What: We are learning to predict possible outcomes in an experiment.

Why: This will help us to improve our ability to make predictions.

How: I’ll be able to conduct a chance experiment using a spinner.

In pairs, you will collaborate and negotiate to design and build your own spinner online, choosing how many parts you want your spinner divided into and the colours of each part.

  1. Predict what the outcomes would be if the spinner were to spin 10 times.
  2. Spin the spinner 10 times and record the results.
  3. Describe why the results may be the same or different to their predications.
  4. Share your ideas and discuss your strategies – recording them in their maths notebooks and post as a comment below.
