Description

Geometry Teaching Demonstration Tools

technical field

The utility model belongs to the technical field of teaching appliances, in particular to a geometry teaching demonstration appliance.

Background technique

When learning geometry, it is difficult for many students to imagine and understand the differences and relationships of various geometric figures. When teaching, teachers mainly use rulers and chalk to draw geometric figures on the blackboard to explain to students. Such teaching The method is time-consuming, laborious, rigid, and not vivid enough. If teachers can use demonstration teaching tools to teach geometric figures, it will help students quickly understand and master the knowledge of geometric figures and improve learning efficiency.

Utility model content

The purpose of the utility model is to provide a geometry teaching demonstration tool, which can make the teacher's teaching more convenient, the teaching process more vivid, and the students' learning easier.

In order to achieve the above purpose, the utility model discloses a geometry teaching demonstration tool, which is characterized in that it includes a straight rod (1) and a protractor (2); the connection relationship is: the nine straight rods (1) are connected head to tail , set the protractor (2) on any of the connection points.

The straight rods (1) are fixedly connected by screws and can be disassembled as required.

Through the above structure, the utility model realizes the following technical effects:

(1) Detachable, foldable, easy to carry;

(2) Several straight rods are fastened together by screws to form a specific plane geometric shape, which can intuitively demonstrate various plane geometric figures to students.

(3) The set protractor can measure the angle of geometric figures when necessary, so that students can have a deeper understanding of angles.

The details of the present invention can be obtained from the following description and the accompanying drawings.

Description of drawings

Fig. 1 is the structural representation of the utility model.

In the figure, 1-straight rod, 2-protractor.

Detailed ways

The specific implementation of the utility model will be further described below in conjunction with the accompanying drawings and examples. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

As shown in Fig. 1, the specific embodiment of the utility model is: comprising straight rods 1 and protractors 2; the connection relationship is: the nine straight rods 1 are movably connected end to end, and a protractor 2 is set on any connection point.

The straight rods 1 are fixedly connected by screws, and can be disassembled as required.

Obviously, the above descriptions and records are only examples and not intended to limit the disclosure, application or use of the present utility model. Although the embodiment has been described in the embodiment and described in the accompanying drawings, the utility model is not limited by the examples of the accompanying drawings and described in the embodiment as the best mode currently considered to implement the teaching of the utility model Certain examples, the scope of the present invention shall include any embodiment falling within the foregoing description and appended claims.

Claims (2)
