<p>PROBLEM TO BE SOLVED: To provide a figure board set capable of experimentally deepening a geometrical observation much more through the work and which is good in handleability.SOLUTION: A figure board set 10 for learning includes: a plate member 4 in which a recess part 5 is formed; and sets 1 to 3 of the figure board capable of forming a regular polygon by the combination of the sets. The sets 1 to 3 of the figure board can be stored by internally contacting the inner peripheral wall surface 6 of the recess part 5 in a state of forming the regular polygon. As a result, the experimental understanding of the regular polygon is deepened through the work of forming the regular polygon by combining the figure boards and contributes to the improvement of the geometrical observation power relating to the regular polygon. Further, since the figure board includes the recess part 5 of the plate member 4, the sets 1 to 3 of the figure board can be positioned so that the assembly work is facilitated.</p> |
