Abstract

The utility model discloses a geometric body diagonal or altitude visualization teaching model, characterized by comprising a hollow transparent or semitransparent geometric body in which a visual diagonal or altitude is arranged. Because the surfaces of the geometric body are all transparent or semitransparent, the diagonal or altitude is displayed with a vivid color fine line, not affecting the appearance of the whole geometric body, and not shielding the side surfaces. The diagonal or altitude penetrates the interior of the geometric body in the fine line manner, and is carried out fixed knotting or movable stretching outside vertexes, thereby achieving the purpose of directly observing the geometric body diagonal or altitude via the transparent or semitransparent surfaces of the geometric body.

Description

A kind of solid diagonal line or the visual teaching mode of high line
Technical field
The utility model relates to a kind of teaching mode, and concrete relating to is a kind of with solid diagonal line/visual teaching mode of high line.
Background technology
Teaching mode is the auxiliary implement a kind of commonly used in the mathematical education, be used to help the teacher vivider, lecture mathematical knowledge intuitively, effectively, help the student to understand better and grasp mathematical knowledge.For a long time; Teaching such as the interior diagonal line of solid, high line are difficult problems always; Main cause is still not have at present a kind of teaching mode can let observation of students arrive the inner diagonal line of solid, the concrete example of high line; More can't align and measure to form distance conception accurately, existing geometric mould also can't adopt the mode of cutting open to realize this function.
The teaching mode of the utility model has then overcome the problems referred to above.
Summary of the invention
The purpose of the utility model provides a kind of teaching mode, can make the diagonal line of solid or high line visual, and makes high line, diagonal line to measure.Through this model, can let the student observe solid inner diagonal line or high line intuitively, visually, improve students'interest in learning and results of learning greatly, help foster students' and novelty thinking ability.
For realizing the foregoing invention purpose, the utility model is realized through following technical scheme:
A kind of solid diagonal line or the visual teaching mode of high line comprise a hollow transparent or semitransparent solid, and solid inside is provided with visual diagonal line or high line.
The teaching mode of the utility model does not limit the type of concrete solid, common any solid all can, include but not limited to cube, rectangular parallelepiped, hexahedron, octahedron, prism, pyramid, cylinder, circular cone.
Make solid present transparent or semitransparent method and be not restricted, for example organic glass, transparent plastic etc. are prepared into transparent or translucent solid and get final product through transparent material.
In order to make inner diagonal line or high line visual, and be easy to observe, diagonal line that said solid is inner or high line are showed by the fine rule of the color clear of passing solid.
Through said structure, said diagonal line or high line are apparent, and do not have influence on the profile of whole solid, can observe at each face of solid.
After diagonal line, high line etc. passes solid, can be fixed through several different methods, preferably the two ends of lines are separately fixed at the place, summit of solid.That is:
Said diagonal line passes solid inside, fixes perhaps being adhesively fixed in the knotting of outside, summit.
Said high line passes solid inside, and is fixing or bonding except that knotting on summit and bottom center.
According to actual needs, for the ease of using, diagonal line, high line all can stretch.
The diagonal line of the solid of the utility model or the visual teaching mode of high line, its physical geometry not only can be realized traditional function of observation of students geometry shape that lets, and can let the student see through the surface to see that solid is inner, and examine.Through diagonal line, high line are taken out, can reach the purpose that promotes results of learning through the comparison of observation and actual measured results.So not only improve students'interest in learning, foster students', the novelty thinking ability that also helps to cultivate the student.
Description of drawings
Fig. 1 is diagonal line or the structural representation of the visual teaching mode of high line of the solid of the utility model;
Fig. 2 a is the diagonal line or the visual teaching mode horizontal sectional drawing of high line of the solid of the utility model;
Fig. 2 b is the diagonal line or the visual teaching mode vertical cross section of high line of the solid of the utility model;
Fig. 2 c is the diagonal line or the visual teaching mode vertical cross section of high line of the solid of the utility model.
Embodiment
The utility model is further specified below in conjunction with accompanying drawing and practical implementation, but not as the qualification to the utility model.
As shown in Figure 1, the utility model comprises a hollow transparent regular octahedron, and this solid is transparent or translucent, visual three diagonal line (11,12,13) that regular octahedron is inner.Diagonal line passes the inner formation of solid with fine rule; Diagonal line outside 6 summits of regular octahedron, tie a knot (21,22,23,24,25,26) fixing.
Shown in Fig. 2 a, 2b, 2c, for the sectional view of the regular octahedron of Fig. 1, analyse and observe from two vertical direction, a horizontal direction respectively, can observe cornerwise distribution situation.
Because regular octahedron is transparent, the student can see through the inner diagonal shape of surface geometry body of solid.
The above embodiment is the utility model preferred embodiment; The utility model is not limited to the foregoing description; Under the enlightenment of the utility model; Those skilled in the art need not spend creative work and the equivalence made replacement, and for example the color of the type of solid, lines etc. is all expected easily, all belongs to the protection domain of the utility model.
