Colourful Mathematics

DijkstraMy Year 12 students have just completed a Decision Mathematics mock examination. Preparing solutions to questions causing the most problems made me realise how often I use colour and highlighting in my explanations where I think this helps clarity. The following slideshow demonstrates the solution to a question on Dijkstra’s algorithm for finding shortest paths in network. I have changed colour once a new vertex has been chosen.

In case the Powerpoint is useful I have uploaded it here also: Dijkstra’s Algorithm – Colleen Young

See also Colour in Mathematics a presentation with examples showing how colour can help to make explanations clearer. I have many examples I have used for students of all ages, particularly in Algebra.
