Tangrams 1

I have noticed that tangrams don't get much love in maths classrooms. They are seen as trivial and used for end of term activities. I believe there is so much more to explore.

There are lots of places in our curriculum where students need to be able to dissect shapes in different ways.

If we let children explore different ways of combining shapes, would this help them to find different ways of dividing up shapes later on?

My favourite prompts for tangrams include:
  • What shapes can you make with 2 triangles?
  • What shapes can you make with 3 triangles?
  • How many ways can you make a square?
  • What quadrilaterals can't you make with tangram pieces?
