Mathematics teaching board

Abstract

The invention discloses a mathematics teaching board. The mathematics teaching board comprises a base, wherein two thread rods are symmetrically screwed to the edge of the base; the bottom ends of thethread rods penetrate through the base and are fixedly connected with the top end of a support seat; an anti-slide pad is attached to the bottom surface of the support seat; universal wheels are installed at the bottom end of the base; a hydraulic telescopic rod is fixedly arranged at the top end of the base; the hydraulic telescopic rod is connected with a hydraulic station through a pipeline; the hydraulic station is electrically connected with a hydraulic controller; and the hydraulic station and the hydraulic controller are fixedly arranged on the base. The mathematics teaching board disclosed by the invention can be freely moved to any position through the universal wheels, and can also be freely rotated and ascended or descended, so that more convenience is brought to a teacher in aprocess of drawing a geometric graph or drawing a function curve; a red board is used as a rear board, and a blackboard eraser capable of telescoping and freely rotating is adopted, so that the teacher is facilitated to use the blackboard eraser for erasing the unneeded contents in the teaching board; and moreover, due to the arranged angle scale and coordinate system board, the teacher is much facilitated to draw the geometric graph and the function curve, so that more time is saved.

Description

technical field [0001] The invention relates to the field of mathematics teaching supplies, in particular to a mathematics teaching board. Background technique [0002] The teaching board is the utensil used for writing demonstrations in the education industry. Usually, the teaching board is a board placed in a classroom or a meeting room, and the content is written with chalk or water-based pen to play the role of explaining and demonstrating. [0003] Mathematics is a subject that studies concepts such as quantity, structure, change, space, and information, and it is a kind of formal science from a certain perspective. [0004] It takes a long time for the teacher to draw geometric figures on the teaching board in the classroom. The existing teaching board cannot be disassembled or moved, so the teacher cannot draw the geometric figures before class, which seriously leads to a waste of classroom teaching time, and the mathematics teacher explains geometry. When drawing gr...

[0004] It takes a long time for the teacher to draw geometric figures on the teaching board in the classroom. The existing teaching board cannot be disassembled or moved, so the teacher cannot draw the geometric figures before class, which seriously leads to a waste of classroom teaching time, and the mathematics teacher explains geometry. When drawing graphics or geometric functions, they will use compass, ruler, protractor or triangular ruler to draw pictures. Mathematics teachers often want to make geometric figures or function curves better express what they are talking about, which leads to the need for Changing a variety of tools to make regular graphics will seriously affect the efficiency of lectures, resulting in a lot of time wasted, and the existing mathematics teaching board teachers may make mistakes or need to draw the next graphic or function curve during the writing process. The teaching board is wiped out, but often the teacher needs to go to another place to find it when using it, which seriously affects the teaching efficiency
