Race two cars along a track. Use a colored spinner (a dial with a pointer) to determine which car moves along the track. Try to achieve a given race result by choosing a spinner with a suitable combination of colored sectors. For example, give a red car the best chance of winning by selecting a favorable spinner. Test the spinner over a number of spins. Compare the actual results with the expected results. Does a fair spinner result in all cars winning equally often? Is the color with the largest sector on the spinner landed on most often? This learning object is one in a series of six objects.
1. Students differentiate between equal and unequal likelihood.
2. Students explore the relationship between sample space and likelihood of outcomes.
3. Students interpret data in tables and graphs.
4. Students apply 'likelihood language' to compare and describe chance situations.
5. Students use proportional thinking to predict and compare the outcomes of random generators.
