Abstract
The utility model relates to a mental abacus calculation teaching tool used for teaching. The mental abacus calculation teaching tool includes at least 1 to 10 rows (1) which are perpendicular to the ground and are arranged in parallel, and five abacus beads (3, 4) arranged up and down. Each row (1) adopts five abacus beads (3, 4) which are in different shades and can move up and down and vertically to the ground. The five abacus beads are divided into an upper abacus bead (4) and four lower abacus beads (3). A spacing device (2) is arranged between the upper abacus bead and the lower abacus beads. Because the abacus beads are different in shade, a learner can form a colored abacus bead image in brain, and through the learning interest cultivation, the learner can grasp the mental abacus calculation easily, and the calculation accuracy can also be improved obviously.
Description
Technical field
The utility model relates to a kind of teaching aid of imparting knowledge to students and using, and particularly relates to a kind of abacus mental calculation teaching aid of imparting knowledge to students and using of being used to.
Background technology
Abacus is a kind of traditional calculating instrument, because it is easy to carry, also has a lot of countries and regions using abacus as computational tool in the world in today that computing machine is popularized.On the abacus basis, develop the abacus mental calculation that also by a lot of countries in the world as the methods of exploitation children's intelligences, receive everybody like and approve.But when adopting abacus mental calculation to carry out numerical evaluation, require student's brain that clear, pearl picture is accurately arranged.But often can find that in field research the student uses abacus mental calculation to calculate possibly to occur answer to differ from 1 or differ from 5 problem.The reason that causes miscount is that brain is videoed fuzzy when calculating owing to the student.
In addition, although the abacus of band look pearl is arranged at present, its effect is to be used for the location, and the note site on the abacus also is to be used for locating, and helps not quite improving to calculate accurately.
Summary of the invention
The utility model technical matters to be solved provides a kind of abacus mental calculation teaching aid that is used to impart knowledge to students and uses, and strengthens digital brain reflection, is study mental arithmetic place mat.
The utility model solves the technical scheme that its technical matters adopted: a kind of abacus mental calculation teaching aid of imparting knowledge to students and using of being used to is provided; Comprise the shelves of 1-10 at least that are parallel to each other perpendicular to the ground and 5 beads up and down; Described every grade is adopted color that the depth is arranged; Five beads that the ability vertical ground moves up and down wherein are divided into 1 and go up bead and 4 following beads, and stop means is arranged between the bead up and down.
It is position retainings that described 1-10 shelves are divided into 1 shelves perpendicular to the ground, and 2 shelves perpendicular to the ground from left to right are to pick up a position retaining and a position retaining, and 3 shelves perpendicular to the ground from left to right are one hundred retainings, pick up the position retaining and individual position keeps off, and the like.
Described five beads color from top to bottom are light color/dark color/dark color/light color/light color, dark color/light color/light color/dark color/dark color, light color/dark color/dark color/dark color/dark color or dark color/light color/light color/light color/light color successively.
When described position was blocked bead and moved down into stop means, expression numeral " 5 " was picked up when the position retaining moves down into stop means and is represented numeral " 50 ", representes numeral " 500 " when one hundred retaining moves down into stop means, and the like.
When 4 following beads of described position retaining moved on to stop means on respectively, expression numeral " 1-4 " was when picking up the position retaining bead moving on to stop means on respectively down; Expression numeral " 10-40 "; When bead moves on to stop means on respectively under one hundred retaining, expression numeral " 100-400 ", and the like.
A described position shelves perpendicular to the ground are boundary with the stop means, and last bead moves down and following bead moves 3 simultaneously, the bead permutation table registration word " 8 " of composition.
Described the picking up from left to right of being parallel to each other perpendicular to the ground, individual position shelves are boundary with the stop means, and last bead moves down 1 and following bead simultaneously and moves 3 simultaneously, the bead permutation table registration word " 88 " of composition.
Described perpendicular to the ground be parallel to each other from left to right one hundred, pick up, individual position shelves, be boundary with the stop means, last bead moves down 1 and following bead simultaneously and moves 3 simultaneously, the bead permutation table registration word " 888 " of composition.
The utility model is the basis with the abacus mental calculation, make the operating process of calculating on an abacus fully " internalization ", relies on Calculation Method such as this " the psychological abacus " of " internalization " adds in brain, subtracts, multiplication and division.Make learner's clear, abacus accurately of in brain, videoing out, carry out numerical evaluation through mental arithmetic then.According to said method; Among Fig. 1 the numeral that will express then be 258 form coloured pearl picture in learner's brain because the bead of different colours makes, thus for study mental arithmetic place mat when abacus mental calculation; Not only the brain reflection is able to simplify; Promptly replace the abacus reflection with look pearl reflection, and with the numeration of look pearl can also accurately judge bead in the brain reflection the position and and number, make abacus mental calculation calculating more accurate.The quantity that only needs in addition to increase shelves just can be represented bigger numeral, as to adopt four shelves be that the digital scope that the kilobit shelves are represented is exactly " 0～9999 ", adopt five shelves be myriabit to keep off the digital scope of representing be exactly " 0～99999 ", by that analogy.
Beneficial effect
The utility model makes to form coloured pearl picture in learner's brain because bead uses various colors, through the cultivation of learning interest, can easily grasp mental arithmetic, obviously improves the accuracy of calculating.
