Abstract

The invention relates to a drawing board for mathematical education. The drawing board is characterized by comprising a transparent board and a back board which are vertically arranged in the longitudinal direction, wherein a coordinate board in parallel contact with the transparent board is arranged between the transparent board and the back board; moving modules in contact with the back board are mounted on the right lateral side of the coordinate board; each moving module comprises a plurality of fixed frames fixed on the right lateral side of the coordinate board; a rolling wheel which is horizontally or vertically arranged is mounted on the right side of each fixed frame; each rolling wheel is in squeezing contact with the back board; magnetic metal blocks are mounted on the coordinate board; and movable magnetic blocks corresponding to the magnetic metal blocks are arranged on the left side of the transparent board. According to the drawing board disclosed by the invention, the movement of the coordinate board is realized through the two groups of moving modules in different directions, and the coordinate board can be firmly fixed in a motionless state, so that a coordinate system can be provided, and the coordinate board can move or be fixed at any position in a blackboard.

Description

technical field [0001] The invention relates to a mathematical model, in particular to a drawing board for mathematics teaching. Background technique [0002] In the field of mathematics teaching, it is usually necessary to draw various curves to express mathematical formulas or functional relationships. Before drawing curves, it is necessary to draw a coordinate system first. For different mathematical formulas or functional relationships, it is often necessary to draw multiple A coordinate system; and for the same curve or graph, it must be drawn repeatedly in different class hours. This drawing method virtually increases the repetitive work of teachers and students and reduces the teaching speed. Contents of the invention [0003] In view of the above situation, in order to make up for the technical deficiencies in the prior art, the present invention provides a drawing board for mathematics teaching. [0004] The technical solution is to include a transparent board a...
