The Frames in the PowerClix® system come in several translucent colors that have different geometric shapes allowing for endless creativity. The pieces can be use to make both 2D and 3D constructions as they are designed to integrate flawlessly. Children can create shapes by visually making wireframe models of an underlying structure, then building it with the magnetic frame shapes. The PowerClix® system is an excellent teaching tool for geometry, showing kids how 3-Dimensional shapes look and feel to the touch. Being able to actually build and see a geometrical shape, helps children get a better understanding of the concept. The frames in the PowerClix® system are designed to integrate between Solids and Organics. This flawless integration offers countless possibilities for building all types of structures, giving children hours of imaginative play while learning at the same time. This set includes 48 pieces.
