A resource for the classroom - problems involving probabilistic reasoning

This issue of the magazine has an article linked to the recent publication, Key Ideas in Teaching Mathematics. There is a website that accompanies the book which provides links to some relevant resources. Our article this month is related to probabilistic reasoning so the resources for the classroom are a suite of problems that involve reasoning about uncertainty. Some of these problems may be familiar whilst others may be new to you; all have been chosen to develop and deepen understanding.

The website identifies six themes within the key idea of reasoning about uncertainty; intuitions, misconceptions, simulations, modelling, distribution and risk. It states:

Lack of information creates uncertainty. In some circumstances, such as card games or sport, this uncertainty can be compelling for both players and spectators. By reasoning about uncertainty, a player can adopt a strategic approach that will improve his or her success rate in the long term, even if it appears ‘unlucky’ in the short term.

The individual problems are:

What will you do now?

You could:

  • select a problem and try it out with a particular class
  • select a problem and work with a colleague to consider how you can use the problem to develop understanding for a group of pupils
  • include some of these problems in your scheme of work
  • consider how these problems develop the powerful aspects of the curriculum and the links between them.

Do tell us what you find out...
