This is a whole lesson (30 sides) doing an investigation, which is fun and to self-discover what the binomial distribution is and introduces the whole topic. It also looks at the notation involved and putting the formula into a general form. This is a fantastic foundation for the next lesson.
I like teaching this lesson and every time I have taught it, the pupils love it and has been a really successful way of getting a deep level of understanding. This comes as one of three lessons on the binomial lesson and 4 if you include using the normal approximation.
