Dynamic geometry software can transform the teaching of mathematical concepts by engaging pupils in interactive demonstrations, constructions and explorations. It can also stimulate mathematical discussions and encourage mathematical thinking among pupils. In the first session, a Year 8 class is exploring how and why regular hexagons tessellate. They learn how to use the dynamic geometry software to create the hexagon in the first place, and then explore how to rotate their completed shape to create a tessellated pattern. Using the software is more convenient and accurate than using pencil and paper, so the pupils can spend more time discussing why it is that these shapes tessellate, and go on to investigate why some other shapes don't. The second session shows a Year 9 class using a grid of seven interlinked circles to explore and define the essential properties of 2D shapes.
