Metallic hexahedron demonstrating Rubik's cube

Abstract

The invention belongs to the technical field of teaching aids for mathematics, and in particular relates to a metal hexahedron display Rubik's Cube, which comprises six square flat plates with the same structure and size assembled into a regular hexagon, and the front and right end faces of the square flat plates are provided with bumps at the central positions. Both ends of the bump are provided with a first hemispherical cavity, the outer surface of the bump is provided with a communication groove at the corresponding position of the first hemispherical cavity, the outer surface of the bump is provided with a passage groove at the inner end surface of the communication groove, and the projection is at the corresponding position of the passage groove A card slot is provided, a rubber ball is provided in the first hemispherical cavity, a rubber strip is provided in the rubber ball in the communication groove, a stopper is provided on both sides of the convex block on the rear end surface and the left end surface of the square plate, and the inner surface of the stopper is on the The corresponding position of the rubber ball is provided with a second hemispherical cavity. Its purpose is to solve the operation trouble caused by the existing hexahedron unfolding and restoration demonstration method, the demonstration is not intuitive enough, and the cut box can only be used as a one-time use item, which is not conducive to the establishment of students' environmental awareness.

Description

technical field [0001] The invention belongs to the technical field of mathematics teaching appliances, in particular to a metal hexahedron display Rubik's cube. Background technique [0002] In mathematics teaching, in order to exercise students' three-dimensional imagination, teachers often use the method of unfolding and restoring the regular hexahedron, so that students can further understand the relationship between three-dimensional figures and plane figures, understand that polyhedrons can be surrounded by plane figures, and let students experience and experience The transformation process of graphics develops students' spatial concepts; [0003] In actual teaching, the teacher uses a regular hexahedron (such as a chalk box) to roughly demonstrate the shape of the hexahedron unfolded and restored, or uses multiple boxes, cuts along different edges, and then unfolds. [0004] However, such a demonstration method is cumbersome to operate, and the demonstration is not i...
