Abstract
The utility model discloses a magnetic multifunctional dynamic model for common digits in elementary school mathematics, which comprises a base 12, flat slabs 8-11, a half flat slab 6, strips 1-4, and ten identical small cubes 5, wherein the strips 1-4 present a cuiboid shape, the bottom of each strip 1-4 is inlaid with two magnets 16, the haft flat slab 6 presents a cuiboid shape with the bottom bonded with an iron sheet 7, a cylindrical shaft embossment 14 is arranged at the middle of each flat slab 8-11 respectively, a cylindrical groove 15 is arranged at the middle of the top of each flat slab 9-11 respectively, and the flat slab 8-11 are connected with the base 12 via the shaft embossments and the grooves. By aids of the arrangements, the utility model is easy for students and teachers to operation, rich in dynamic and multiple in functions.
Description
Technical field
The utility model relates to a kind of teaching aid, the dynamic model of the magnetic, multi-functional of digit commonly used in definite a kind of primary school mathematics of saying so.
Background technology
In primary school math teaching, in the time of study " one ", " ten ", " hundred ", " thousand " these digits, all to help the student and understand its meaning by some mock-ups.Wherein writing by teaching research chamber, Shandong Province, by Qingdao publishing house January in 2005 the 1st edition, in the primary school mathematics second grade volume two textbook of in January, 2008 the 5th printing, in the time of study " thousand " this digit, be the square that adopted the line of drawing squares as model, visible the 12nd page of the first half of this book.In order to point out the relation between digit " hundred " and " thousand ", design is merged into the model of 1 " thousand " in the textbook with the model of 10 " hundred ".And how the model of synthetic 1 thousand of this model of 10 hundred, current teaching materials does not provide scheme.And will really allow the student be combined into 1 thousand to 10 hundred at last in this way in field research is very to bother, be not easy to operation, even we have tried every possible means to solve the problem of bad operation, this also can only be used for the teaching of " hundred " and " thousand " these two digits, and function ratio is more single.This problem is taught in the teaching material of version and the teaching aid the people and is not solved too.In the teaching aid learning aid of its displaying, the model of square is also arranged, but the form of the model of these squares all is changeless.So under the current situation of implementing new curriculum energetically, can the innovative design a kind of digit's mock-up that is easy to teachers and students' operation, rich dynamic, diverse in function becomes requirement and the call of epoch to us.
Summary of the invention
The purpose of this utility model is that the dynamic model of magnetic, multi-functional of digit is provided always in the primary school mathematics that provides a kind of teachers and students of being easy to operate.
For reaching above purpose, the utility model comprises base 12, dull and stereotyped 8 to 11, half dull and stereotyped 6, rectangular 1 to 4 and ten identical blockage 5, rectangular 1 to 4 is rectangular shape, be provided with the cut-off rule that its average mark is slit into ten blockages for every rectangular 1 to 4, all be embedded with two blocks of magnet 16 every rectangular 1 to 4 bottom, ten blockages 5 are respectively the square shape, be embedded with magnet 17 in the bottom of each blockage 5, half dull and stereotyped 6 is a rectangular shape, its bottom is stained with an iron plate 7, the area of described iron plate 7 is twices of half dull and stereotyped 6 base areas, half dull and stereotyped 6 is provided with the cut-off rule that expression is divided into half flat board 6 50 blockages, dull and stereotyped 8 to 11 are a rectangular shape, on every flat board 8 to 11, be provided with the cut-off rule that flat board is divided into 100 same blockages, middle part, bottom dull and stereotyped 8 to 11 is provided with a columniform crown of roll 14, be provided with a columniform groove 15 at dull and stereotyped 9 to 11 crown center positions, top dull and stereotyped 8 is embedded with four blocks of magnet 13, base 12 is a rectangular shape, it is provided with the cut-off rule that base 12 is divided into 500 same blockages, crown center position at base 12 also is provided with a cylinder shape groove, rectangular 1 to 4 and ten blockage 5 all is adsorbed on the iron plate 7, with half dull and stereotyped 6 formations, one monoblock flat board, iron plate 7 is adsorbed on dull and stereotyped 8 by the magnet 13 on dull and stereotyped 8, and flat board 8 to 11 and base 12 all link together by crown of roll and groove.
By above setting, the utility model assembly is the model of a square, and its overall appearance effect is that 6 faces in a front, back, left, right, up, down all are decorated with 10 squares of taking advantage of 10 little lattice, and the size of square is changeable.The characteristics of this model are to have magnetic, rich innervation, diverse in function, easy operating.This model has been integrated into a plurality of models of digit " " commonly used in the primary school math teaching, " ten ", " hundred ", " thousand " in the middle of this part model according to the mentality of designing of a kind of detachable, combination, rotation, and its design mainly relies on each part shape, size, quantity and stamps ruling and realize on part.This method for designing makes the demo function of this model increase greatly.Its most of part can split and make up, and the realization of this function mainly is that the technology by two aspects realizes: the one, thus on part, embed magnet and design lastblock iron plate attracts each other them; The 2nd, designing crown of roll and groove on the part, they can be spliced and split mutually.Its numerous parts can be taken off arbitrarily, be stained with like this, can also utilize the effect of crown of roll and groove to rotate arbitrarily.Comprised a plurality of digits " one's " model, the model of " ten ", the model of " hundred " in this big square, all combining is exactly the model of a digit " thousand ".Both can be used for the teaching of digit, can be used for the teaching of calculating aspect again, also can be used for the teaching of volume unit aspect.
