The STEAM Stack and Build Kit brings together children’s schematic interests with loose parts play. The kit enables children to build large and small scale castles; dens and imaginative locations; and even different modes of transportation such as trucks, cars, airplanes and trains. It further supports children’s fine and gross motor development as they manipulate the connectors to attach and fix pieces in play. This set lets children construct without limits from laboratories to mud kitchens. All this while developing collaboration, motor, mathematical thinking, creativity, and problem-solving skills.
