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?
Use the interactivity to make this Islamic star and cross design. Can you produce a tessellation of regular octagons with two different types of triangle?
Investigate these hexagons drawn from different sized equilateral triangles.
This activity challenges you to make collections of shapes. Can you give your collection a name?
