  • Patent number: 6089871
    Abstract: A method and apparatus for teaching mathematical skills to players of all ages includes a game board having 100 spaces printed on a first board side, the spaces numbered from one to ninety-nine and having one logo space. Each space, in addition, has printed on it a prime number factorization, an exponential representation, or both, corresponding to the number contained within the particular space. Each player rolls a plurality of dice having prime numbers assigned to each die face. The object of the game is for players to score points by occupying board spaces between spaces imprinted with prime numbers. A space is occupied by applying the rolled dice to match a prime number factorization of a particular space, whereupon a chip is placed on the particular space to denote ownership. The dice used to occupy a space are then no longer used for occupying other spaces during a round of play.
