# Spinners: basic builder

TLF ID L2376

Use a tool to build coloured spinners (dials with pointers). Choose up to six equal-sized sectors. Choose up to four colours for the parts of each spinner. For example, make a three-part spinner with two blue sectors and one yellow sector. Test each spinner over a number of spins. See which colour the pointer lands on each time. Watch the graph build and the numbers change in the results table after each spin. Compare the actual results with the expected results. This learning object is one in a series of six objects.

#### Educational details

Key learning objectives
• Students explore the difference between the information provided by short-run, medium-run and long-run data.
• Students explore the relationship between sample space and likelihood of outcomes.
Educational value
• Students compare theoretical outcomes and actual results.
• Includes a tool enabling the user to construct area-based random generators in the form of spinners and to run trials to generate both short-run (10 spins) and long-run (10 000) 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.
