Abstract
The utility model provides a mathematical figure demonstration teaching aid. A square body serves as a base body; the sides of the square body are telescopic sides; the two ends of each side can be rotatably hinged to ends of two adjacent sides; each telescopic side comprises a fixed section and two extension sections which can slide along the fixed section and have the same length as the fixed section; the middle portions of the plate faces of the fixed sections and the extension sections are provided with grooves in the length direction; each fixed section is provided with a shaft which can be inserted in the grooves of the corresponding extension sections and can slide freely; and each extension section is provided with a shaft which can be inserted in the groove of the corresponding fixed section and can slide freely. Compared with the prior art, the mathematical figure demonstration teaching aid is simple in structure and convenient to operate, can be used for dynamic demonstration, enables students to deeply understand and master knowledge, and can improve the teaching effect.
Description
Technical field
The utility model relates to teaching aid technical field, is specifically related to a kind of mathematic graph demonstration teaching aid.
Background technology
In mathematics studying, plane geometry has occupied very consequence.But in current teaching process, figure demonstrating just uses static images mostly, student can only produce perceptual knowledge to figure itself, is difficult to it to carry out more deep understanding.Therefore, need a kind of mathematics teaching aid that can carry out dynamic demonstration, make student can coordinate the better study that must complete geometric knowledge of teacher.
Summary of the invention
The purpose of this utility model is the problem that overcomes teaching aid deficiency in mathematical education, provides a kind of simple in structure, can realize dynamic demonstration, makes student can understand the mathematic graph demonstration teaching aid of distinguishing and contacting between figure.
This mathematic graph demonstration teaching aid, take square as matrix, described foursquare limit 1 is scalable limit, and the two ends on every limit respectively can rotating hinge be connected on the end on adjacent both sides.
Described limit comprises canned paragraph 11 and two extensions 12 isometric with canned paragraph that can slide along described canned paragraph.
In the middle of the plate face of described canned paragraph 11 and extension 12, be equipped with along its length groove 2, canned paragraph is provided with and can inserts in the groove of extension and the axle 3 being free to slide, and extension is also provided with in the groove that can insert canned paragraph and the axle being free to slide.
The utility model compared with prior art, has the following advantages: simple in structure, easy to operate, can carry out dynamic demonstration, and be convenient to student and deeply understand and grasp knowledge, teaching efficiency is obviously improved.
Accompanying drawing explanation
Fig. 1 is the utility model basic status structural representation.
Fig. 2 is the utility model part extended state structural representation.
Wherein, 1 is limit, and 11 is canned paragraph, and 12 is extension, and 2 is groove, and 3 is axle.
Embodiment
Referring to accompanying drawing 1 and accompanying drawing 2.
This mathematic graph demonstration teaching aid, in the time of basic status, is a square, and four edges 1 is scalable limit, and the two ends on every limit respectively can rotating hinge be connected on the end on adjacent both sides.
Scalable limit comprises canned paragraph 11 and two extensions 12 isometric with canned paragraph that can slide along described canned paragraph.
In the middle of the plate face of canned paragraph 11 and extension 12, be equipped with along its length groove 2, canned paragraph is provided with and can inserts in the groove of extension and the axle 3 being free to slide, and extension is also provided with in the groove that can insert canned paragraph and the axle 3 being free to slide.
