TLF ID L2379
Race two cars along a track. Use a coloured 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 coloured sectors. For example, give a red car the best chance of winning by selecting a favourable 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 colour with the largest sector on the spinner landed on most often? This learning object is one in a series of six objects.
