Great Expectations

Great Expectations


This feature offers a new approach to teaching probability.
The articles Probability through Problems outline the thinking behind the approach, and the resources can form the basis of an entire secondary school probability curriculum.
To learn more about the project, see Great Expectations: Probability Through Problems.

Probability Through Problems 
Age 11 to 16
Challenge Level Yellow star

This collection of articles for teachers outlines an approach for teaching probability at secondary level.

Which Team Will Win? 
Age 11 to 14
Challenge Level Yellow star

A practical experiment which will introduce students to tree diagrams, and help them to understand that outcomes may not be equally likely.

The Dog Ate My Homework! 
Age 11 to 16
Challenge Level Yellow star

A practical experiment which uses tree diagrams to help students understand the nature of questions in conditional probability.

Who Is Cheating? 
Age 14 to 16
Challenge Level Yellow star

A practical experiment provides data. Moving onto expected results provides a context to establish the multiplication rule in probability, and an intuitive approach to conditional probability.

Prize Giving 
Age 14 to 16
Challenge Level Yellow star

What's the fairest way to choose 2 from 8 potential prize winners? How likely are you to be chosen?
