**Instructions for Use**

**Adjustable Spinner** allows students to create spinners with different numbers and sizes of sections, to meet specific probability criteria.

Make up some probability rules for a spinner. Include the number of coloured sections and the probability of each colour. Now use the interactive activity to create a spinner that matches your rules. Try creating three spinners, one with 3 sections, one with 4 sections, and one with 5 sections.
