## Explore 3D Shapes and Their Properties

Once your students can successfully recognise and name the most common 3D objects, it’s time to move on to teaching them the properties (features) of these geometric figures.

This worksheet requires students to record the number of faces, edges and vertices, or the number of flat and curved surfaces, for some of the most common 3D objects. The objects included on the worksheet are:

• Cube
• Pyramid
• Rectangular prism
• Cylinder
• Sphere
• Cone

## A Note About Cones and Cylinders

Within this resource, you will notice the following properties are attributed to cones and cylinders:

• Cones – 1 flat surface, 1 curved surface
• Cylinders – 2 flat surfaces, 1 curved surface

In geometry, the following definitions apply to faces, edges and vertices:

• Face – A flat surface with straight edges.
• Edge – A straight line formed by two faces meeting.
• Vertex – The point where two or more edges meet.

According to these definitions, a cone has no faces, edges or vertices. It has one flat surface, one curved surface and one apex.

Similarly, according to these definitions, a cylinder has no faces, edges or vertices. It has two flat surfaces and one curved surface.
