Polygonal dynamic demonstration teaching aid

Abstract

A polygonal dynamic demonstration teaching aid, comprising a plurality of rulers (1); each ruler is provided with a through slot (11) in the middle along the length of the ruler; the through slot (11) is installed with a plurality of sliders (2, 2') slidable in the through slot (11); a slider (2, 2') is provided with a connection peg (25, 25') at the top and a socket hole (26, 26') at the bottom mating with a connection peg (25, 25'). The rulers (1) can be stacked, and the sliders (2, 2') thereof can be superimposed on one another and combined together, so that the rulers (1) can be assembled into various kinds of polygons. During demonstration of the teaching aid, the upper and lower rulers (1) can be stacked or separated as desired so as to form various kinds of intuitive polygons. The rulers (1) feature simple and time-saving assembly and disassembly and convenient usage, can reduce the plotting workload of a user or a teacher, and can also cultivate the ability of students in thinking, association and analogy, and observation, spark the imagination and arouse the interest of students in learning geometry.

Description

technical field [0001] The invention relates to a geometric dynamic demonstration teaching aid, in particular to a polygonal dynamic demonstration teaching aid. Background technique [0002] At present, in geometry teaching, teaching aids generally include rulers, triangles, etc. When teaching drawing, teachers can only draw the graphics they need step by step on the basis of online. The drawing process is cumbersome and not intuitive. Teachers must Drawing and talking are very busy, and at the same time, students' association, analogy, observation and hands-on ability cannot be well cultivated, which will inevitably affect the effect of geometry teaching. Moreover, there are many disadvantages in themselves: it is inconvenient to carry, it is also inconvenient to use, and more importantly, it has a single function.

[0002] At present, in geometry teaching, teaching aids generally include rulers, triangles, etc. When teaching drawing, teachers can only draw the graphics they need step by step on the basis of online. The drawing process is cumbersome and not intuitive. Teachers must It is very busy to draw and talk, and at the same time, it cannot cultivate students' association, analogy, observation and hands-on ability, which will inevitably affect the effect of geometry teaching

Moreover, there are many disadvantages in themselves: it is inconvenient to carry, it is also inconvenient to use, and more importantly, it has a single function.

[0003] On the other hand, although the existing geometric teaching aids can intuitively demonstrate geometric figures, there are relatively few figures that can be demonstrated, and the scope of use is relatively narrow

[0004] Moreover, some geometric teaching aids are connected by butterfly bolts or nuts, which are cumbersome and time-consuming to assemble and disassemble, which affects the continuity of teaching demonstrations.
