- A child uses straws to join four triangles to a square base to make a triangular prism.
- A child uses a connector set to link four equal-length rods together at right angles, forming the base of a three-dimensional object.
- When asked to make a cube sticks, a child creates a shape with six faces, each one having four straight sides and four right angles.
Help your student become a(n) 3D Constructor of Shapes from Parts
Activities provide manipulatives such as straws or sticks for sides and chanelle sticks (small segments to fit into ends of straws) or globs of plasticine for angle "joiners." They ask children to build accurate models of various shapes, discussing for example, that six faces are needed to make cube, and that a sphere has no flat faces.
