there are spinners available with most interactive whiteboards
for those that don't have these available - and with some benefits from other functionality - here are 3 examples of programmes:
experimenter (NRich 6033)
students could use a pencil and a paper clip to simulate using a spinner
using ICT you can have spinners with various sets of numbers and then add or subtract these
runs are single, in hundreds or 50 000s
one interest might be to compare e.g. experimental outcomes for subtracting numbers on two spinners, one with 5 numbers and the other with 4 and then theoretical probabilities (via a two-way 'outcomes' table)
spinning spinners (Actis)
has a restricted set of options and no speedy trialler
but the visuals are good and it can be left in the background, building up a bar chart
there is one difficult to caculate option (the bottom one) which is interesting...
Interactivate (Shodor) has two spinner programmes available:
adjustable spinner
this automatically compares an experimental with a theoretical outcome
and experimental probability
which enables dice to be created with different numbers on their faces (only the same on both) as well as different spinners
