Instructional Ideas

  • Lead a discussion on the minimum and maximum number of sides possible for slices of different solids
  • Provide a solid and have the class find all its nets

Classroom Considerations

  • Requires pupils to know the names of different 2-D shapes
  • This video is hosted on YouTube

Pros

  • Uses colors to help identify the faces of solids in the net
  • Contains a link to more cross-section and net resources

Cons

  • None
