Description
Test your understanding of chance by constructing coloured spinners (dials with pointers) according to given criteria. Choose up to twelve equal-sized parts. Choose up to three colours for the parts of each spinner. There are 16 different tasks. For example, make a red and blue spinner with seven parts so that the chance of spinning red is less than spinning blue. Or, choose the number of parts and make a spinner that is likely to spin 20% red, 40% blue and 40% yellow
Objective

Students interpret the language of chance (equally likely, more/less likely, impossible, certain, relative percentage) and apply these in order to construct spinners.
Students demonstrate the relationship between a sample space (spinner) and the likelihood of particular outcomes by constructing spinners according to given criteria.
Students create mathematically equivalent spinners given specific criteria for their construction.
