This is a simple game for teaching probability. I remember one of my own teachers using it, and I’ve recreated the game board for my own use. The rules are quite simple:
- Each student receives 12 tokens, 2 dice and a worksheet.
- The student places the 12 tokens on any of the 12 spaces on the Start side of the river.
- The student rolls the dice. They may move one token across the river in the space that matches the dice roll.
- The object of the game is to move all of the tokens across the river in the least number of rolls.
The students quickly discover that some numbers come up more often than others, and that a pair of dice will never roll 1. For a more advanced lesson, different means of generating numbers could be used: a 12-sided dice, three 4-sided dice, twelve coins, a spinner and so on.
