Villagers begin to count-one at a time no when they get to the forbidden number, a multiple of the forbidden number, or a larger number with the forbidden number in it, they must say “plums.” For example, 1, 2, 3, plums, 5, 6, 7, plums, 9, 10, 11, plums, 13, plums, 14... Add another “forbidden number” when students are familiar with the game and need more of a challenge. Or offer a “reward” Gummibärchen?) if they successfully make it to 100.
