These **'Just For Your Interest...'** posters explore the maths behind various common questions, often ones that I've pondered myself when I was a student. The A Level posters can all be found within the respective A Level PowerPoints, but the pdfs are included here for your printing convenience. Enjoy!

Here are the equivalent posters for younger students.

The following are a series of poster-form opinion pieces of various 'common teaching methods I don't like'. In each, they describe the typical method, my pedagogical misgivings with it, and my preferred method I use. Some I feel more strongly about than others, perhaps because there is some underlying mathematical flaw, or it prevents student misunderstanding, rather than just favouring another method because it's simpler. Obviously there's a degree of teacher subjectivity here!
