Pupils design a 2D net for a box, given a 3D picture of the box.
- National Curriculum levels 4 to 6
- 30 minutes to 1 hour
- Ruler and pencil; it may be useful to have spare copies of the worksheet available; scissors available but provide only on request
Key Processes involved
- Represent a 3D object in 2D.
- Visualise how the box will look when opened flat; draw their net accurately, joining faces appropriately and keeping the correct orientation of the pictures on the faces.
- Imagine the net folded up again (after drawing it) and locate a sufficient number of flaps so that faces may be joined together; ensure that glue flaps do not interfere with one another.
- Communicating and reflecting
- Draw the box design clearly and labelled
Check that pupils fully understand the task context before they begin, with points such as:
- You are asked to draw a net, in one piece, for a candle box.
- What will the box look like when it is assembled?
- What types of flaps will you need to include? Some are to be glued and some not; how will you tell which ones are which?
- What is important about the candle designs on the sides and top of the box?
Pupils may tackle this task in different ways, but they might be expected to:
- make 3D mathematical models by linking given faces or edges, and draw common 2D shapes in different orientations on grids
- recognise and use common 2D representations of 3D objects
