A Mathematical Model Demonstration Teaching Aid

Abstract

The invention discloses a mathematical model demonstration teaching aid, which comprises a display screen body (1). The upper and lower sides of the two ends of the display screen body (1) are respectively provided with positioning ear seats (2), and the two positioning ear seats at the same end (2) are installed with the rotating shaft (3) that is connected with its rotation, and between the two rotating shafts (3) at the two ends of the display screen body (1) is provided with a circle of soft glass (4) that fits its outer circular surface. The invention has a simple structure. When in use, the map template of the mathematical model can be projected on the display screen body, and then each data can be gradually filled on the soft glass, which can be filled in while explaining, thereby greatly improving the teaching effect. In the next class, start the driving motor, and some pasted teaching aids attached to the soft glass will be scraped into the storage cavity through the partition, and when the soft glass enters the character erasing cavity, it can be wiped away by the character erasing roller. Ink stains on the surface are wiped away.

Description

technical field [0001] The invention relates to the field of teaching aids, in particular to a mathematical model demonstration teaching aid. Background technique [0002] In the process of teaching mathematical models, teachers often need to draw corresponding model maps on the blackboard. Drawing such model maps is not only very troublesome, but also seriously delays the overall teaching progress and efficiency. The current methods for this problem are all The slides are used in the classroom, but during the teaching process, the slides cannot be written correspondingly with the changes of the teaching progress, but are displayed all at once, so the teaching effect is also poor. Contents of the invention [0003] The purpose of the present invention is to provide a mathematical model demonstration teaching aid, which can effectively solve the problems existing in the background technology. [0004] In order to solve the problems existing in the background technology, it...
