Lesson: Counting With Repetition Where Order Does Not Matter Mathematics

Start Practising

In this lesson, we will learn how to use combinations to count with repetition where order does not matter.

Lesson Plan

Students will be able to

  • solve problems in which we need to count with repetition and in which we treat different orderings of the same collection as equivalent (e.g., {𝑎,𝑏,𝑐}={𝑐,𝑏,𝑎}),
  • use double counting techniques to think about problems in combinatorics and mathematics more generally.
