Who could have won the gold, silver and bronze medals? This activity is designed to be accessible to primary pupils at Key Stage 1.

Gives a basic introduction to combinations and permutations, highlighting the ideas of counting using replacement versus without replacement, and when order is important versus when order is not important.

Permutations are used in several detailed examples to demonstrate the method for finding the number of arrangements of events.

Based off of the hit television show NUMB3RS, this lesson is good practice for students who have already learned about permutations. U.S. Social Security Numbers are explained, and then students find the number of different SSNs which...

Practice using your graphing calculator for factorial, combination, and permutation expressions. If you get stumped or if you would like to check your work, then select the View Solution button, which is located directly under each problem.

The combination function is used to solve probability counting problems. Several examples are presented with detailed solutions.

In this activity, students evaluate expressions using permutations and combinations of data elements on the calculator. They solve problems using these counting principles.
