ABSTRACT:
A mathematics game board apparatus including an indicia board having a plurality of indicia spaces including numbers and mathematical function indicia for rotary movement upon a base board, a matching board having a plurality of circular matching openings therethrough and adapted to be rotated independently of and above the indicia board, and a transparent sheet member having a playing surface fixed to the base board above the matching board for supporting at least one playing piece, the position of the playing piece and the rotary positions of the matching board and the indicia board indicating a number upon which a mathematical function is to be performed.
The game board apparatus further includes a rotary registry board mounted concentrically between the matching board and the transparent sheet member and having registry openings identical in number and location to the matching openings, for alternatively concealing and exposing the indicia spaces through corresponding matching openings.
The indicia spaces may be color-coded numbers.
