This presentation contains 2 or 3 whole lessons, depending on the amount of time you have per lesson for A-Level! Specifically this lesson is for teaching ... what is the binomial distribution, the criteria for using it, understanding where the formula comes from and ultimately using the formula to calculate probabilities. I have used the PowerPoint slides to structure the lesson, the first PPT takes pupils through an engaging investigation to really get to grips with what the binomial distribution is and beginning to use the formula. The second one even though shorter starts to look at the criteria for the binomial distribution and three examples of questions to go through. The first PPT. goes through a very specific and detailed explanation about the various parts/ bits of the formula and notation. I have found both these PPT's to be a very effective way of getting ALL pupils to understand the binomial distribution and feel confident in using the formula for questions.
