Abstract

The utility model is a novel magnetic-sticking coordinate blackboard, which adopts a ferruginous blackboard which is drawn with the coordinate planes by the dope combined with a soft stripe magnetic sticking and a plurality of specially designed small blocks of magnetic sticking with the attached graphs to realize the random sticking of the axis of abscissa, the axis of ordinate and the movable graphs according to the needs of the teaching content, which is good for enhancing the demonstrating performance in the process of teaching and making the explained knowledge more clear.

Description

Magnetic pastes Blackboard with coordinate

Technical field

The utility model relates to-kind of the blackboard that uses in teaching process, particularly is aided with on the irony blackboard of coordinate grid that various magnetic paste and the teaching of removable reference axis is pasted Blackboard with coordinate with magnetic drawing.

Background technology

For a long time, teacher feels inconvenience deeply when explaining relevant knowledge such as mathematics/physics on drafting has the blackboard of coordinate grid, and this is because when needing mobile axis of abscissas or axis of ordinates whenever, wipe old line and draw ew line and be in the way very much.Upward demonstration is handy certainly at computer (computer) now, but this will enable the projection giant-screen and be shown and could realize, and China's national situation also can not allow every-classroom of all middle and primary schools all be equipped with large screen projection formula computer equipment in a short time, and most classrooms rely on traditional blackboard to use the carrier of drawing medium as teaching in long-term very the time.

Summary of the invention

The purpose of this utility model provides-the magnetic paster type Blackboard with coordinate of kind of novelty, its vertical/axis of abscissas and-a little special figures that make all can arbitrarily move and put, make demonstration operation in the teaching process fast and allow the knowledge set forth more fast, more clear.

The utility model solves this-and technical scheme that technical problem adopted is: on special blackboard, drawn grid square earlier with permanent coating, and axis of abscissas and axis of ordinates all adopt soft stripe shape magnetic subsides to make, special again-a little fritter magnetic paste, these little magnetic stick the figure that can stick paper temporarily as required on its surface and paint (as car/ship/house/other or the like), because have magnetic, reference axis and little magnetic paste all can be optionally " stickups " optional position on Blackboard with coordinate, certain employed blackboard should adopt the current irony plastic-blasting blackboard that is generally being used by middle and primary schools.

Does what material claim to be pasted for magnetic? originally it is to have mixed into magnetic powder in the flexible macromolecule plastics, be pressed into required lamella shape then, at present a large amount of already cartoon toys that have been made into are not used for teaching as yet, but this type of magnetic pastes and can be widely used in fully among the teaching.

The beneficial effects of the utility model are: its reference axis and ad hoc figure all can be on blackboard arbitrarily move, " stickups " and take off, thereby make the demonstration of some teaching process operate quick and make the knowledge set forth more clear.

Description of drawings

The explanation of the utility model being done into-being gone on foot below in conjunction with drawings and Examples.

Fig. 1 is that the utility model magnetic pastes the Blackboard with coordinate structural representation.

Among Fig. 1: 1-has been painted with the irony blackboard surface of coordinate grid; 2-does the stripe shape magnetic subsides that axis of ordinates is used; 3-does the stripe shape magnetic subsides that axis of abscissas is used; The little magnetic that 4-is illustrated as " house " pastes (exemplifying); The little magnetic that 5-is illustrated as " big tree " pastes (exemplifying).

The specific embodiment

Earlier on special blackboard, drawn grid square with permanent coating; Long strip type magnetic is pasted again and cut out out long two joints on demand, the surface is coated with gay colours, and-end is made arrowhead form, and this is as vertical/axis of abscissas; Again slim magnetic paster is cut the required figure of room/tree or the like, be coated with on its surface, for desiring the object of displaing coordinate with different color (or being stained with certain Pattern paste paper); Our described magnetic pastes Blackboard with coordinate and just can come into operation.During use according to the needs of the content of courses can be at any time with the explanation process with any translation of reference axis, perhaps will shown in the random shift position of object and arbitrarily " stickup " or take off.

Claims

1. magnetic paster type Blackboard with coordinate, it is characterized in that: on the irony blackboard, drawn grid square with permanent coating, stripe shape magnetic with softness pastes making axis of abscissas and axis of ordinates, and the more special fritter magnetic that can temporarily stick paper drawing shape as required on its surface pastes.
