I taught this game to my students last year to help them practice multiplication and division facts and also develop strategies. The rules of the game are below:
Rules for Factors and Multiples
1. The first player chooses an even number less than 50 and marks it with initials or a marker. Pinto beans are a good size for this game board.
2. The second player chooses a number that is either a factor or a multiple of the first number and places his/her mark on that square.
3. Players continue to take turns covering squares that are a factor or a multiple of the previous square.
4. When a player cannot find a factor or multiple of the last number played, he/she loses the game.
