This presentation contains a whole lesson looking at the Poisson Distribution (18 slides), but there is enough material to spread over 2 lessons, depending on the amount of time you have per lesson for A-Level! It comes with excellent past exam questions with answers.
Specifically, this lesson is for teaching ... what is Poisson distribution and normal distribution are and how and when to use the normal distribution as an approximation and approximation using the Poisson distribution. I have used the PowerPoint slides to structure the lesson, and included plenty of examples etc... and I have found to be a great resource to help pupils understand and make excellent progress.
