Abstract

The utility model discloses an abacus for enlightening elementary intelligence of young children, which breaks the traditional structural style of an abacus. The utility model is characterized in that the lower part of the surface of the abacus is provided with an iron plate, a liner plate and a back cover in turn, and the upper part thereof is provided with unit's place moving abacus beads, ten's place moving abacus beads and hundred's place moving abacus beads. The unit's, ten's and hundred's places which are printed on the surface of the abacus, and fixed moving abacus beads are used as marks. When calculation, the moving abacus beads are slid up and down to carry out calculation. The utility model is particularly suitable for preschool children and one to two-year students to use so as to reach numerical elementary education.

Description

The child opens the intelligence abacus

The child that the utility model relates to opens the intelligence abacus, belongs to computational tool.

Existing abacus is provided with crossbeam in frame, and vertical array has a plurality of vertical beams, string has abacus bead on the vertical beam, two abacus beads of crossbeam top, and each represents 5, each represents 1 abacus bead under the crossbeam, when specifically calculating, sets arbitrarily and counts from vertical beam that to be arranged in order be individual position, ten, hundred ... but for the child who begins to learn calculating, be difficult to identification, reading is not directly perceived, and abacus bead is easy to be struck, be not suitable for the child and do and open the intelligence computational tool, and carry inconvenience.

The purpose of this utility model is intended to improve above-mentioned deficiency, provides a kind of calculating fast, got rid of to gather the intermediary that slender acanthopanax, the fifth day of the first lunar month subtract and convert, and directly outstanding decimal system counting, reading is directly perceived, and abacus bead is difficult for arbitrarily stirring, and is easy to carry, is fit to the initiation abacus that the child uses.

In order to achieve the above object, the utility model is to realize like this, it has abacus card 1, be printed on side by side successively on the abacus card 1, ten, hundred, corresponding below vertically respectively is arranged as ten fixedly beads, has 0 on individual, ten, hundred left sides, each fixedly bead left side correspondence be printed on 1～10, be characterized in below abacus card 1, being provided with 1 layer of iron plate 2, liner plate 3, back cover 4 successively, be provided with the movable bead of the movable bead in position 5, ten 6, hundred movable beads 7 above it.

The utility model is simple in structure, novel, only utilize three movable beads to move up and down, reach the calculating purpose, it can help the child to learn the number number quickly, recognize number, 10 with interior plus-minus, the formation of 10 system numbers, add with carry, giving up the throne subtracts, calculates with interior plus-minus until 1000, and the utility model is specially adapted in the kindergarten, the top class in a kindergarten and primary school one, sophomore use.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A cut-open view of Fig. 1;

Fig. 3 is the A portion structure for amplifying synoptic diagram of Fig. 2;

Fig. 4 is the broken section structural representation of movable bead.

The explanation of accompanying drawing drawing:

1 abacus card, 2 iron plates, 3 liner plates, 4 back covers, 5 movable beads in position, 60 movable beads, 700 movable beads, 8 movable bead shells, 9 magnets.

In order to understand better and to implement, it is as follows with the accompanying drawing to be that embodiment further specifies below:

Abacus card 1 can adopt the flexible plastic skin, be printed to the represented pattern of Fig. 1 thereon, fixedly bead can be printed to the ball type, griggles or the like, for more directly perceived, fixedly bead on ten than on the position more greatly, on ten of the ratios on hundred more greatly, thick horizontal black line is represented the crossbeam on the abacus; Iron plate 1 can be adopted sheet iron, and liner plate 3 can adopt duroplasts, and back cover 4 flexible plastic skin is docile and obedient abacus card 1 iron plate 2, liner plate 3, back cover 4 preface and is set, and being bonded together with hot-gluing machine at last gets final product; Individual, ten, hundred

movable beads

5,6,7 are a circle, be made up of with magnet 9 a movable bead shell 8, movable bead shell 8 adopts duroplasts to make a circle, and a spill is established in the centre, inlay magnet 9 in spill, movable bead can be inhaled on abacus card 1. and movable bead is used interchangeably.

Concrete operations are as follows: will, ten, hundred

movable beads

5,6,7 are placed on respectively, in ten, hundred the grids on, begin to inspire the child to calculate 1000 with interior plus-minus method.

1, addition.Does for example: how expressing you on abacus card 1 have 6 griggles? operation: pick up a movable bead 5 in position, begin to count by the fixedly bead in the 1st grid from the top down and count to 6 from 1, the movable bead in individual position is parked in the 6th grid, give you 3 griggles again, do you always have several griggles? operation: pick up a movable bead of position and down count, add 1, add 2 from the 6th grid, add 3, the movable bead 5 in individual position is parked in is marking in 9 the grid.

2, subtraction.For example: you have 6 griggles, eat up 2, is it also surplus several? an operation: pick up the movable bead in position and slide into 6 from 1, make progress several 1,2 since 6 position again, at last the movable bead 5 in individual position is parked in the grid of marking numeral 4 also surplus 4 of expressions.

3, carry addition.For example: you have had 6 griggles, does giving you 60 more always have several? operation: pick up a movable bead 5 in position and slide into downwards in the 6th lattice, add 1～4 again, arrive the tenth grid, here ten movable beads 6 are placed in the tenth grid temporarily, hold the movable bead 5 in position in the hand and return in first grid beginning 5 of points downwards again, 6, the movable bead in individual position is parked in second grid.Then with one on ten fixedly bead represent 10 griggles, taking away ten movable beads 6 of that piece of putting temporarily in the last ten grid in position moves on in 1 lattice under ten grids, what represent on the abacus card like this is exactly 12, skilled after, sum up " add 6 go 4 advance 1 ".

4, the subtraction of giving up the throne.For example: you have 12 griggles, eat up 6, also surplus several? operation: ten movable beads 6 are upwards moved lattice (deducting 1), in the tenth grid of individual position, put one piece of movable bead temporarily, this expression is exchanged 10 griggles, deducts 6 then in the middle of these 10, with remaining 4 with original on 2 additions, the movable bead 5 in individual position is put in the 6th grid also remaining 6 of expressions.After skilled, sum up: " subtract 6 move back 1 add 4 ".

Whole making and manipulating finishes.
