  • Patent number: 7059861
    Abstract: The present invention relates to a math manipulative educational learning game in which a plurality of rods are provided for use in various manipulative games designed to teach rudimentary arithmetic skills. In the preferred embodiment, the rods are of various lengths and/or volumes, with the shortest length comprising a unit length, and other rods being formed in integral multiples of the unit length. Various games are disclosed in which a child is encouraged to manipulate the rods in various ways and in order to learn various arithmetic lessons. For example, in one game a Game Master selects any of the rods except the rod having unit length and places it upon a game playing surface. Thereafter, the Partner must select a plurality of rods whose combined lengths equal the length of the rod played by the Game Master. These rods are laid end-to-end along side the rod played by the Game Master in order to demonstrate their length equality.
