Mystery spinner: challenge

Mystery spinner: challenge

TLF ID L2384

Look at results in a frequency graph compiled after testing an unseen spinner. Work out the likely proportions of colours in the mystery spinner. Use a tool to build a new spinner (a dial with a pointer). Choose up to five equal-sized sectors. Fill the sectors with up to five colours. For example, make a five-part spinner with two red sectors, two blue sectors and one yellow sector. Test the new spinner over a number of spins. Look at a graph of the test results. Compare it to the graph generated by the mystery spinner. Are the results similar?

Educational details

Educational value
  • Students use frequency graphs and data tables to compare theoretical outcomes and actual results.
  • Includes a tool enabling students to construct area-based random generators in the form of spinners and to run trials to generate short-run, medium-run and long-run data.
  • The spinner tool maximises student choice, control and creativity as they explore the results from making various spinners.
  • Experimental results are dynamically displayed in a column graph and a table that shows both theoretical outcomes and actual results.
  • Supports both visual and numerical strategies through use of random generators, graphs and tables.
