Following the Pearson Edexcel GCSE SOW for Higher students, Unit 15 - Equations & Graphs. Simultaneous Equations, Graphs of Inequalities, Quadratic Graphs, Expanding 3 Brackets, Cubic Graphs, Iteration (Trial & Improvement). Each PowerPoint is a full lesson including starter, examples, questions and plenary. The retrieval starter will link to the prior lessons here and in prior units I’ve uploaded. Credits to Mr Barton, Corbett maths, drfrostmaths and others from whom i have sourced some questions and slides. Some are my own too.
