Plus Plus builders are award winning, for so many good reasons! Our Big Building Set includes 10 baseplates and 400 vibrantly colored pieces that are perfectly sized for small hands, housed in a sturdy plastic storage tub. This STEAM set encourages free and explorative play while strengthening fine motor skills, inspires creativity, and challenges logic and problem solving skills - all without any screen time. The one simplistic shape of the Plus Plus builder produces endless possibilities, build flat to create a 2D picture, or build 3D shapes and structures - curves are even possible thanks to the unique design of this deceptively simple shape. This open ended building set can be used as a tool to illustrate the importance of patience, perseverance and determination - all while challenging children's imaginations!
