Abstract

The utility model relates to a tool for children to learn elementary arithmetic operation with interest by rolling drums. The toll includes a first rotating disc, a second rotating disc, a third rotating disc, a fourth rotating disc, a fifth rotating disc, a sixth rotating disc, a central shaft, a demonstration frame, numbers and operational symbols, and is characterized in that the first rotating disc, the second rotating disc, the third rotating disc, the fourth rotating disc, the fifth rotating disc and the sixth rotating disc are sequentially strung to the central shaft, the demonstration frame is disposed around the rotating discs, two ends of the demonstration frame are riveted to the central shaft, and the numbers and the operational symbols are printed on the rotating discs. The tool allows children to learn the elementary arithmetic operation quickly, and can achieve the effect of mind exercise and practical ability for children.

Description

A kind of child calculates rotating cylinder

Technical field

The utility model relates to a kind of child of allowing learns basic algorithm calculations interestingly by the rotating disk on the rotating cylinder that rolls instrument.

Background technology

At present, the instrument of known algorithm calculations is abacus and counter, and what the child used is a kind of simple and easy abacus, and with the pearl algebraic manipulation, the child cries out in the mouth to draw and sees that numeral but do not recognize after a period of time, and the more inconvenient use of the child of counter ignorant; Magic square when the child plays can be developed child's intelligence, but is not that each child can both use, and because magic square is that foursquare being easy to broken by the child.

Summary of the invention

In order to overcome the deficiency that simple and easy abacus that existing child uses can not display digit, the utility model provides a kind of child to calculate rotating cylinder, and this calculating rotating cylinder can make the basic algorithm calculations of the very fast association of child, and can play the ability that the child beats one's brains and starts.

The technical scheme that its technical matters that solves the utility model adopts is: will calculate rotating cylinder be designed at least six onesize rotating disks side by side string on a central shaft, form, arabic numeral and a space of stamping 0-9 all around in turn from left first rotating disk, stamp in turn around second rotating disk+,-, *, the compute sign of ÷ and several spaces, stamp arabic numeral and a space of 0-9 around the 3rd rotating disk in turn, stamp in turn around the 4th rotating disk 〉,＜,=compute sign and several spaces, stamp arabic numeral and a space of 0-9 around the 5th rotating disk in turn, stamp arabic numeral and a space of 0-9 around the 6th rotating disk in turn, with the demonstration frame that calculates the suitable intermediate void of rotating cylinder length, two of demonstration frame is fixed on central shaft at the arc of outer periphery that calculates rotating cylinder.During use, teacher goes out together simple algorithm calculations topic, the promptly rotatable rotating disk that calculates on the rotating cylinder of child, exercise question and result are arranged in the cavity of demonstration frame by numeral on each rotating disk and compute sign, reach and make the basic algorithm calculations of the very fast association of child, and can play that the child beats one's brains and the effect of the ability of starting.

At least six compositions of described rotating disk are established a space at least around each rotating disk.

Numeral on described each rotating disk and compute sign are uniform character.

Described demonstration frame calculates the rotating cylinder periphery for being close to, and middle cavity is long with to calculate rotating cylinder identical, and width is that the height of the numerical character of rotating disk on all around is identical.

The beneficial effects of the utility model are: this calculating rotating cylinder can make the basic algorithm calculations of the very fast association of child, and can play that the child beats one's brains and the effect of the ability of starting.Since simple in structure, easy to use, be worthy to be popularized.
