Frogs and Toads


Frogs can only move right, or down, and toads can only move left, or up. Can you exchange all the frogs and toads? Can you create a formula for the fewest number of moves? This deceptively simple puzzle starts with a row of frogs and toads, then advances to a grid. It can be played with manipulatives, online, or with people to provide an engaging, cooperative activity for all ages.
