Abstract

The utility model relates to a demonstration tool for geometric teaching. The demonstration tool is characterized by comprising straight rods (1) and a protractor (2), wherein the connection relationship is as follows: the nine straight rods (1) are movably connected end to end, and the protractor (2) is arranged on any one connection point. The straight rods (1) are fixedly connected via screws and capable of being disassembled and assembled as needed. The demonstration tool for geometric teaching disclosed by the utility model is detachable, foldable and convenient to carry; the plurality of straight rods form a specific plane geometric figure after being fastened together via the screws, so that various plane geometric figures can be intuitively demonstrated for students; and the arranged protractor can be used for measuring the angles of the geometric figures when necessary, so that the understanding of the students for the angles of the figures is impressed.

Description

The several teaching demonstration equipment
Technical field
The utility model belongs to the teaching aid technical field, particularly a kind of several teaching demonstration equipment.
Background technology
When the knowledge of how much classes of study, more hard to imagine and the various geometric differences of understanding of a lot of students are with related, the teacher is when teaching, and is main still by ruler and chalk, and geometric figure is drawn on the blackboard to student explain, the means of giving lessons like this waste time and energy, more stiff, vivid not, if the teacher can carry out by the teaching aid of demonstration the geometric figure teaching, can be beneficial to student's fast understanding and grasp geometric figure knowledge, improve learning efficiency.
The utility model content
The purpose of this utility model is to provide a kind of several teaching demonstration equipment, can make teacher's teaching convenient, and teaching process is more lively, and Students ' Learning is lighter.
For reaching described purpose, the utility model discloses a kind of several teaching demonstration equipment, it is characterized in that comprising straight-bar (1) and protractor (2); Its annexation is: described 9 straight-bars (1) head and the tail are movably connected, and protractor (2) is set on arbitrary tie point therein.
Described straight-bar is fixedly connected with by screw between (1), can carry out as required dismounting.
By said structure, the following technique effect of realization of the present utility model:
(1) detachable, folding, easy to carry;
(2) with some straight-bars by screw fastening together after, form specific plane geometric shape, can demonstrate various plane geometric figures to the student intuitively.
(3) protractor that arranges where necessary can the measure geometry figure angle, make the student more deep to the understanding of angle.
Detailed content of the present utility model can obtain by explanation described later and institute's accompanying drawing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1-straight-bar, 2-protractor.
The specific embodiment
Below in conjunction with drawings and Examples the specific embodiment of the present utility model is further described, following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, the specific embodiment of the present utility model is: comprise straight-bar 1 and protractor 2; Its annexation is: described 9 straight-bars, 1 head and the tail are movably connected, and on arbitrary tie point protractor 2 are set therein.
Be fixedly connected with by screw between the described straight-bar 1, can carry out as required dismounting.
It is evident that above description and record only are for example rather than in order to limit disclosure of the present utility model, application or use.Although described in an embodiment and be described in the drawings embodiment, but the optimal mode that the utility model does not limit by the accompanying drawing example and the conduct of describing is in an embodiment thought at present to be implementing the specific examples of instruction of the present utility model, and scope of the present utility model will comprise any embodiment of the specification that falls into the front and appended claim.
