Go round and round to compare theoretical and experimental probabilities. Learners set the number of sectors and the number of spins for a spinner. Then, a table displays the experimental and theoretical probabilities of the spinner for scholars to analyze. To put their thinking skills to to the test, pupils compare the size of the sectors using a graphical display of the experimental results.

Instructional Ideas

• Lead a discussion on whether it is expected that the experimental and theoretical probabilities would be the same
• Use the spinner to create simulations based on equal theoretical probabilities

Classroom Considerations

• Assumes an understanding of probability, both experimental and theoretical
• The worksheet's focus is on the geometrical aspect of the size of the central angles

• This resource is only available on an unencrypted HTTP website.It should be fine for general use, but don’t use it to share any personally identifiable information

Pros

• Provides directions on how to adjust and operate the applet
• Contains links to discussion on probability concepts associated with spinners

Cons

• None
