KS3/4 Maths - Demonstrating Dynamic Geometry

Maths specialist and teacher Carol Knights demonstrates how dynamic geometry software can transform the teaching of mathematical concepts. Pupils can be engaged through interactive demonstrations, constructions and explorations.

Carol 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 Pythagoras' theorem.

Finally, she shows how the software can be used to create graphs and we see this facility used by a Year 7 class to explore the properties of straight line graphs.
