Learning objects Spinners: spin and label

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.



Educational details

Key learning objectives
  • Students differentiate between equal and unequal likelihood.
  • Students explore the relationship between sample space and likelihood of outcomes.
  • Students interpret data in tables and graphs.
  • Students apply 'likelihood language' to compare and describe chance situations.
  • Students use proportional thinking to predict and compare the outcomes of random generators.
Educational value
  • Students compare theoretical outcomes and actual results.
  • Provides area-based random generators to test probability predictions.
  • Experimental results are dynamically displayed as data tables and frequency graphs showing progress in a car race.
  • Includes scenarios with equal or unequal probabilities.
