Description
Technical field
The utility model category technique of bead calculation field more particularly to a kind of selfish calculations suitable for rudimentary maths initiation education.
Background technique
Currently, well known abacus is classical technique of bead calculation.Its shape is rectangular, and periphery is frame, is vertically arranged with shelves, above and below,
Series connection bead.Generally from nine grades to 15 grade, horizontal with beam in shelves, upper pearl is 2, and lower pearl is 5, dials pearl and calculates, becomes a kind of meter
The purpose that counts tool.But abacus is not suitable for children and initially learns to recognize to figure art since registration function is insufficient, it is not general
All over for rudimentary maths initiation education.And other learn number puzzle, the general simple mode combined using pearl with numerical chracter, function
It is single, lack system arithmetic function.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of selfish calculations suitable for rudimentary maths initiation education, it will
These basic natural numerical symbols are matched with rechoning by the abacus integration, and the meaning of these basic natural numerical symbols is made to pass through bead registration method
Clear expression, and include wherein, there is complete registration and calculation function by abacus.
The utility model is achieved through the following technical solutions：
A kind of selfish calculations suitable for rudimentary maths initiation education include a rectangular frame, in rectangular frame, are equipped with 5 and erect
Shelves, in the middle part of the vertical file, are vertically equipped with two parallel crossbeams, are upper beam and underbeam；Above the upper beam, 5 perpendicular
0,1,2,3,4 bead is configured in order on shelves from left to right；Among the upper beam and underbeam, 1 is each equipped in 5 vertical files
Bead；Below the underbeam, 5 beads are each equipped in 5 vertical files.
Preferably, corresponding to 5 vertical files, on the upper side frame of rectangular frame, it is configured in order 1,2,3,4,5 from left to right
This five natural numerical symbols on the lower frame of rectangular frame, are configured in order 6,7,8,9,10 this five natural numbers from left to right
Symbol is answered for matching with each shelves bead.
The invention also discloses a kind of selfish calculations suitable for rudimentary maths initiation education, the selfish calculations are by above-mentioned
Selfish calculations laterally side by side and remove ten to be spliced after the left frame of left side selfish calculations, the left frame of the right selfish calculations
Shelves selfish calculations on the upper side frame of the rectangular frame of the selfish calculations at described ten grades, correspond to 10 vertical files, configure in order from left to right
There are 1,2,3,4,5,6,7,8,9,10 this ten natural numerical symbols, for corresponding with each shelves bead.
The utility model has the beneficial effects that：Its clever structure enhances the registration function of abacus, and structure is upright simple,
With complete registration and calculation function, is conducive to culture children and learns to recognize to figure art, improve the interest to abacus, promote
Rechoning by the abacus culture.
Detailed description of the invention
The utility model is described in detail by following specific embodiments and drawings for ease of explanation,.
Fig. 1 is the structural schematic diagram of selfish calculations；
Fig. 2 is the structural schematic diagram of ten grades of selfish calculations；
1. upper side frames in figure, 2. left frames, 3. lower frames, 4. left frames, 5. vertical files, 6. upper beams, 7. underbeams, 8. beads,
9. natural numerical symbol.
Specific embodiment
As shown in Figure 1, a kind of selfish calculations suitable for rudimentary maths initiation education, include a rectangular frame, rectangular frame includes
Upper side frame 1, left frame 2, lower frame 3, left frame 4 are equipped with 5 vertical files 5 in rectangular frame, at 5 middle part of vertical file, hang down
Direct puncture is equipped with two parallel crossbeams, is upper beam 6 and underbeam 7；Above the upper beam 6, in 5 vertical files 5 from left to right successively
Configured with 0,1,2,3,4 bead 8；Among the upper beam 6 and underbeam 7,1 bead 8 is each equipped in 5 vertical files 5；Institute
7 lower section of underbeam is stated, is each equipped with 5 beads 8 in 5 vertical files 5.
Corresponding to 5 vertical files 5, on the upper side frame 1 of rectangular frame, it is configured in order 1,2,3,4,5 this five from left to right
Natural numerical symbol 9 on the lower frame 3 of rectangular frame, is configured in order 6,7,8,9,10 this five natural numerical symbols from left to right
9, it is answered for matching with each shelves bead.
As shown in Fig. 2, a kind of selfish calculations suitable for rudimentary maths initiation education, the selfish calculations are horizontal by above-mentioned selfish calculations
Being spliced after the left frame 4 of left side selfish calculations, the left frame 2 of the right selfish calculations to arranged side by side and removal is ten grades of small calculations
Disk on the upper side frame of the rectangular frame of the selfish calculations at described ten grades, corresponds to 10 vertical files, be configured in order 1 from left to right, 2,
3,4,5,6,7,8,9,10 this ten natural numerical symbols, for corresponding with each shelves bead.
The utility model clever structure, enhances the registration function of abacus, and structure is upright simple, have complete registration and
Calculation function is conducive to culture children and learns to recognize to figure art, improve the interest to abacus, promotes rechoning by the abacus culture.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
Therefore, the protection scope of the utility model should be determined by the scope of protection defined in the claims.
