The document defines key terms related to three-dimensional shapes like faces, edges, vertices, nets, plans and elevations. It provides examples of a plan view and front elevation of a house and prism. Students are then asked to draw a side elevation of a prism given its plan and front elevation, as well as draw the plans, front and side elevations of additional 3D shapes made of cubes.

3. A solid is a three-dimensional object that takes up space.
It has a width, a length and a height.
The surface of a 3D shape is called a face.
An edge joins two faces.
Edges meet at a vertex. A vertex is a corner of a
shape.

4. A net is a three dimensional object opened
out and laid flat.
A plan is the view looking down on a shape. It is a two-
dimensional drawing.
The elevation is the view looking at the front or side of
a shape.

5. A plan of a house
The house:

6. Now try these
1. Here is a plan and front elevation of a prism.
The front elevation shows the cross section of the prism.

7. (a) On the grid below, draw a side elevation of the prism.
(b) Draw a 3-D sketch of the prism.

9. Plan, front and side elevation
For each of these diagrams draw the plan, front and side elevation:

10. Plan, front and side elevation
Use the cubes to make up these shapes.

How many cubes do you use for each one?
For each of the shapes draw the plan, front and side elevation
