Abstract

The utility model provides a novel solid geometry demonstration teaching aid which belongs to the field of a teaching aid and comprises brackets, rubber bands and hooks. Twelve brackets with equal width are designed into a cube structure in a lap-joint manner, positioning holes with equal diameter are respectively arranged on the inner end surfaces of the brackets, the hooks are respectively arranged at the two ends of the rubber bands, and the rubber bands are respectively arranged at the inner parts of the brackets forming the cube structure through the arrangement that the hooks are respectively located between two positioning holes. Compared with the prior art, the novel solid geometry demonstration teaching aid is convenient for use and is convenient for students to understand serial knowledge about solid geometry; a teacher can adjust the positions of the rubber bands at any time in the teaching process only by hanging the rubber bands with the hooks in the positioning holes so as to splice a spatial pattern in certain shape, thereby improving learning interests of the students, gradually developing interests of the students in the solid geometry and promoting continuous process of the students in learning interests.

Description

How much demonstration teaching aids of novel solid

1, technical field

The utility model relates to the teaching aid technical field, how much demonstration teaching aids of specifically a kind of novel solid.

2, background technology

Requirement for space imagination in the existing solid geometry teaching is more and more higher, as tripleplane's view, centrum, relevant knowledges such as cylinder, and present form of teaching is by teacher explanation and teacher's graphing on blackboard of courseware to be realized, teacher is in order to allow students grasp spatial entities, have to adopt the method for paper folding or cutting to be given lessons, this form of teaching is for students ' understanding and grasp solid geometry knowledge certain degree of difficulty is arranged, and delay instructional blocks of time, particularly then more difficult for the student who just relates to solid geometry, long-time simple study by planar graph also can make the student produce to be weary of sense, and how to cultivate the solid geometry interest of students, and can allow the student grasp solid geometry knowledge in the time at only course, further improving the efficient of giving lessons is the common purpose that teacher gives lessons.

3, summary of the invention

The utility model is at above-mentioned the deficiencies in the prior art, provides a kind of novel solid several demonstration teaching aids of watching.

How much demonstration teaching aids of novel solid of the present utility model are realized in the following manner, structure comprises support, bungee and hook, wherein 12 wide support overlap joints are arranged to cube structure, the inner face of each support is provided with the pilot hole of same diameter, the bungee two ends respectively are provided with hook, and bungee is by being arranged on hook the inside that is arranged on the cube structure support between two pilot holes.

The inner face of support is provided with two or more pilot holes.

The utility model is compared with prior art, has following outstanding beneficial effect:

(1) the convenient use, be convenient to the serial knowledge that the student understands solid geometry, as long as will having the bungee of hook in the process of giving lessons, teacher is hooked in the pilot hole, can adjust the position of bungee at any time, promptly can be spliced into the space diagram of definite shape, and according to circumstances select for use the bungee of different colours to distinguish space diagram, make the student just can know the relevant knowledge of solid geometry at short notice.

(2) improve learning interest, utilize the mode of teaching aid teaching, can progressively cultivate the interest of students, in interest, constantly improve in study then, got rid of the phenomenon that allows the student be weary of because of uninteresting planimetric map for solid geometry.

Fig. 1 is the perspective view of how much demonstration teaching aids of novel solid;

Fig. 2 is the structural representation of the bungee of how much demonstration teaching aids of novel solid.

Description of reference numerals: 1, support, 2, pilot hole, 3, bungee, 4, hook.

5, embodiment

Explain below with reference to Figure of description how much demonstration teaching aids of novel solid of the present utility model being done.

As shown in Figure 1, how much demonstration teaching aid structures of novel solid comprise support 1, bungee 3 and link up with 4, wherein 12 wide support 1 overlap joints are arranged to cube structure, the inner face of each support 1 is provided with the pilot hole 2 of same diameter, and the inner face of support 1 is provided with two or more pilot holes 2.

As shown in Figure 2, bungee 3 two ends respectively are provided with hook 4, bungee 3 is arranged on the inside that is arranged on cube structure support 1 between two pilot holes 2 by linking up with 4, and the bungee 3 that can use different colours is as teaching aid, so that see the face shaping structure of space diagram more intuitively.

The teacher is in the process of giving lessons, only need the hook 4 of bungee 3 both sides is hooked in the pilot hole 2 of support 1, the figure that can form the different shape structure, in Fig. 1,6 bungees 3 have been formed oblique pyramid, and the student can more clearly learn the shape of pyramid, relation theorem of corner etc. between pyramid, allow the student grasp the centrum relevant knowledge of series more easily, play the effect of drawing inferences about other cases from one instance.

By means of the solid geometry demonstration teaching aid, can finish the demonstration of tripleplane's teaching, be sidelong at demonstration teaching aid one and put a light source, place fine flour plate, the projection relation of the arbitrary graphic of seeing cube structure support 1 inside clearly that can be complete at opposite side.

The use step of how much demonstration teaching aids of novel solid of the present utility model is as follows:

Hang over by hook 4 in the pilot hole 2 of support 1, can build solid geometry figure arbitrarily,, conveniently realize the shape and the structural attitude of many visual observation solid geometry figure by the rotation of the multi-angle of square framework with bungee 3 both sides.

Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.

Claims
