Since 2017 I've produced a series of CPD sessions, each one covering an individual maths topic. I call this my 'Topics in Depth' project. These CPD sessions focus on curriculum, assessment, subject knowledge, pedagogy and resources.
Thanks to generous sponsorship from AQA, Craig Barton and I recently recorded a new set of Topics in Depth presentations. We released Area in Depth a couple of weeks ago - thanks for the lovely feedback on this. Today I have the pleasure of sharing Surds in Depth with you.
If you're a maths teacher with a spare hour, please watch this! I hope you find it enjoyable and helpful.
