Abstract

Abstract A game for children for aiding them in learning their arithmetic tables, particularly multiplication, the game includes a game board with a centrally located transparent hemispheric shell mounted on a flexible leaf spring, a plurality of dice which are contained within the hemisphere then become changed in position by depressing and releasing the hemispheric shell and a peg board with associated pegs for scoring correct answers to the changed dice by one or the other of two players. The game board includes a receptacle for storage of the pegs, the receptacle having a slide cover on which the arithmetic tables are set forth for verifying the answer of the player whose turn it is to provide the correct answer to the arithmetic operation displayed.
