Comparing faces, edges and vertices of 3-D shapes. Circle the shape with more faces. Circle the shape with more edges. Circle the shape with fewer vertices. Circle the shape with fewer edges.

Here are the shapes to circle for each section:

• Circle the shape with more faces.

  • Triangular pyramid: 4 faces
  • Rectangular prism: 6 faces
  • Pentagonal prism: 7 faces
  • Hexagonal prism: 8 faces The shape with the most faces is the hexagonal prism (the last shape on the right).

• Circle the shape with more edges.

  • Rectangular prism: 12 edges
  • Triangular prism: 9 edges
  • Triangular prism: 9 edges
  • Triangular pyramid: 6 edges The shape with the most edges is the rectangular prism (the first shape on the left).

• Circle the shape with fewer vertices.

  • Rectangular prism: 8 vertices
  • Square pyramid: 5 vertices
  • Pentagonal prism: 10 vertices
  • Rectangular prism: 8 vertices The shape with the fewest vertices is the square pyramid (the second shape from the left).

• Circle the shape with fewer edges.

  • Triangular pyramid: 6 edges
  • Rectangular prism: 12 edges
  • Octagonal prism: 24 edges
  • Triangular prism: 9 edges The shape with the fewest edges is the triangular pyramid (the first shape on the left).
