Last Updated 8th May 2022 This set of powerpoints contain example problem pairs for topics across the GCSE / IGCSE syllabus, grouped by Algebra, Geometry, Number, and Probability and Statistics. I have built these up over time and hope it will save teachers some time in writing questions into slides. It is, and should remain, a FREE resource. All sources of images/diagrams, where possible, have had permission granted by the authors to be used and have been credited in the slides. A special thanks to Corbettmaths and DESMOS used for many slides. There will inevitably be some mistakes.
