Mathematical teaching instrument

Abstract

The invention discloses a mathematical teaching instrument. The mathematical teaching instrument comprises a first fixing component, a supporting component, a connecting component, a first writing board, a second writing board, a third writing board, a second fixing component, a supporting plate, a height adjusting device, a wiping device and a damping device; the supporting plate is slidably connected to the first fixing component; the bottom end of the supporting component is connected with the supporting plate; the top end of the supporting component is connected with the second fixing component; the connecting component is slidably connected with the supporting component; and the connecting component is provided with the first writing board; the first writing board and the third writing board are located on two sides of the first writing board; and the second writing board and the third writing board are both slidably connected with the connecting component. According to the mathematical teaching instrument of the invention, the height adjusting device is adopted, so that the pain of a teacher who bends to write or stands on tiptoe to write can be alleviated; the wiping deviceis adopted, the teacher does not need to manually wipe the writing boards, and the workload of the teacher can be reduced; and the damping device is adopted, so that the stability of the teaching instrument can be facilitated.

Description

technical field [0001] The invention relates to the technical field of mathematics teaching, in particular to a mathematics teaching instrument. Background technique [0002] Mathematics is a subject that studies concepts such as quantity, structure, change, space, and information. From a certain perspective, it is a kind of formal science and is an abstract subject. The rigorous process is the key to mathematical abstraction. It plays an irreplaceable role in the development of human history and social life, and is also an indispensable basic tool for learning and researching modern science and technology; [0003] In mathematics teaching, a large number of calculations are often required, and the teaching staff often need to wipe the writing board frequently, which is very hard, and when writing near the top of the writing board, the teaching staff often needs to write on tiptoe, and when writing near the top of the writing board When writing at the bottom of the board, t...
