Description

Children mathematical learning equipment

Technical field

The present invention relates to a kind of learning tool, refer to the learning tool of a kind of child's of being applicable to number, knowledge number especially.

Background technology

The teacher and the head of a family adopt card or building blocks to help child's study of numbers or knowledge figure usually at present, but that these cards and building blocks exist mostly is scattered, be inconvenient to put in order and carry, cracky or the shortcoming of losing, in use inconvenient to some extent, and these cards and building blocks can not carry out computing, and usable range is limited.

Abacus is the traditional computational tool of China, is an Ancient Chinese important invention in generation.Use abacus and rechoning by the abacus, except convenience of calculation, also has the effect of thinking skills training, the close fit that needs brain, eye, hand because calculate on an abacus, therefore, though now entered the robot calculator epoch, a lot of schools and the head of a family still can adopt this traditional computational tool to train child's thinking ability.But traditional abacus generally adopts " last two times five ", " last two times four ", " on once five " or " on's once four " bead structure, every bead on the abacus beam represents 5, every bead under the beam represents 1, a same bead of blocking is represented two kinds of numbers in different places, this knows number to the child and has brought certain difficulty, and this abacus calculating pithy formula is many, to on top of need to learn and practise the long time, fast mistake easily takes place in computing, be not suitable for children especially the child impart rudimentary knowledge to beginners study.

For the child, the function of abacus is not to calculate, but a kind of instrument of study of numbers.The multiple abacus that is used to teach child's number is also arranged in the market, for example the patent No. is that 03213281.6 Chinese patent discloses a kind of nine-bead Digital abacus, be on every retaining rod, to be installed with nine beads, and " 0～9 " ten numerals are imprinted on grade rod, full pearl is a neutral gear when falling, on the shelves rod is " 0 ", upwards pulls out several pearls, just occurs several on the shelves rod.The numeral of this nine-bead Digital abacus is to be marked on the retaining rod, exists bead to follow number to separate, and each bead is pressed the problem of a numeral, when treating up to have pulled out bead, the distance of a bead can only be arranged between the upper and lower bead, too little at interval, pull out pearl when not in place, bead can take place block several phenomenons; And the numeral that the child is not easy to discern on the retaining rod is the number of bead above the representative or the number of following bead; And the numeral that is marked on grade rod is less relatively, and the child sees that there is certain difficulty in numeral.

The patent No. is that 200720141123.2 Chinese patent discloses a kind of teaching aid with multiple demo function, is that four outside surfaces at the cube bead are covered with one deck respectively and indicate numeral, represents the point of numeral, the demonstration film of figure and color.When this scheme is used for child's formative education, because numeral is visual all, the notice that can disperse the child, child's mistake easily is the number that this bead is just represented on the bead to be indicated with the number comprehension on the bead, but not is the summation of bead.For example when doing the computing of " 3+5 ", the bead that the child will indicate numeral " 3 " earlier up pulls out, when treating to add " 5 ", the 5th bead is marked with numeral " 5 ", the bead that the child is easy to indicate numeral " 5 " directly up pulls out, rather than pulls out 5 beads and get on, and shows the result of " 8 " again.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, the learning tool of a kind of child's of convenience number, knowledge number, calculating is provided.This learning tool has the pearl of pulling out and sees that number, pearl number are moving with pearl in conjunction with, number, pithy formula characteristics simple, that easily learn.

For achieving the above object, the present invention is achieved by the following technical solutions: children mathematical learning equipment comprises framework, pin and bead.Described pin is 3～20, is vertically installed in the framework, and the pin shape can not rotated with bead and is advisable, and can be prism or cylindroid; Bead has two bottom surfaces, the through hole that is complementary with pin is arranged on the bottom surface, all be installed with nine beads on each pin, on the bottom surface of nine beads of every retaining, indicate " 1～9 " nine numerals successively, when all falling, bead is " 0 ", we cannot see the numeral on the bead, upwards pull out several beads, and just occurring that the bead bottom surface is relative is digital several.In order to read conveniently, bead bottom surface and pin form angle a, and angle a is between 90～150 degree; In order further to be fit to people's reading habit, the angle a that bead bottom surface and pin form is between 120～135 degree; And the upper and lower inboard of framework is parallel with two faces of bead.

For convenient reading, digital corresponding position is marked with digital " 0 " on upper side frame inboard and the bead.

For the ease of distinguishing the bead number, the bead in the centre of nine beads of every grade can be heterochromatic pearl.

Can on framework, establish the numerical digit board, to make things convenient for the understanding of child to numerical digit.

The bead of each grade is that the different color or the bead of three shelves are a color, is used to represent different positions.

Beneficial effect:

With the patent No. is that 03213281.6 Chinese patent is compared, the present invention is hidden in numeral " 1～9 " bottom surface of bead successively, when all falling, bead is " 0 ", we cannot see the numeral on the bead, upwards pull out several pearls, just occurring that the bead bottom surface is relative is digital several, have the pearl of pulling out and see number, number is with the moving effect of pearl, and a numeral is all arranged on each bead, and which bead what easy understanding of child and discriminating digit were represented is, does not have the situation of bead retaining number, and the numeral that is marked on the bead bottom surface is obvious relatively, makes things convenient for the child to see number.

With the patent No. is that 200720141123.2 Chinese patent is compared, numeral of the present invention is hidden in the bottom surface of bead, the child only just can see numeral after dialling pearl, visual numeral is just only represented single bead, the child understands the independent representative of each bead " 1 " easily, be convenient to the child and form, be suitable for the formation of the notion of child's logarithm, the understanding of numeral to bead number and the digital notion that combines; For example when doing the computing of " 3+5 ", child's several 3 beads earlier pulls out up, numeral " 3 " just appears in the bead bottom surface, the child can be by the bead bottom surface digital core to oneself number to mistake, because do not have numeral on the following bead, the child will dial up by several 5 beads, result " 8 " just directly is presented on last that bead, the child can significantly feel, every representative " 1 " that bead is independent, when pulling out up with other beads together just expression and above the summation of bead, just be marked on the numeral of bead bottom surface.

Because numeral is the bottom surface that is hidden in bead, have only by up pulling out the pearl This move and just can see the numeral of bead bottom surface, a process of finding is arranged, be and so on to feel below giving that the child who begins to learn numeral is a kind of and wondering actually, increased child's learning interest.Nine beads are arranged on the every pin, satisfy metric requirement.And bead bottom surface and pin form the angle a between 90～150 degree, adapt with people's reading habit, have made things convenient for the child to see number.Also can carry out simple calculations, as long as the child knows " one go nine advance one ", " two go eight advance one ", " three go seven advance one ", " four go six advance one ", " five go five advance one ", " six go four advance one ", " seven go three advance one ", " eight go two advance one ", the addition pithy formula of " nine go one advance one " and " one move back one also nine ", " two move back one goes back eight ", " three move back one goes back seven ", " four move back one goes back six ", " five move back one goes back five ", " six move back one goes back four ", " seven move back one goes back three ", " eight move back one goes back two ", the subtraction pithy formula of " nine move back once going back one " can be calculated, and it is simple to have pithy formula, the characteristics of Yi Xue.
