Step 8 Objective
Visualise and use 2-D representations of 3-D objects; analyse 3-D shapes through 2-D projections, including plans and elevations.
- Examples of what pupils should
know and be able to do - Probing questions
- What if pupils find
this a barrier?
Probing questions
Starting from a 2-D net of a 3-D shape, how many faces will the 3-D shape have? How do you know?
What will be opposite this face in the 3-D shape? How do you know?
Which side will this side join to make an edge? How do you know?
How would you go about drawing the plan and elevation for the 3-D shape you could make from this net?
Given this plan and elevation, what can you know for sure about the 3-D object they represent? What can you not be sure about?
