Abstract
A plane geometry demonstration teaching aid belongs to the field of the auxiliary teaching tool and aims to solve the problem that the teaching result is affected because the teacher must stand in the front left side or the front right side of a conventional demonstration teaching aid so as to operate the teaching aid during the presentation process of the conventional plane geometry demonstration teaching aid. The plane geometry demonstration teaching aid of the utility model comprises a demonstration board and a magnetic component; the demonstration board consists of flat glass and spherical glass; the flat glass is a square, and the diameter of the spherical glass is larger than the side length of the flat glass; the flat glass and a concave surface of the spherical glass are oppositely arranged and the center of each other are aligned; the four corners of the flat glass are fixed with the corresponding positions on the edge of the spherical glass positions through connecting pieces; a plane coordinate system or grid lines are engraved on the flat glass; the magnetic component comprises a plurality of magnets and a plurality of thin iron wires; the plurality of magnets are magnetically fixed on the front side and the back side of the flat glass in pairs; and the plurality of thin iron wires are absorbed on the magnet on the back side of the flat glass. The plane geometry demonstration teaching aid is used to demonstrate the plane geometry teaching content.
Description
Technical field
The utility model belongs to the teaching tool field, is specifically related to a kind of plane geometry demonstration teaching aid.
Background technology
Current plane geometry demonstration teaching aid is in presentation process, and front left side or forward right side that the teacher will stand in demonstration teaching aid are operated teaching aid, often block part student's sight line, makes the part student can't see demo content, affects teaching efficiency.
Summary of the invention
The purpose of this utility model is in order to solve current plane geometry demonstration teaching aid in presentation process, front left side or forward right side that the teacher will stand in demonstration teaching aid are operated teaching aid, affect the problem of teaching efficiency, a kind of plane geometry demonstration teaching aid is provided, its technical scheme is as follows:
A kind of plane geometry demonstration teaching aid, it comprises demonstration board and magnet assembly; Described demonstration board consists of flat glass and spherical glass, flat glass is square, the diameter of spherical glass is greater than the length of side of flat glass, the concave surface of flat glass and spherical glass is oppositely arranged and center-aligned, the position corresponding with spherical glass edge, four jiaos of places of flat glass is fixedly connected with web member, is carved with plane coordinate system or mesh lines on flat glass; Described magnet assembly comprises polylith magnet and Duo Gen thin wire, and polylith magnet is corresponding in twos to be fixed on the two sides, front and back of flat glass with magnetic force, and many thin wires are inhaled and put down on the magnet of glass back.
The beneficial effects of the utility model are: the teacher may stand in the demonstration teaching aid back and demonstrates operation, can not block student's sight line, improves teaching efficiency.
the accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side schematic view of the present utility model.
embodiment:
See figures.1.and.2, a kind of plane geometry demonstration teaching aid, it comprises demonstration board 1 and magnet assembly 2; Described demonstration board 1 consists of flat glass 1-1 and spherical glass 1-2, flat glass 1-1 is square, the diameter of spherical glass 1-2 is greater than the length of side of flat glass 1-1, the concave surface of flat glass 1-1 and spherical glass 1-2 is oppositely arranged and center-aligned, the position corresponding with spherical glass edge, four jiaos of places of flat glass 1-1 is fixedly connected with web member, is carved with plane coordinate system or mesh lines on flat glass 1-1; Described magnet assembly 2 comprises polylith magnet 2-1 and Duo Gen thin wire 2-2, and polylith magnet 2-1 is corresponding in twos to be fixed on the two sides, front and back of flat glass 1-1 with magnetic force, and many thin wire 2-2 inhale and putting down on the magnet of glass back.
Preferably, in described spherical glass 1-2 lower end, be provided with sucker 1-3, in described flat glass 1-1 lower end, two pillar 1-4 be set, the lower end of two pillar 1-4 is provided with sucker 1-3.
The using method of utility model and principle: be placed on corresponding support by the utility model or stand on the table, take polylith magnet 2-1 as point, the many thin wire 2-2 of take are line, the content that demonstration needs, owing to adopting glass to do demonstration board, so may stand in the utility model back, the teacher demonstrated, can not block student's sight line, spherical glass 1-2 has to amplify and does use, makes that the student is clearer sees demo content.
