Maths specialist and teacher Carol Knights demonstrates how Dynamic Geometry software can transform the teaching of mathematical concepts by engaging pupils in interactive demonstrations, constructions and explorations. She shows a demonstration and proof of the sum of the angles in a triangle, an interactive number line, and how to use the software to explore reflections, rotations and symmetry. She shows how to do some classic geometrical constructions and a visual illustration of Pythagorean Theorem. Finally, she shows how the software can be used to create graphs and we see this facility used by a class of year 7s to explore the properties of straight line graphs.
