Abstract
The utility model discloses an advanced mathematics education plate which comprises a lamp box and a base. The advanced mathematics education plate further comprises a plurality of transparent ground glass plates. The front face and the rear face of the lamp box are grid light-pervious screens. A beam is arranged at the top of the lamp box. Two side walls of the beam are respectively and symmetrically provided with a hanging rod. Each ground glass plate is provided with a hanging ring. The ground glass plates are respectively arranged on the front face and the rear face of the lamp box in a hung mode and are attached to the grid light-pervious screens. The periphery side walls of the ground glass plates are covered by protective sleeves. The advanced mathematics education plate is simple in structure, strong in practicality and effective in specifying drawing standards. According to the advanced mathematics education plate, education quality is improved, meanwhile the front face and the rear face of the lamp box can be repeatedly used, the lamp box and the grid light-pervious screens can improve accuracy degree of drawing, students can be further enabled to see the advanced mathematics education plate clearly, time is greatly saved, and education effect is greatly improved.
Description
Technical field
The utility model relates to a kind of mathematics teaching aid, and relates more specifically to a kind of Higher Mathematics Teaching plate.
Background technology
In College Mathematics Teaching, often need to draw some figures, curve etc. at blackboard, owing to not having coordinate, grid on the existing blackboard, increased the difficulty that the teacher draws, and there is larger error in the figure of drawing, cause the shape of function curve inaccuracy, figure inaccurate, can affect the visual experience of study, further cause teaching efficiency relatively poor.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of Higher Mathematics Teaching plate.
To achieve these goals, the technical solution adopted in the utility model is: a kind of Higher Mathematics Teaching plate, comprise lamp box and base, also comprise the focussing glass that several piece is transparent, the front and back of described lamp box is the grid light transmission screen, and the top of described lamp box is provided with crossbeam, and the two side of described crossbeam is arranged with respectively peg, described focussing glass is provided with link, and described focussing glass hangs up respectively in the front and back of lamp box and with the grid light transmission screen and fits.
As preferably, sidewall is coated with protective sleeve around the described focussing glass.
As preferably, described peg is two groups.
As preferably, all mate described link and peg shape size position.
Compared with prior art, the utility model has the advantage of: simple in structure, practical, effectively standard the standard of drawing, improved quality of instruction, can repeatedly use by positive and negative simultaneously, lamp box and grid light transmission screen can improve the degree of accuracy of drawing, can also allow the student is clearer to see board of education clearly, save greatly the time and improved teaching efficiency.
