Description
Learn how to count possibilities without missing any — or counting the same one twice.
In Lesson 1 of Counting & Combinatorics, learners explore systematic ways of organising possibilities using lists, tables and tree diagrams.
Along the way they investigate outfits, codes, handshakes and triangles, and begin thinking about an important question in combinatorics: does order matter?
Included
- Lesson Handout — guided examples, practice, learning prompts and a challenge.
- Exercises — extra questions for practice, extension and revision.
- Answers and discussion at the back of both resources.
The materials are designed for a parent and child to explore together or for an older learner to work through independently.
Topics include:
- systematic lists;
- tables;
- tree diagrams;
- counting codes;
- avoiding double counting;
- deciding whether order matters.
This is a printable companion to Lesson 1: How many possibilities? in the free Sumthing Else Counting & Combinatorics course.
