Experience engineering challenges, ratio exploration and gear connections in a play-based environment using the digitally inspired IO Blocks and gears of the IO Blocks Tabletop System. Square, double-sided, puzzle-like base pieces interlock in a variety of ways to create a 2D or 3D base that supports IO Blocks and gears. Children can build both horizontally and vertically using the base pieces. Little IO people with unique accessories and IO cows add an element of fun and imaginative play. Easily incorporate with your existing IO Blocks sets for endless build possibilities. Includes activity cards. Ages 3+.
