Abstract
A geometrical demonstrator is inserted in the holes corresponding to the edge strips and fixed by bolts, which can demonstrate the relation between polygonal figures and between corners visually and dynamically, has simple structure, multiple purposes and convenient use, and can enhance the learning interest of students, thereby improving the teaching quality.
Description
Affiliated technical field
The utility model relates to the geometric configuration demonstration device of energy transformation geometry shape in the teaching aid field.
Background technology
The teacher is in the several teaching process, to geometric teaching, generally be with corresponding diagram plots on blackboard, explain then, when sum up concluding concerning between the various figures, it often also is their figure that draws one by one, by analyzing, contrast, conclude, summary is to student explain, in the modern advanced teaching method, also can be by means of multimedia teaching facility, this has strengthened the dynamic directly perceived of teaching to a certain extent, but above teaching has the following disadvantages: 1, only diagram plots on blackboard, lack intuitive and stereoscopic sensation, be unfavorable for improving students'interest in learning; 2, the corner of various figures relation can not be intuitively, dynamically show; 3, utilize multimedia teaching facility, CAI software design trouble, and also present most of school does not have multimedia teaching facility.
Summary of the invention
Be convenient teaching, the utility model provides a kind of geometric configuration demonstration device that can intuitively, dynamically express between the geometric figure and concern between the corner.
The utility model comprises edge strip and bolt, circular hole is arranged on the relevant position on the edge strip, on making, utilize tetragonal instability, with the fixing edge strip of stove bolt, by being out of shape or moving the accessory of self, various special geometric figures can be formed, and the relation between the geometric figure, between the corner can be demonstrated intuitively.
The utility model is compared with general teaching method, and the many usefulness of a tool are easy to use, and directly perceived, dynamic demonstration can strengthen student's interest, thereby improves the quality of teaching.
Description of drawings
Accompanying drawing is the utility model structure diagram.
Specific embodiments
The utility model comprises edge strip 1 and bolt 2, edge strip 1 usefulness thickness is that stainless steel steel bar or the batten of 1mm made, relevant position has aperture on it, the position of aperture should be beneficial to realize the conversion between various quadrilaterals and the triangle and demonstrate out between the figure intuitively, relation and tetragonal character between limit and the limit, between limit and the angle, between angle and the angle, bolt 2 inserts fixedly each limit of conversion of respective aperture, and standby limit 3 is used for the auxiliary pattern conversion.
Claims (1)
- A kind of geometric configuration demonstration device comprises edge strip (1) and bolt (2), it is characterized in that having aperture on the edge strip (1).
