Abstract
The utility model discloses a solid geometry teaching aid, which comprises two triangular pyramid bodies and two rectangular pyramid bodies, wherein two side surfaces of the triangular pyramid bodies are vertical to the bottom surface, two side surfaces of the rectangular pyramid bodies are vertical to the bottom surface, in addition, the side surfaces of the triangular pyramid bodies vertical to the bottom surface and the side surfaces of the rectangular pyramid bodies vertical to the bottom surface have the same edge length, and magnetic strips are arranged on the edges of the triangular pyramid bodies and the rectangular pyramid bodies. The solid geometry teaching aid has the beneficial effects that the structure of the solid geometry teaching aid is simple, one set or more than one set is used, various different geometry bodies can be split through various different split joint combinations, in addition, the edges of the geometry bodies have the magnetism, the split connection can be carried out according to the requirements, the solid geometry teaching aid can be repeatedly used, the intuition is strong, the teaching by teachers is convenient, and the solid geometry teaching aid is favorable for the understanding by students.
Description
Technical field
The utility model relates to a kind of solid geometry teaching aid, belongs to the middle school mathematics solid geometry teaching aid.
Background technology
At present, teaching aid is for teacher's object teaching, and the student understands the considerable effect of playing.The solid geometry teaching aid of selling on the market, contained single quantity is more in the cover, serves as between one or two monomer and often can not be spliced into another simple geometric body, and the monomer frequency of utilization is not high, and on the high side, and the student is difficult to bear.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of monomer number less, the solid geometry teaching aid that frequency of utilization is higher.
The utility model is realized by following measure:
Solid geometry teaching aid of the present utility model, comprise two triangular cones and two rectangular pyramid bodies, two lateral vertical of described triangular cone are in the bottom surface, two lateral vertical of rectangular pyramid body are in the bottom surface, and the triangular cone equates that with the side length of side of rectangular pyramid body perpendicular to the bottom surface edge of described triangular cone and rectangular pyramid body is provided with magnetic stripe perpendicular to the side of bottom surface.
The beneficial effects of the utility model are:
The utility model is simple in structure, use a cover or more than the cover, splice and combine by various, just can risk various solid, and the solid edge has magnetic, can carry out assembly unit as required and connect, and can use repeatedly, intuitive is strong, be convenient to teachers ' teaching, more help the student and understand.
Description of drawings
Fig. 1 is the structural representation of the utility model triangular cone.
Fig. 2 is the structural representation of the utility model rectangular pyramid body
Among the figure: 1 triangular cone, 2 rectangular pyramid bodies, 3 magnetic stripes.
Embodiment
Now be described further with accompanying drawing in conjunction with the embodiments:
As shown in Figure 1, 2, solid geometry teaching aid of the present utility model, comprise two triangular cones 1 and two rectangular pyramid bodies 2, two lateral vertical of described triangular cone 1 are in the bottom surface, two lateral vertical of rectangular pyramid body 2 are in the bottom surface, and triangular cone 1 equates that with the side length of side of rectangular pyramid body 2 perpendicular to the bottom surface edge of described triangular cone 1 and rectangular pyramid body 2 is provided with magnetic stripe 3 perpendicular to the side of bottom surface.
More than use one cover or overlaps, splice and combine, just can risk various solid by various, and the solid edge has magnetic, can carry out assembly unit as required and connect, and can use repeatedly, intuitive is strong, is convenient to teachers ' teaching, more helps the student and understands.
