Factorial Teacher Resources

Entertain and grab your learners' attention with a short video clip that engagingly teaches the concept of a permutation and how a factorial is a wonderful shortcut for theoretical probability calculations.

Counting is not all it adds up to be — sometimes it involves multiplying. The activity introduces permutations and combinations as ways of counting, depending upon whether order is important. Pupils learn about factorials and the...

A week's worth of teaching on the Binomial Theorem. Lesson examples and a plethora of worksheets included. Learners find coefficients of specific terms within binomial expansions using notation of factorials and then apply these skills...

How many different ways can five people be arranged in any order in three chairs? Sal shows how combinations are different than permutations. He derives the formula for finding the combination without repetition.

Count the benefits of using the resource. The second installment of a 21-part module focuses on the fundamental counting principle to determine the number of outcomes in a sample space. It formalizes concepts of permutations and...

This video is an introduction to permutations. Sal shows  two different examples, defines the mathematical notation for permutations, and derives a formula for finding a permutation without repetition of choices. He tries to convey an...

What is the probability that two people out of thirty have the same birthday? Sal tackles this problem with his characteristic skill and casual attitude. Students will find his process easy to follow - and the solution to the problem...

It all comes back around in this video, where Sal explains the relationship between permutations, combinations, and probability. Going back to his example of a bag of coins, Sal determines the likelihood of getting different combinations...

Taking many of the concepts he has covered in the last few videos, including probability, combinations, and conditional probability, Sal uses the example of fair and unfair coins in a bag to show various probability problems. Students...
