Description

Technical Field

[0001] The utility model relates to the technical field of teaching demonstrations, in particular to a demonstration device for mathematics teaching. Background Art

[0002] With the continuous improvement of the education level and the continuous improvement of teaching methods, the demand for teaching tools in modern teaching is increasing day by day. Especially in mathematics teaching, the application of demonstration tools plays a crucial role in helping students understand and master abstract mathematical concepts. Traditional mathematics teaching demonstration tools, such as triangular rulers, protractors, and straight rulers, although they can assist teaching to a certain extent, these tools are often too single, and lack flexibility and interactivity during operation, and cannot fully meet the needs of modern mathematics teaching.

[0003] Especially when explaining geometric figures, such as triangles, quadrilaterals, etc., there are some deficiencies in the traditional tools during the demonstration process. First of all, these tools cannot dynamically adjust the shape and size, which limits the teaching demonstration effect of teachers in the classroom. Secondly, traditional tools need to be manually adjusted by teachers during the demonstration, with cumbersome operations and easy to make mistakes, which affects the fluency of classroom teaching and the attention of students. In addition, most of the existing mathematics teaching tools lack intuitive visual effects and interactivity, and it is difficult to stimulate students' learning interest and participation.

[0004] In order to solve the above problems, it is particularly important to provide a demonstration device for mathematics teaching that can flexibly adjust the shape and size. An ideal demonstration device for mathematics teaching should have the following characteristics: it can intuitively and clearly display the change process of geometric figures; it is easy to operate and can save teachers' teaching time; it has a certain degree of interactivity and can stimulate students' learning interest and participation; at the same time, the device should also have a certain structural stability to ensure that there will be no loosening or deformation during the demonstration process.

[0029] Refer to the attached instruction manual Figures 1-7 , which shows the structural schematic diagram of a demonstration device for mathematics teaching provided by an embodiment of the present utility model.

[0030] The embodiments of the present utility model provide a demonstration device for mathematics teaching, including:

[0031] A number of angle devices, the angle device includes a front cover plate 11, a rear cover plate 21 and an angle sleeve 31. At the center of one side of the front winding tape 12, there is a front middle column 15. Correspondingly, at the center of one side of the rear cover plate 21, there is a rear middle column 25. The front cover plate 11 and the rear cover plate 21 are fixedly connected through the front middle column 15 and the rear middle column 25. At the same time, the angle sleeve 31 is sleeved at the sharp corners of the front cover plate 11 and the rear cover plate 21 to connect the front cover plate 11 and the rear cover plate 21. A front hairspring 14 is sleeved outside the front middle column 15. Correspondingly, a rear hairspring 24 is sleeved outside the rear middle column 25. The front hairspring 14 and the rear hairspring 24 are respectively connected to the front winding tape 12 and the rear winding tape 22. The front winding tape 12 is wound and disposed around the outside of the front hairspring 14. The rear winding tape 22 is wound and disposed around the outside of the rear hairspring 24. A front opening ring 13 is provided outside the front winding tape 12. The front opening ring 13 is fixedly connected to the front cover plate 11. An opening is provided below the front opening ring 13. Correspondingly, a rear opening ring 23 is provided outside the rear winding tape 22. The rear opening ring 23 is fixedly connected to the rear cover plate 21. An opening is provided above the rear opening ring 23. The front winding tape 12 extends out from the opening of the front opening ring 13. The rear winding tape 22 extends out from the opening of the rear opening ring 23. The front winding tape 12 and the rear winding tape 22 are both the winding tape 32. After the front winding tape 12 and the rear winding tape 22 extend out, they are respectively connected to the winding tapes 32 of different angle devices, forming a demonstration device composed of a number of angle devices and adjacent angle devices connected by the winding tape 32.

[0032] Inside the center of the rear cover plate 21, there is a magnet for adsorbing the angle device on the blackboard.

[0033] A triangular demonstration device composed of three angle devices is used to demonstrate a triangle. By analogy, a quadrangular demonstration device composed of four angle devices is used to demonstrate a quadrilateral.

[0034] After the winding tape 32 is pulled out from the angle device, it is automatically retracted by the pulling force of the front hairspring 14 or the rear hairspring 24.

[0035] When the position of the angle device is fixed, the winding tape 32 cannot be retracted by the pulling force of the front hairspring 14 or the rear hairspring 24.

[0036] As Figures 6-7 shown, after adsorbing three angle devices on the blackboard through the magnets on the rear cover plate 21, various triangles can be formed by moving the angle devices, which is used for explaining to students in class. When two angle devices are moved away from each other, the winding tape 32 wound in the angle device is pulled out to achieve the effect of extending the side of the triangle. At the same time, the front hairspring 14 or the rear hairspring 24 connected by the winding tape 32 is pulled, so that the winding tape 32 obtains the force for retraction to keep the winding tape 32 straight and does not affect the demonstration effect. When two angle devices approach each other, the winding tape 32 is automatically retracted into the angle device by the pulling force of the front hairspring 14 or the rear hairspring 24.

This not only simplifies the operation steps, saves the teaching time of teachers, but also reduces the mistakes in the operation process, making the teaching process smoother. At the same time, the structural design of the device makes it have a certain stability to ensure that the angle device and the tape will not loosen or fall off during the demonstration process.
