Abstract
The utility model discloses a math teaching aid, which comprises a square tray made of steel, and three crossbeams are arranged in the square tray to divide the square tray into four panes, i.e. a first operation pane, a second operation pane, a symbol pane and an answer pane which are arranged sequentially from the top down. When in use, the square tray is vertically hung on a wall or a blackboard, the numerical relationship and the problem correlation pattern in a mathematical problem can be demonstrated by respectively placing operation blocks, symbol blocks and answer blocks in corresponding areas, and the learning initiative of students can be sufficiently activated as well.
Description
Technical field
The utility model relates to a kind of teaching aid, relates to a kind of mathematical education instrument specifically.
Background technology
At present, mostly widely used mathematical education apparatus is to adopt simple model such as some wall charts, card and stereoscopic model.Wall chart is many based on static state, and it is bigger to take up space, and when running into the problem of difficulty, then needs multiple hanging chart, and it is single therefore to exist usability, carries inconvenient problem.Though the stereoscopic model teaching aid can solve the problem of three-dimensional aspect, limitation is very strong, often model teaching aid can only solve a problem and also volume and weight bigger than normal, also be unfavorable for carrying and using.And teaching card lacks vividness because of it, and can't cause students'interest in learning, and card is very scattered very again, also loses easily, causes the incompleteness of card.In addition, because existing teaching aid can't simply be demonstrated out quantitative relation, the showing problem correlation form of mathematical problem, therefore, when running into this kind problem, the teacher often can't be lively to this kind problem interpretation and explanation, also cause the student when understanding this kind problem, to be easy to cause mistaken ideas.
The utility model content
Problem to be solved in the utility model provides a kind of project organization advantages of simple, characteristics with polytrope and novelty, quantitative relation and showing problem correlation form in the mathematical problem can be demonstrated, and the mathematical education instrument of students ' enthusiasm can be given full play to.
In order to address the above problem, the technical solution adopted in the utility model is:
A kind of mathematical education instrument comprises a square plate made from steel material, is provided with three road crossbeams in square plate, and three road crossbeams are followed successively by the first computing frame, the second computing frame, symbol frame and answer frame from top to bottom with four districts, square plate interval frames.
Below be the utility model for further improvement of these options:
Vertically be provided with one dividing plate in the described square plate, dividing plate and beam vertical are arranged in a crossed manner.
Further improve: described dividing plate is separated into computing district and operation blocks storage area respectively with the first computing frame and the second computing frame, is placed with several operation blocks in the operation blocks storage area, has the passage with computing district and the connection of operation blocks storage area on the dividing plate.
Further improve: described dividing plate is separated into sign field and symbol store with the symbol frame, is placed with the symbolic blocks made from magnet in the symbol store, has the passage with sign field and symbol store connection on the dividing plate.
Further improve: described dividing plate is separated into answer district and answer piece storage area with the answer frame, offers the passage with answer district and the connection of answer piece storage area on the dividing plate, is placed with the answer piece that several are made with magnet in the answer piece storage area.
During use, this square plate vertically hung on the wall or on the blackboard, by with operation blocks, symbolic blocks and answer piece respectively correspondence be placed on corresponding zone, can either demonstrate quantitative relation and showing problem correlation form in the mathematical problem, can give full play to students ' enthusiasm again.
The utility model is described in further detail below in conjunction with drawings and Examples:
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
Among the figure: the 1-square plate; 2-computing district; The 3-sign field; The 4-crossbeam; 5-answer district; The 6-dividing plate; 7-operation blocks storage area; The 8-operation blocks; The 9-symbol store; The 10-symbolic blocks; 11-answer piece storage area; The 12-passage; 13-answer piece.
Embodiment
Embodiment, as shown in the figure, a kind of mathematical education instrument, comprise a square plate 1 made from steel material, in square plate 1, be provided with three road crossbeams, 4, three road crossbeams 4 with four districts, square plate 1 interval frames, be followed successively by the first computing frame, the second computing frame, symbol frame and answer frame from top to bottom; Vertically be provided with dividing plate 6 in the square plate 1 one, dividing plate 6 and crossbeam 4 square crossing settings, described dividing plate 6 is separated into computing district 2 and operation blocks storage area 7 respectively with the first computing frame and the second computing frame, in operation blocks storage area 7, be placed with several operation blocks 8, have passage 12 on the dividing plate 6 computing district 2 and 7 connections of operation blocks storage area; Described dividing plate 6 is separated into sign field 3 and symbol store 9 with the symbol frame, is placed with the symbolic blocks made from magnet 10 in the symbol store 9, has the passage 12 with sign field 3 and symbol store 9 connections on the dividing plate 6; Described dividing plate 6 is separated into answer district 5 and answer piece storage area 11 with the answer frame, has the passage 12 with answer district 5 and 11 connections of answer piece storage area on the dividing plate 6, is placed with the answer piece 13 that several are made with magnet in the answer piece storage area 11.
During use, this square plate 1 vertically hung on the wall or on the blackboard, by with operation blocks 8, symbolic blocks 10 and answer piece 13 respectively correspondence be placed on corresponding zone, can either demonstrate quantitative relation and showing problem correlation form in the mathematical problem, can give full play to students ' enthusiasm again.
