SOLUTION: A plurality of pieces 2, on which a figure is shown and so formed as to fit a part 4 into which a figure in a problem section of a plurality of calculation formulae provided on a board 1 is put, are used to complete the problem section of the calculation formulae on the board 1. Then, the problems are solved, and a plurality of pieces 3 on which a figure is shown and so formed as to fit a part 5 into which the figure of an answer is put are used to complete the answers. After checking the correct answers, the pieces 2 and 3 fitted on the board 1 are all removed to be in a random order.
