Abstract

The utility model provides a compound junior mathematics studying card, which consists of a fixed card and a flexible card. Wherein, the upper part and lower part of the flexible card is sealed and the left, right ends are open; the flexible card is inserted into the fixed card from one end of the opening end and can move inside the fixed card. The front face of the fixed card has an opening and the circumference of the opening is printed with contents such as character, symbol and picture. The upper part of the flexible card has a frame which is internally printed with content results corresponding to the opening of the fixed card. Through the movement of the flexible card inside the fixed card, the opening of the fixed card is supper positioned with the frame of the flexible card. The opening position of the fixed card displays the contents or results inside thee frame of the flexible card. The utility model provides the junior mathematics knowledge demonstrated by the teachers in the classes and studied by the students after school.

Description

Combined study card for mathematics in junior middle school

The utility model belongs to the teaching aid technical field, relates to a kind of teaching aid, particularly a kind of combined type Junior Mathematics study card.

Because in the mathematical education of junior high school, with the combined study card demonstrate the speech relevant mathematical phenomenon, such as concept, definition, theorem, kilometer, character, inference, judge, formula, probability, during the ABCs such as function, not only has stronger effect directly perceived, and help Students ' Learning, inquiry, retrieval, review, using institute gains knowledge, improve the ability of students ' understanding things, at present, teacher and student all wishes to have a kind of Combined study card for mathematics in junior middle school urgently, can reach by using, learn, inquiry, retrieval, review, use the relevant knowledge of Junior Mathematics, in order to the teacher modeling speech is provided on the classroom, provide after class the student to use to understand and consolidate the purpose of gaining knowledge, not only can learn Junior Mathematics knowledge well by Help Students, and be that learn each specialty future and Skill Course lays the first stone.

The purpose of this utility model is to provide a kind of combined type Junior Mathematics study card, by teacher's speech of on the classroom, demonstrating, the student is using by starting after school, learn, inquire about, review, use the related subject knowledge of Junior Mathematics, to help the student to improve the quality, increase the ability that solves practical problems.

Task of the present utility model is finished in the following manner: be made up of fixed card, moving card, surely it is closed to block upper and lower formation, left and right open-minded, moving card inserts from one side that fixed card is opened and moves fixed card, can pass through from the another side of opening, its crucial part is to decide to have an opening on the card front at least, and the opening left side or the right or top or bottom are printed in literal or image or symbol or the formula etc. perhaps result.Its crucial part also is, the moving Ding Kanei that is stuck in is when moving, on the moving card corresponding with moving card opening part, be printed on framework with row, framework inside is printed on and blocks in the open circumferential perhaps corresponding result of result or content surely, be stuck in when deciding to move in the card when moving, its different interior perhaps result shows in corresponding opening or shows respectively, so that student's inquiry, retrieval when learning relevant knowledge, review, use.

For guaranteeing that Combined study card for mathematics in junior middle school reaches the modern teaching requirement, moving card and decide card size and can pass through calculative determination, surely blocking opening can be according to the content calculative determination of deciding on card size and the moving card, easy to use for guaranteeing, content is clear eye-catching, result or the content corresponding with the interior perhaps result who decides the card open circumferential, be printed on and decide the card opening with in the corresponding moving card framework of row, when moving card inserts in the moving card, not mobile with no external force, can move to good by means of pulling or pushing away, as for manufacturing material, can manufacture with plastics, also can manufacture with paper products, can use a kind of color, also can be with two or more color, as for adopting which kind of material, color or manufacture, this is selected by manufacturer fully.

Get a fixed card with title, a moving card, to move card and insert fixed card, namely form a Combined study card for mathematics in junior middle school, because same group of Combined study card for mathematics in junior middle school, because through the moving movement that is stuck in Ding Kanei, surely a moving card framework coincidence that blocks opening can be corresponding with same row, mobile moving card can show deciding the card opening moving the interior content results of card framework or content, in conjunction with surely blocking the opening left side or the right or top or following interior perhaps content results, formation asks a question by deciding card, show the result by deciding the card opening by moving card, or propose the result by deciding card, by deciding the card opening by moving card displaying contents.

Below by accompanying drawing shown in the embodiment the utility model is described in further detail.

Fig. 1 is that the moving card of Combined study card for mathematics in junior middle school inserts surely block schematic diagram fully;

Fig. 2 is that Combined study card for mathematics in junior middle school surely blocks the 2nd row of openings and overlaps schematic diagram with moving card the 2nd row's framework;

Fig. 3 is that Combined study card for mathematics in junior middle school surely blocks the 3rd row of openings and overlaps schematic diagram with moving card the 3rd row's framework.

With reference to Fig. 1, moving card (5) inserts fixed card (1) fully, Ding Kadi 2 rows and the 3rd row of openings (3), (4), can't show the content in moving card framework (7), (8), surely block opening the 1st row of openings (2) and overlap, block the 1st row of openings (2) surely and show the content of moving in card the 1st row's framework (6) with moving card opening the 1st row's framework (6).

With reference to Fig. 1, Fig. 2, moving card (1) position of to Fig. 2 fixed card (9) and moving card (13) that moves right among Fig. 1, Ding Kadi 1 row of openings (10) can't show the content in the moving card framework (14), Ding Kadi 3 row of openings (12) can't show the content in the moving card framework (16) equally, Ding Kadi 2 row of openings (11) overlap with moving card the 2nd row's framework (15), block the 2nd row of openings (11) surely and show the content of moving in card the 2nd row's framework (15).

With reference to Fig. 1, Fig. 2, Fig. 3, moving card (13) moves right and blocks the position of (17) and moving card (21) to Fig. 3 surely among Fig. 2, Ding Kadi 1 row of openings (18) can't show the content in moving card the 1st row's framework (22), Ding Kadi 2 row of openings (19) can't show the content in moving card the 2nd row's framework (23), Ding Kadi 3 row of openings (20) overlap with moving card the 3rd row's framework (24), Ding Kadi 3 row of openings (20) show the moving interior content of the 3rd row's framework (24) of blocking, and moving card (21) recovers virgin state after moving to the position of deciding card (1) and moving card (5) among Fig. 1 among Fig. 3.

The utility model has not only utilized discrete original paper by the synthetic learning card of set of displacements, and opening and framework have been equipped with, make teacher's demonstration speech and student's the foundation of having started theory and having tested, filled up the blank of combined study card teaching aid in the mathematical education of junior high school, for the junior high school learning mathematics provides a kind of desirable teaching aid.

The utility model can adopt plastics to manufacture, and also can adopt paper products and manufacture, and it is very easy to produce, and is the desirable teaching aid of mathematics teaching in junior middle school and Students ' Learning Junior Mathematics knowledge.
