4 years & up. PowerClix® Naturals integrate elements of natural play and loose parts theory with the innovative STEM toy building platform of PowerClix®. With organic, neutral colors, Naturals encourages children to build architectural constructions using familiar shapes. In keeping with STEM toy attributes, PowerClix® magnetic building toys encourage children to think like engineers while having fun. Children can build unlimited 3D forms by visualizing the underlying design structure of an object, then creating a wireframe model of it using magnetic frames of geometric shapes. Naturals are designed to integrate flawlessly with all PowerClix® system sets. Organize and store PowerClix® pieces easily with the new metal plate built right into the packaging. The metal plate may be used as a building base as well.
