PowerClix® Solids have colorful, solid translucent plastics and geometric shapes that allow for open-ended, creativity-inspiring constructions. Solids are for teaching and exploring solid geometry. Created for the younger builder, both 2D and 3D forms may be built by distilling the structures down to simple solid geometric shapes, furthering their understanding of how mass and volume are used to model an object. Solids are designed to integrate flawlessly with Frames and Organics, all part of the PowerClix® System.
