Abstract
The utility model proposes a kind of imitative ten pearl mathematical operations boxes of hand, including operating learning aid ontology, the operation learning aid ontology (1) has preset length, and operation learning aid ontology (1) front has the first operating space (2), and the back side is provided with the second operating space (5).The purpose of this utility model is to propose a kind of ten pearl mathematical operations box of imitative hand, the advantage of Chinese abacus and the advantage of west Meng Shi teaching aid are combined, find mathematics derived from hand simultaneously, it imitates in manpower by mathematical regression nature, quantity is perceived as children, realize mathematics, divide operating unit from less to more, by delocalization to positioning, understand that mathematical operation is held in support to advanced progressively reach by rudimentary, it determines eager to learn handy without keeping mouth firmly in mind, uses one's hands and brains and develop child's intellectual potential, can be used as the auxiliary tool of children for learning mathematics.
Description
Technical field
The utility model relates to a kind of calculating instrument, feature is related to a kind of ten pearl mathematical operations box of imitative hand.
Background technique
Abacus is a kind of main calculating instrument of Chinese tradition, including frame, beam, shelves, pearl composition.This abacus Liang Shangyi
Pearl represents 5, Liang Xiayi pearl and represents 1, does not require nothing more than user and keeps pithy formula firmly in mind during using abacus, while must be to rechoning by the abacus
Rule it is very familiar just can be used, for children learn get up to have any problem.
West Meng Shi learning aid gives many mathematics learning aids of child, allows child's hands-on, is suitble to the cognitive law of children, letter
It is single easy to learn, but it is efficiently rapid without Chinese abacus to calculate effect.
Utility model content
In order to solve the defects of prior art with deficiency, the utility model embodiment provide a kind of structure more rationally and
It can be used without keeping abacus rhymes firmly in mind i.e., can be used as the auxiliary tool of child's learning mathematics.The technical solution is as follows:
The utility model proposes a kind of imitative ten pearl mathematical operations boxes of hand, including operation learning aid ontology, the operation to learn
Having ontology (1) has preset length, and with the first operating space (2), the back side is provided with the in the operation learning aid ontology (1) front
Two operating spaces (5)；
First behaviour area (2) is provided with a pearl bar (3), is socketed with ten pearls (4) on the pearl bar (3), on the pearl bar (3)
Color positioned at five pearls of upside is not identical as the color for five pearls for being located at downside；
Second operating space (5) is respectively sleeved on ten pearls (7) on each pearl bar (6), often at least provided with two pearl bars (6)
(6) it is not identical as the color for five pearls for being located at downside to be located at the colors of five pearls of upside on a pearl bar.
As above-mentioned technical proposal preferential, operation learning aid ontology side is provided with equation viewing area (8), described etc.
Formula viewing area can adjust change number, oeprator and relational symbol as needed.
As above-mentioned technical proposal preferential, each operating space is provided with one shutter, and the shutter being capable of basis
Need to block its operating space.
As above-mentioned technical proposal preferential, a pearl bar of each operating space is provided with one shutter (9), the screening
Baffle can block the pearl on a pearl bar and the pearl bar for its operating space as needed.
The purpose of this utility model is to propose a kind of ten pearl mathematical operations box of imitative hand, and the advantage of Chinese abacus and west are covered
The advantage of family name's teaching aid combines, while finding mathematics derived from hand, imitates in manpower by mathematical regression naturally, perceiving number as children
Amount, realizes mathematics, divides operating unit from less to more, by delocalization to positioning, understands that number is held in support to advanced progressively reach by rudimentary
Student movement is calculated, and is determined eager to learn handy without keeping mouth firmly in mind, is used one's hands and brains and develop child's intellectual potential, can be used as the auxiliary of children for learning mathematics
Assistant engineer's tool.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings.

Fig. 2 is that the ten pearl mathematical operations box back side of imitative hand provided in the present embodiment is the structural schematic diagram of 2 pearl bars；
Fig. 3 is that the ten pearl mathematical operations box back side of imitative hand provided in the present embodiment is the structural schematic diagram of 3 pearl bars；
Fig. 4 be 11, the back side of the pearl mathematical operations box pearl bar of imitative hand provided in the present embodiment be blocked plate block after knot
Structure schematic diagram.
Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
The utility model proposes a kind of imitative ten pearl mathematical operations box of hand, including operation learning aid ontology, the operation learning aid sheets
External shape, which can according to need, is arranged to different shape, such as apple, elephant etc., and the operation learning aid ontology 1 has preset length
Degree, 1 front of operation learning aid ontology have first operating space 2, and the back side is provided with the second operating space 5；
First behaviour area 2 is provided with a pearl bar 3, and ten pearls 4 are socketed on the pearl bar 3, are located at upside on the pearl bar 3
The color of five pearls is not identical as the color for five pearls for being located at downside；
Second operating space 5 is respectively sleeved on ten pearls 7 at least provided with two pearl bars 6 on each pearl bar 6,6 on each pearl bar
Color positioned at five pearls of upside is not identical as the color for five pearls for being located at downside.
Operation learning aid ontology side is provided with equation viewing area 8, and the equation viewing area can adjust as needed
