Abstract

The invention discloses a geometrical teaching tool, which comprises a first demonstration rod, a second demonstration rod and a rotating shaft, wherein a structure of the second demonstration rod isthe same as that of the first demonstration rod; the first demonstration rod is rotationally connected with the second demonstration rod through the rotating shaft; the first demonstration rod is provided with a geometric drawing demonstration device; the geometric drawing demonstration device comprises a demonstration belt and a first fixing column used for fixing the demonstration belt; one side, facing the first fixing column, of the second demonstration rod is provided with a second fixing column; the demonstration belt is an elastic element. The geometrical teaching tool has advantages ofconveniently describing a drawing, having a simple structure and improving teaching efficiency.

Description

technical field [0001] The invention relates to a teaching tool, in particular to a geometry teaching tool. Background technique [0002] During the teaching process, when teachers are involved in demonstrating geometric figures such as triangles, squares, and rectangles to students, it is difficult to describe the specific geometric figures clearly only by telling them, which makes it difficult for students to understand, thus affecting the quality of teaching; [0003] There are also some teachers who will draw the geometric figure on the blackboard, but the process of drawing will consume a lot of time, time and effort, and seriously affect the teaching efficiency. Contents of the invention [0004] The invention provides a geometric teaching tool, which has the advantages of convenient graphic description, simple structure and increased teaching efficiency. [0005] To achieve the above object, the present invention provides the following technical solutions: [0006...
