Abstract
The utility model discloses a demonstration plate for teaching mathematical addition and subtraction in a school for deaf-mutes, which comprises a bottom plate made of a magnetic material. The periphery of the bottom plate is provided with a frame. The bottom plate is provided with a first longitudinal partition plate and a second longitudinal partition plate. The two ends of the first longitudinal partition plate and the two ends of the second longitudinal partition plate are connected with the frame respectively. The bottom plate is spaced into a digital block storage area, a digital block combination area and a symbol area by the two ends of the first longitudinal partition plate and the second longitudinal partition plate. A plurality of digital blocks marked with a single number or a single symbol respectively and made of a magnetic material are arranged in the digital block storage area. The part of the bottom plate, which is positioned within the digital block combination area, is provided with two transverse partition plates. One ends of the transverse partition plates are connected with the first longitudinal partition plate, while the other ends of the transverse partition plates are connected with the second longitudinal partition plate. The digital block combination area is spaced into a first digital block combination area, a second digital block combination area and an answer demonstration area by the two transverse partition plates. The first digital block combination area, the second digital block combination area and the answer demonstration area are arranged in an up-and-down direction. The demonstration plate has the advantages of simple structure and convenient use.
Description
Technical field
The utility model relates to a kind of mathematics plus-minus method demonstration board, and particularly a kind of mathematics plus-minus method demonstration board that is used for school for deaf-mutes's teaching belongs to the teaching aid field.
Background technology
At present; In the primary school mathematics plus-minus method teaching process of school for deaf-mutes; Because the student of school for deaf-mutes can not listen or say, can only improve deaf and dumb student's memorizing in images ability with visual illustration, but primary school mathematics plus-minus method teaching now usually is to let number of students finger etc.; Operation very bothers, wastes time and energy, and has increased great work difficulty to teaching.
The utility model content
The problem that the utility model will solve provide a kind of easy to operate, can be in the primary school math teaching process with the mathematics plus-minus method demonstration board that is used for school for deaf-mutes teaching of integrating theory with practice.
In order to address the above problem, the utility model adopts following technical scheme:
A kind of mathematics plus-minus method demonstration board that is used for school for deaf-mutes's teaching comprises the base plate of processing with magnetic material, has frame around the said base plate, and said base plate is provided with first longitudinal baffle and second longitudinal baffle; The two ends of the two ends of first longitudinal baffle and second longitudinal baffle are connected with frame respectively; The two ends of first longitudinal baffle and second longitudinal baffle are partitioned into digital block storage area, digital block combination region and sign field with base plate, are placed with the digital block of processing with magnetic material that several are marked with individual digit or symbol in the digital block storage area.
The position that is positioned at the digital block combination region on the base plate is provided with the twice lateral partitions; One end of lateral partitions is connected with first longitudinal baffle, the other end is connected with second longitudinal baffle, and the twice lateral partitions is partitioned into the digital block combination region in the first digital block combination region, the second digital block combination region and the total demonstration district that is arranged above and below.
During teaching; The digital block that will have an individual digit is put into the first digital block combination region respectively or the second digital block combination region makes up; The digital block that will have symbol then is put into the sign field, and after calculating, the digital block that will have individual digit again is put into total demonstration district and makes up.
The utility model is simple in structure, and is easy to use, in the primary school math teaching process, can make things convenient for deaf and dumb student's memorizing in images with integrating theory with practice, and effectively improved students'interest in learning, alleviated the work difficulty of teaching.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
Among the figure: the 1-frame; 2-digital block storage area; 3-first longitudinal baffle; The 4-sign field; The 5-second digital block combination region; 6-second longitudinal baffle; The 7-lateral partitions; 8-total demonstration district; The 9-first digital block combination region; The 10-digital block.
Embodiment
Embodiment, as shown in the figure, a kind of mathematics plus-minus method demonstration board that is used for school for deaf-mutes's teaching comprises the base plate of processing with magnetic material, has frame 1 around the said base plate, said base plate is provided with first longitudinal baffle 3 and second longitudinal baffle 6; The two ends of the two ends of first longitudinal baffle 3 and second longitudinal baffle 6 are connected with frame 1 respectively; The two ends of first longitudinal baffle 3 and second longitudinal baffle 6 are partitioned into digital block storage area 2, digital block combination region and sign field 4 with base plate, are placed with the digital block of processing with magnetic material 10 that several are marked with individual digit or symbol in the digital block storage area 2.
The position that is positioned at the digital block combination region on the base plate is provided with twice lateral partitions 7; One end of lateral partitions 7 is connected with first longitudinal baffle 3, the other end is connected with second longitudinal baffle 6, and twice lateral partitions 7 is partitioned into the digital block combination region in the first digital block combination region 9, the second digital block combination region 5 and the total demonstration district 8 that is arranged above and below.
During teaching; The digital block 10 that will have an individual digit is put into the first digital block combination region 9 respectively or the second digital block combination region 5 makes up; The digital block 10 that will have symbol then is put into sign field 4; After calculating, the digital block 10 that will have individual digit again is put into total demonstration district 8 and makes up.
