Test a colored spinner (dial with pointer) with three equal-sized sectors. Use a tool to build more spinners. Choose up to twelve equal-sized sectors. Choose one of three colors for each part of a spinner. For example, make a three-color spinner with six red sectors, four yellow sectors and two orange sectors. Test the spinner over a number of spins. See which color the pointer lands on each time. Watch the graph build after each spin. Compare the actual results with the expected results. Check whether increasing the proportion of a color on a spinner increases the chances of the spinner landing on that color. This learning object is one in a series of six objects.

4. Students use proportional thinking to predict and compare the outcomes of random generators.
