Nets This is a drawing of a cubic box without a lid. GM2.3 Core Starter This is a drawing of a cubic box without a lid. Draw all the different nets you can for the box. Here is one to start with. Try to find a systematic method of searching for all the possible nets. Preamble This activity reviews work on nets, and should highlight any grave misconceptions. Some pupils may need reminding as to what constitutes a net. Ensure that pupils have all eight nets before attempting to find any patterns. Possible content Drawing nets; geometrical pattern-spotting; systematic working. Resources Squared paper to aid the drawing of nets. Solution/Notes Eight distinct nets are possible. The easiest systematic approach is probably to consider the longest row of squares in the net. Start with those containing a row of 4 squares; then those with a row of 3 squares; finally, those whose longest row is 2 squares long.
