Can you help the children in Mrs Trimmer's class make different
shapes out of a loop of string?
What shape is the overlap when you slide one of these shapes half way across another? Can you picture it in your head? Use the interactivity to check your visualisation.
This challenge invites you to create your own picture using just straight lines. Can you identify shapes with the same number of sides and decorate them in the same way?
What shape is made when you fold using this crease pattern? Can you make a ring design?
