Polygonal dynamic demonstration teaching aid

Abstract

The invention relates to a polygonal dynamic demonstration teaching aid which comprises a plurality of rulers, a through groove is formed in the middle of each ruler in the length direction, a plurality of sliders are installed in each through groove, the sliders can slide in the through grooves, an inserting connection post is arranged on the top of each slider, a sleeved connection hole which can be matched with each inserting connection post is formed in the bottom of each slider, the rulers can be vertically folded, the sliders can be mutually and vertically overlapped and combined together, and thereby the plurality of rulers can be combined into various polygonal shapes. In demonstration, the upper ruler and the lower ruler can be overlapped or separated according to requirements and form various intuitive polygons in an assembling mode. Assembly and disassembly of the rulers are simple, time-saving and convenient. Drawing workload of a user or a teacher can be reduced, students can further cultivate abilities such as thinking, association, analogy and observation, imagination of the students is aroused, and interest of learning geometry of the students is improved.

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.
