2D & 3D Geometry with Interlocking Shapes

Interlocking geometric shapes (Geofix, Polydron, Polycontructo) help students to visualize and internalize key geometric concepts. Geometry and measurement become much more meaningful and exciting with these ready-to-use activities. Moving from 2D patterning to constructing complex 3D structures, each of the 15 activities features NCTM expectations, teaching instructions with extension activities, and reproducibles. Grades 3-6.
