Materials needed:

• Geoboards
  
  
• Pattern Blocks
  
  
• Elastics
  
  
• Dot Paper
  
  

Find a partner to work with:

• Select two geoboards, some elastics, and some pattern blocks.
  
  
• One person will make one side of a shape on the geoboard and the other student has to make the other side of the shape so that it is symmetrical.
  
  
• Also try making symmetrical shapes using the pattern blocks.
  
  
• One student makes one side of a shape with the pattern blocks and the other student makes the other side so the shape is symmetrical.
  
  
• Record all your shapes by drawing then on the dot paper. Make sure you tell me where the line of symmetry is.
  
  
• Switch who goes first after each shape is completed.
  
  
• Make at least 5 symmetrical shapes using both the geoboards and the pattern blocks.
  
  
• Put the dot paper in your portfolio when you are done.
