Abstract
The present invention provides a figure plate set (10) for learning that comprises a plate member (4) having a concave portion (5); and groups of figure plates (1, 2, 3) that can form a regular polygon by being combined together, wherein the group of figure plates (1, 2, 3) can be stored on concave portion (5) in a state that the regular polygon is formed and the regular polygon is inscribed in an inner peripheral wall (6) of the concave portion (5). From the above, the user can experientially understand the regular polygon through the work of combining the figure plates. Thus, ability of geometric thinking about regular polygon is increased. In addition, since the plate member (4) has the concave portion (5), the group of figure plates (1, 2, 3) can be positioned. Thus, the figure plates (1, 2, 3) can be combined easily.
