Problems solved by technology

[0003] In mathematics teaching, when teaching concepts such as various graphics, the shapes of graphics, and the similarity of graphics, if students are directly asked to read textual descriptions, it is more difficult for primary school students, and it is difficult for students to understand the concepts in their minds. The formation of systematic knowledge brings difficulties to students' learning, but primary school students can easily understand and accept the objective things they see
[0004] Now for primary school students better designed mathematical graphics demonstration device, but the existing mathematical graphics demonstration device can not quickly change the mathematical graphics during the demonstration, which is not conducive to the teacher's continuous and rapid mathematical graphics demonstration. The length of the nails is inconvenient to adjust, and the adjacent pegs are easily distributed on the stretched elastic road, which affects the stretching of the elastic band, thereby affecting the mathematical graphics effect of the elastic band demonstration

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a simple mathematical graphic demonstration device. Background technique [0002] Teaching equipment is the general term for all kinds of equipment used to enable students to intuitively and visually understand the teaching content and the equipment used by teachers in teaching. Teaching aids for short. Teaching aids can improve students' interest in learning, enrich perceptual knowledge, help form clear concepts, and develop students' observation and thinking abilities. It is generally divided into three categories: ordinary teaching aids, special teaching aids, and children's teaching aids. [0003] In mathematics teaching, when teaching concepts such as various graphics, the shapes of graphics, and the similarity of graphics, if students are directly asked to read textual descriptions, it is more difficult for primary school students, and it is difficult for students ...
