Classroom Spinners is a collection of spinners specifically designed for educators. Using a slider the spinner can be changed to accommodate a variety of setups: 3, 4, 5, 6, 8 or 10 sections. Sections can be labelled with either numbers or letters. Use Classroom Spinners to conduct probability experiments by spinning the spinner a specific number of times. With your students compare how the experimental probability compares with the theoretical probability?
