The addition-subtraction operation demonstrator for deaf-mute children comprises a board body, wherein five frame bodies are arranged above the board body from the left to the right in sequence; the five frame body consists of a first digital block storage region, an addition-subtraction sign block storage region, a second digital block storage region, an equal sign block storage region and a third digital block storage region, wherein ten single-digit magnetic blocks of 0-9 are stored in each of the first digital block storage region, the second digital block storage region and the third digital block storage region; an addition magnetic block and a subtraction magnetic block are stored in the addition-subtraction sign storage region; an equal signal magnetic block is stored in the equal sign block storage region; and five frame bodies including the first digital block storage region, the addition-subtraction sign block storage region, the second digital block storage region, the equal sign block storage region and the third digital block storage region from the left to the right in sequence are arranged below the board body. The addition-subtraction operation demonstrator for deaf-mute children has the beneficial effects that firstly, the structure is simple; secondly, the addition-subtraction operation demonstrator is convenient for the deaf-mute children to understand the addition-subtraction operation, so that the teaching effect is improved; and thirdly, the addition-subtraction operation demonstrator is convenient for hanging.
Description
Technical field
The utility model relates to a kind of deaf-mute child and uses schooling apparatus, and particularly a kind of deaf-mute child uses the signed magnitude arithmetic(al) demonstration device.
Background technology
At present, carry out because deaf-mute child's listening and speaking ability is restricted, thereby using common teaching method in the process of signed magnitude arithmetic(al) teaching in school for deaf-mutes, deaf and dumb student is difficult to understand, so teaching efficiency is not good.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of simple in structure, vivid thereby deaf-mute child that be convenient to deaf and dumb student's rational learning to use the signed magnitude arithmetic(al) demonstration device.
in order to solve the problems of the technologies described above, deaf-mute child of the present utility model uses the signed magnitude arithmetic(al) demonstration device, comprise the plate body of being made by stainless steel material, the top of described plate body is established five frameworks from left to right successively, these five frameworks are respectively the first digital block storage area, plus-minus symbolic blocks storage area, the second digital block storage area, equal sign piece storage area and the 3rd digital block storage area, described the first digital block storage area, the second digital block storage area and the 3rd digital block storage area have all been deposited ten units magnetic patch of 0-9, described plus-minus symbolic blocks storage area has been deposited addition magnetic patch and subtraction magnetic patch, described equal sign piece storage area has been deposited the equal sign magnetic patch, the below of described plate body also is provided with five frameworks from left to right successively, and these five frameworks are respectively the first digital block demonstration district, the demonstration of plus-minus symbolic blocks district, the second digital block demonstration district, equal sign piece demonstration district and the 3rd digital block demonstration district.
For the ease of hanging, deaf-mute child of the present utility model uses the signed magnitude arithmetic(al) demonstration device, and the top of described plate body is provided with a link.
The beneficial effect that the utility model is obtained is: (1) is simple in structure; (2) signed magnitude arithmetic(al) is decomposed into five parts, the numeral of these five parts or symbol leave in respectively in five frameworks, in the time of demonstration, these five parts also are placed on respectively in five frameworks, thereby vivid, be convenient to deaf and dumb student and understand signed magnitude arithmetic(al), improved teaching efficiency; (3) top of plate body is provided with a link, is convenient to hang.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, plate body, the 2, first digital block storage area, 3, plus-minus symbolic blocks storage area, 4, the second digital block storage area 5, equal sign piece storage area, the 6, the 3rd digital block storage area, the 7, the 3rd digital block demonstration is distinguished, 8, equal sign piece demonstration district, the 9, second digital block demonstration district, 10, plus-minus symbolic blocks demonstration district, 11, the first digital block demonstration is distinguished, 12, link, 13, digital magnetic patch, 14, the subtraction magnetic patch, 15, addition magnetic patch, 16, the equal sign magnetic patch.
Embodiment
as shown in Figure 1, deaf-mute child of the present utility model uses the signed magnitude arithmetic(al) demonstration device, comprise the plate body 1 of being made by stainless steel material, the top of described plate body 1 is established five frameworks from left to right successively, these five frameworks are respectively the first digital block storage area 2, plus-minus symbolic blocks storage area 3, the second digital block storage area 4, equal sign piece storage area 5 and the 3rd digital block storage area 6, described the first digital block storage area 2, the second digital block storage area 4 and the 3rd digital block storage area 6 have all been deposited ten digital magnetic patch 13 of 0-9, described plus-minus symbolic blocks storage area 3 has been deposited addition magnetic patch 15 and subtraction magnetic patch 14, described equal sign piece storage area 8 has been deposited equal sign magnetic patch 16, the below of described plate body 1 also is provided with five frameworks from left to right successively, and these five frameworks are respectively the 8 and the 3rd digital block demonstration district 7, the 10, second digital block demonstration district 9, the first digital block demonstration district 11, the demonstration of plus-minus symbolic blocks district, the demonstration of equal sign piece district, the top of described plate body 1 is provided with a link 12.
in the time of concrete the use, the first digital block storage area 2, the second digital block storage area 4 and the 3rd digital block storage area 6 have all been deposited ten digital magnetic patch 13 of 0-9, plus-minus symbolic blocks storage area 3 has been deposited addition magnetic patch 15 and subtraction magnetic patch 14, equal sign piece storage area 8 has been deposited equal sign magnetic patch 16, therefore, the teacher can be according to the actual operation rule, choose respectively the first digital block storage area 2, plus-minus symbolic blocks storage area 3, the second digital block storage area 4, equal sign piece storage area 5 and the 3rd digital block storage area 6 are respectively chosen a digital magnetic patch 13, addition magnetic patch 15 or subtraction magnetic patch 14 and equal sign magnetic patch 16, and put into corresponding the first digital block demonstration and distinguish 11, plus-minus symbolic blocks demonstration district 10, the second digital block demonstration distinguishes 9, the 8 and the 3rd digital block demonstration of equal sign piece demonstration district is distinguished in 7, form a complete addition formula or subtraction formula, thereby vivid, be convenient to deaf and dumb student and understand signed magnitude arithmetic(al).
