Rotary magnetic solid geometry figure demonstration device

Abstract

The invention relates to a rotary magnetic solid geometry figure demonstration device. The rotary magnetic solid geometry figure demonstration device comprises a bottom plate, a supporting device, a pedal device, a fixing plate and a demonstration device body, wherein the upper end of the bottom plate is symmetrically provided with universal wheels, the middle of the upper end of the bottom plateis provided with the supporting device, the right side of the upper portion of the bottom plate is provided with the pedal device, the pedal device cooperates with the middle of the supporting device,the upper end of the supporting device is provided with the fixing plate, and the upper end of the fixing plate is provided with the demonstration device body. The rotary magnetic solid geometry figure demonstration device has the advantages that the problem is solved that when existing teachers perform solid figure teaching on middle school students, the teachers are usually only able to teach conceptual knowledge, however, due to the limited spatial imagination abilities of the students, it is difficult for the students to understand conceptual figures expressed by the teachers and to imagine the complete figures, the function of demonstrating different solid geometry figures can be achieved, the specific demonstration effect is good, the use and operation are simple and convenient, theinterestingness of attending class is increased, and learning and understanding of the students are facilitated.

Description

Technical field [0001] The invention relates to the field of teaching aids, in particular to a rotating magnetic three-dimensional geometric figure display device. Background technique [0002] There are geometric figures everywhere in life, and everything we see is composed of basic geometric figures such as points, lines, and surfaces. In the learning process of middle school mathematics, three-dimensional geometric figures often appear. For students who are new to three-dimensional figures, they are often more difficult to understand abstract concepts. [0003] At this stage, when teaching three-dimensional graphics to students, there are usually the following shortcomings: 1. The teacher can usually only teach conceptual knowledge, but the students have limited spatial imagination ability, it is difficult to understand the conceptual graphics expressed by the teacher, and cannot be complete. Imagine the graphics; 2. The existing teaching devices have poor display effects and c...

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a rotating magnetic three-dimensional geometric figure display device. The present invention can solve the problem that when the existing teachers teach three-dimensional figures to middle school students, the teacher usually can only teach conceptual knowledge. Space imagination is limited, it is difficult to understand the conceptual graphics expressed by the teacher, and it is impossible to imagine the graphics completely. It can realize the function of displaying different three-dimensional geometric figures. The specific display effect is good, the operation is simple and convenient, and the class is increased. Interesting, easy for students to learn and understand
