MegaPro Calculator 5000

by

MegaPro has turned the common hand calculator into a visual math illustrator. This easy-to-use app provides a natural middle step between the world of mathematical manipulatives and paper-based hand calculation. Whole numbers as large as nine million can be visualized, as well as added, subtracted and multiplied. All interactions have a clear correspondence to traditional methods of hand calculation on paper.

MegaPro’s utility as a visual aid for parents and teachers is unquestionable. But beyond that, this remarkable app also creates new possibilities for how we teach arithmetic to children. By turning arithmetic into a machine that children can examine, MegaPro opens up a world of possibility for engaging children in a collaborative investigation of the mechanisms of arithmetic.
