Identifying 3-D Figures
(and their attributes)
This page identifies some of the basic 3-D figures we study in 4th grade. Most importantly, students need to know how to count the edges, faces, and vertices of a 3-D figure. They also need to know how to match the figures with their corresponding nets. The edge of a figure is the straight lines that follow the sides. The faces are the flat surfaces of the figures. The vertex is the point where two edges meet. A net is the flattened-out representation of a 3-D shape.
Shapes (clockwise from the top right corner by their nets):
1. Hexagonal Prism (18 edges, 8 faces, 12 vertices)
2. Cylinder (no edges, 2 faces, no vertex)
3. Cone ( no edges, 1 face, no vertex)
4. Triangular Pyramid (6 edges, 4 faces, 4 vertices)
5. Rectangular Prism (12 edges, 6 faces, 8 vertices)
6. Square Pyramid (8 edges, 5 faces, 5 vertices)
7. Triangular Prism (9 edges, 5 faces, 6 vertices)
8. Cube (12 edges, 6 faces, 8 vertices)
* A sphere is also a 3-D shape with no edges, faces, or vertices.
