Which shapes did you make?
Using straws or ice-cream sticks and clay or play dough, students can make various 3D shapes including:
Cubes Tetrahedrons Pyramids Prisms Octahedrons Other polyhedra
The shapes made depend on how many edges are used and how they are connected at vertices.
Explanation
The chapter suggests building 3D shapes using simple materials. Students can create various polyhedra by connecting edges (straws/sticks) at vertices (clay/dough). This hands-on activity helps students understand the structure of 3D shapes.
Solution Steps
Use straws or ice-cream sticks and clay or play dough as materials.
Construct various 3D shapes: cubes, tetrahedrons, pyramids, prisms, octahedrons, and other polyhedra.
The shapes depend on the number of edges and how they connect at vertices.
