Abstract
The utility model discloses a magnetic quadrilateral plate serving as a teaching aid. The magnetic quadrilateral plate comprises quadrilateral plates and cylindrical magnets, the quadrilateral plates with the cylindrical magnets are divided into two groups, each group includes six quadrilateral plates, four cylindrical magnets are arranged around the edge of each quadrilateral plate, and S poles and N poles of the magnets are opposite. The magnetic quadrilateral plate is convenient for a primary or secondary school teacher to show characteristics and structures of a square, a rectangle, a cube and a cuboid and the method of calculating volume and surface area. In teaching demonstration, the quadrilateral plates can be freely placed according to teaching content, both hands of a presenter can be fully liberated, so that the teaching demonstration is simpler and easier to operate.
Description
Technical field
The utility model discloses a kind of how much teaching aids, is a kind of magnetic quadrangular plate specifically, belongs to the teaching aid category.
Background technology
Existing quadrilateral teaching aid; Have only a simple plate, will be between teaching demonstration mesoplate and plate by holding with hand steered, other actions are done in both hands inconvenience again; Teaching demonstration can not be brought into play vivider lively effect, and the value of teaching aid can not better be showed.
Summary of the invention
In view of above drawback, the design proposal of the utility model is disclosed to be a kind of magnetic quadrangular plate teaching aid, utilizes it can make things convenient for teachers in primary and middle schools to demonstrate square, rectangle, square, the method for the characteristic of rectangular parallelepiped, structure and volume calculated and surface area.
The utility model is realized with following technical scheme: a kind of magnetic quadrangular plate; Constitute by quadrilateral sheet material and cylinder-shaped magnet; Six square plates that are provided with cylinder-shaped magnet are one group, and totally two groups, described cylinder-shaped magnet is arranged on the edge of quadrangular plate; Be provided with four, the extremely reciprocal setting of the S of magnet, N around the every quadrangular plate.
The beneficial effect of the utility model is: the utility model is one group of quadrangular plate that has magnetic attraction; In teaching demonstration, only need plate freely be put according to the content of courses, can fully liberate the both hands of demonstrator; Make teaching demonstration simpler, more easily operation.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1 quadrilateral plate, 2 cylinder-shaped magnets.
Embodiment
As shown in the figure; The utility model comprises quadrilateral plate 1 and cylinder-shaped magnet 2, and cylinder-shaped magnet 2 is arranged on the edge of quadrilateral plate 1, is provided with four cylinder-shaped magnets 2 around the every quadrangular plate 1; The extremely reciprocal setting of the S of cylinder-shaped magnet 2, N; Per 6 square plates by quadrilateral plate 1 and cylinder-shaped magnet 2 combinations are one group, and totally two groups, the edge-to-edge who needs only two square plates in the process of teaching demonstration pastes suction together.Simple in structure, easy to operate.Suitable teachers in primary and middle schools demonstrate square, rectangle, square, the method for the characteristic of rectangular parallelepiped, structure and volume calculated and surface area.
