This is a whole lesson on teaching frequency polygons. One of those exam questions that is done badly, simply because most people never teach a lesson on it. UPDATED. 15 slides.
It comes with a starter looking at discrete and continuous data and then a couple of activities, before getting to the heart of frequency polygons and then I have included a handout with real-life data and an activity based on that. The slide also comes with lesson objectives, answers and a quick plenary.
This is an excellent PPT to teach what can be a topic pupils slip up on.
