Stretch imaginations as high or far as students can build using corrugated cardboard shapes and metal fasteners. Inventors connect an assortment of reusable shapes, including triangles, circles, and squares, to test their endless imaginations against the physical limits of the world we live in. Challenge students to create simple machines, creatures, sculptures, or architecture and use the pieces repeatedly to iterate on initial designs. Individual kit includes pieces for 1-3 students. Class Kit includes enough for 20+ students.
