One thing I’ve noticed about teaching maths is that creating good resources can take almost as much thought as planning the lesson itself. A worksheet might look great, but if the questions aren’t well matched to the specification, don’t provide enough variety, or don’t help students understand their mistakes, it may not have the impact we hoped for. For tutors teaching GCSE or IGCSE maths, I’m curious: What do you look for when deciding whether a maths resource is genuinely worth using with your students? Is it accuracy, question variety, difficulty progression, time saved, exam relevance, or something else? And what’s one resource or tool you’ve found that has genuinely made your tutoring easier?
