This is a lesson is on teaching the binomial expansion. It comes with an excellent investigation to begin with (and interesting starter) to allow pupils to self discover Pascal's triangle. This leads into some excellent teaching slides to help pupils really understand the process of expansion. It also comes with some excellent examples, a worksheet of old exam questions with answers and plenary.
This is a thorough PowerPoint of 24 slides and this is probably enough material for a double lesson, which is normally the length of time that I need to teach this topic.
