A teaching aid for mathematics

Abstract

A teaching aid for mathematics, relating to a teaching tool, a trapezoidal horizontal plate is arranged on the upper part of the blackboard, a slideway is provided on the lower surface of the trapezoidal horizontal plate, and a A sliding card release part with clearance fit, the sliding card release part is composed of a sliding rod and an L-shaped card release rod, and the sliding card release part performs clearance fit with the slideway on the lower surface of the ladder horizontal plate through the sliding rod, An L-shaped card release rod that fits in a gap with the slide rod is provided in the slide rod, and a double-sided writing display board is placed in the L-shaped card release rod; not only can the double-sided writing display board be realized Quick and effective card installation, adjust the position of the double-sided writing display board according to the actual situation, so as to avoid affecting the normal use of the blackboard, and it can also greatly facilitate the teacher to quickly draw the coordinate system in class, greatly reducing the time spent in class. The drawing time is reduced, which effectively improves the teaching quality.

Description

technical field [0001] The invention relates to a teaching aid, in particular to a mathematics teaching aid. Background technique [0002] Mathematics is the foundation of all sciences. Behind every major progress of mankind is the strong support of mathematics. Mathematics has penetrated into various fields of natural science and social science. The use of mathematics can help people process data, perform calculations, reasoning and proof; mathematics is also a tool subject and the basis for learning other subjects. Often breakthroughs in mathematics will lead to major breakthroughs in many other disciplines. According to the traditional teaching methods, most of the teachers speak and the students listen. The students' mathematics learning effect has a lot to do with the teaching methods, so mathematics teaching is very important. In the process of mathematics teaching, teachers usually use some teaching aids to assist the completion of teaching tasks. Researching a tea...

Problems solved by technology

Mathematical formulas are the basis of mathematical problem solving, and during the learning process, there are many mathematical formulas, and some formulas are too similar. If the memory is not accurate, it is difficult to solve the problem correctly

The existing small blackboard is inconvenient to carry, and there are still some problems in the process of use, which cannot achieve the expected auxiliary teaching effect. The specific problems are as follows:

[0004] 1. In the current mathematics learning process, in order to avoid wasting time due to blackboard writing and make full use of classroom time, teachers usually write the content to be explained in class on the small blackboard in advance, and carry it into the classroom for hanging teaching during class. However, a lot of time There is no convenient place to hang the small blackboard in the classroom. Usually, the teacher puts the small blackboard on the desk to explain, which is very inconvenient

[0005] 2. Most of the small blackboards used in mathematics classrooms are hung above the blackboard by nails. However, due to the high nails on the top of the blackboard, it is difficult for many teachers to hang the blackboard quickly and effectively, and sometimes they need to step on the stool for hanging. very inconvenient

[0006] 3. When writing or drawing on the hanging small blackboard, since the small blackboard is hung on the wall by nails, it is difficult for a teacher with a short height to write comfortably and conveniently, and the small blackboard is only hung on the wall by nails , which makes it easy to shake, so that teachers sometimes need to hold the small blackboard with one hand and write with the other, which is very inconvenient to write

[0007] 4. The small blackboards currently used are generally hung on the nails on the wall and cannot be moved, which will cause the small blackboard to cover the blackboard, which not only occupies the applicable area of ​​the blackboard, but also is inconvenient for the teacher to write on the blackboard in class

[0008] 5. Due to the small size of the small blackboard and the high hanging position, when it is hung on the side of the wall, it is easy for some students to be unable to see the content on the small blackboard due to reflection, which is not conducive to students' learning

[0009] 6. Mathematics teachers will need to draw a rectangular coordinate system for teaching when teaching, especially when teaching functions. However, drawing a rectangular coordinate system not only requires the teacher to carry a drawing tool, but also drawing is very time-consuming and laborious, which takes up a lot of class time. teaching time on
