you do rather than the thing you answer afterwards. Box Balance teaches equation solving by making you do the same operation to both sides until the unknown stands alone. Fold asks you to fold a flat net into a cube in your head and say which faces end up opposite each other. Estimate Engine rewards a good approximation rather than an exact answer, which is the skill people actually use. Number sense, fractions, place value, coordinates, angles and mental estimation are all covered.
