# Practical details

Suitability
National Curriculum levels 6 to 7
Time
30 minutes to 1 hour
Resources
Ruler, pencil, and paper; scissors available (if requested by pupils)

# Key Processes involved

Representing
Identify the significant parts of the bottle to measure and formulate a suitable box design
Analysing
Translate the appropriate measurements to a net
Interpreting and evaluating
After designing the net, imagine it folded
Communicating and reflecting
Draw the box design clearly and label it well

# Teacher guidance

Check that pupils understand the context, for example, you could bring in a bottle to help them visualise the problem. It may also be helpful to have some rectangular boxes folded from nets. Comments could be as follows:

• The diagrams on your sheet show two views of the bottle drawn accurately full size
• The left hand diagram shows a view of the bottle from the top.
• What is the diameter of the cap?
• The diagram shows the bottle from one side. Why is there no diagram of the bottle from another side?
• What is a net?

Pupils can tackle this task in different ways, but they might be expected to:

• recognise and use common 2D representations of 3D objects
