PROBLEM TO BE SOLVED: To provide a three-dimensional structure creation kit and a three-dimensional structure, capable of developing a space recognition capacity and a three-dimensional shape recognition capacity in a process of assembling, and stimulating, even after the completion of the assembly of the three-dimensional structure, intellectual curiosity in discovering an interesting rolling manner of the three-dimensional structure, predicting the movement thereof, and thinking the reason for the movement.SOLUTION: The three-dimensional structure creation kit for creating a three-dimensional structure by combining components includes: sheet-formed outer surface units each comprising a polygonal surface, folding tabs provided at each of the sides of the polygonal surface, and notches provided in the vicinity of the center of each side; engagement pieces each having two clip parts to be inserted into the notches; an inner unit having slits to be fitted with the engagement pieces, and having a circular aperture that is surrounded by four surfaces having the same areas; and a center ball having a diameter approximately the same as that of the aperture and being formed with an elastic material.SELECTED DRAWING: Figure 13 |
