Teaching direct proportion can be confusing for students. I have carefully thought about the introduction to this and have broken it down into manageable chunks. The lesson leads up to the complex questions (i.e. x is directly proportional to y). The new GCSE (1-9) requires students to draw the proportions on graphs and use them. I have added 6 questions on this. Answers and solutions are available for all work set. Includes detailed step by step explanations, my students really benefited from this. PowerPoint presentation and ActivInspire flipchart available.
