This innovative folding geometric shape set is perfect for hands-on lessons in symmetry, Nets, perimeter, area, surface area, and volume. This 20 piece set includes 10 pieces of Geometric shapes "containers" with cover and lid. You can pour liquids or grains into them to compare the shapes.
Each shape has it own folding nets that fits perfectly into the container, allowing easy understanding of 3-dimensional Nets. Teachers can also use this to explain and proof the formulas for surface areas and volumes of 3-dimensional solids.
All the shapes share a common height of 10cm.
