A fun probability game for KS3 that is easy to access, and helpful introduction to sample space and expressing probabilities as a fraction.
How to play:
you'll need a racing track sheet which is on slide 5 of the powerpoint.
Each person picks a horse number and writes their initials next to that horse.
Take it in turns to roll two 6 sided dice. Add together the numbers shown and put one cross in that horses row. The first one to reach the finish line wins!
As a challenge I have made a racing sheet (the word document) that can be used with two dodecahedral dice.
