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.

Provided is a design board set (10) for educational use, equipped with a plate member (4) in which a recess (5) is formed, and sets of design boards (1, 2, 3) which can be assembled together to form regular polygonal shapes. When assembled to form regular polygonal shapes, the sets of design boards (1, 2, 3) can be accommodated in internal contact against the inside peripheral wall (6) of the recess (5). In so doing, experiential understanding of regular polygonal shapes is deepened through the process of assembling the design boards into regular polygonal shapes, which is helpful in improving geometric observational abilities in relation to regular polygonal shapes. Moreover, because the plate member (4) is provided with the recess (5), the sets of design boards (1, 2, 3) can be positioned, making the assembly process easy.

Provided is a figure plate set (10) for learning, the set including: a first triangle plate (1) that is in a shape of an isosceles triangle having an apex angle of 108° and base angles of 36° each; and a second triangle plate (2) in a shape of an isosceles triangle having an apex angle of 36° and base angles of 72° each. The length of the equilateral sides (7, 8) of the first triangle plate (1), and the length of the equilateral sides (14, 15) or the base side (16) of the second triangle plate (2) are equal to each other, so that the first triangle plate (1) and the second triangle plate (2) can be combined to form a new triangle.
