On Saturday 4th July, I was kindly invited to give the opening address at the wonderful Edexcel Maths Conference in Warwick. The title of my talk was “The 5 most interesting misconceptions in mathematics”. Quite a few people asked me for a copy, so here it is, along with some screen shots.

And as a disclaimer, these are purely my own choices for what I considered to be interesting misconceptions – ones that in 10 years of teaching I have not necessarily emphasised, but I certainly will from now on.

All the lovely sunburst diagrams, come courtesy of our Data pageon Diagnostic Questions. Please have a play around – I promise you will not be disappointed! :-)

Here is the link to download the PowerPoint.

And here are some screen shots:
