Counting flat faces, straight edges, and corners

Math - Grade 2-3

Instructions: Read each problem carefully. Count flat faces, straight edges, and vertices, which are corners. Show your work in the space provided.
  1. 1
    A colorful cube with square faces shown.

    A cube has 6 flat square faces. How many faces does a cube have?

  2. 2
    A cube with its corners marked by dots.

    Count the vertices on a cube. Remember that vertices are corners.

  3. 3
    A colorful cereal-box-shaped rectangular prism.

    A rectangular prism is shaped like a cereal box. How many faces does it have?

  4. 4
    A rectangular prism with its edges highlighted.

    How many edges does a rectangular prism have?

  5. 5
    A square pyramid with a square base and triangular sides.

    A square pyramid has 1 square face on the bottom and 4 triangle faces on the sides. How many faces does it have in all?

  6. 6
    A square pyramid with its vertices marked by dots.

    How many vertices does a square pyramid have?

  7. 7
    A triangular prism with triangle ends and rectangle sides.

    A triangular prism has 2 triangle faces and 3 rectangle faces. How many faces does it have?

  8. 8
    A triangular prism with vertices marked on both triangle ends.

    A triangular prism has 6 vertices. If 3 vertices are on one triangle end, how many vertices are on the other triangle end?

  9. 9
    A cube and a rectangular prism shown side by side.

    A cube and a rectangular prism both have the same number of faces. How many faces do they each have?

  10. 10
    A cube and square pyramid with vertices marked.

    Which shape has more vertices: a cube or a square pyramid?

  11. 11
    A triangular pyramid with triangular faces.

    Look at a shape with 4 triangle faces and no square or rectangle faces. This shape is a triangular pyramid. How many faces does it have?

  12. 12
    A cube and triangular pyramid with corners marked.

    A triangular pyramid has 4 vertices. How many fewer vertices does it have than a cube?

  13. 13
    A cube-like prism and a square pyramid for comparison.

    A solid shape has 6 faces, 12 edges, and 8 vertices. Is it more like a cube or a square pyramid?

  14. 14
    A square pyramid with faces colored and vertices marked.

    Maya counts 5 faces and 5 vertices on a shape. She thinks the shape is a square pyramid. Is Maya correct?

  15. 15
    A cube and a rectangular prism with vertices marked.

    Draw or name one 3D shape that has 8 vertices. Then write how many faces it has.
