  • Patent number: 5688126
    Abstract: An arithmetic game for teaching students basic mathematical skills includes a playing board, four dice, and a complement of playing pieces, or markers. Indicia disposed on the boards and dice determine whether and where a player may place a marker on the board. Board indicia includes numerals two-dimensionally arranged to form a mathematical table. Indicia disposed on the dice includes numerals and mathematical functions. Results are mathematically calculated by a player from the various two numeral combinations presented by the dice. The player evaluates the results to assess the strategic significance of each, and a marker is placed at a position on the mathematical table corresponding to the chosen result. The first player to connect his or her markers from one side of the mathematical table to the other side wins.
