Abstract

The utility model discloses a novel calculator for children which is composed of a center beam, cases, beads, etc. Because of different styles, some are provided with bases, some are provided with frames, and the beads of the novel calculator for children are provided with a plurality of forms of arrangements from 0 to 10. The sum of the beads of each case of the two sides of the center beam is equal. The beads can be distinguished, can be compared, and can be combined and divided. The beads can be moved along a single direction, opposed, or multiple directions. The calculator for children is characterized in that the numbers of cases can be added or subtracted according to one as a unit, the calculator for children can be positioned by gears or beads, the calculator for children can be used laterally and vertically, etc. The calculator for children is a playing aid, a learning aid, and a teaching aid. The calculator for children is suitable for the use of the kindergarten children and the first grade and the second grade primary school children. The calculating problem habit of dividing fingers and counting small sticks can be changed, the purposes of developing thinking and improving intelligence can be achieved, and a foundation for learning well-known abacus can be laid.

Description

Calculator for child

The utility model relates to three kinds of novel children counters, includes 5 pearl counters, 10 pearl counters and 20 pearl counters.

In the prior art, children's counter is made up of shelves, framework and pearl, and weak point is: on one side pearl is arranged, the exercise type is restricted; 10 on pearl is one group, and simple set in kind before one group of group proper alignment and the children with ocular is inconsistent; Structure is multi-gear type or stand formula, and use in inconvenient children classroom.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art and three kinds of children's counters are provided.

Technical solution of the present utility model is: central sill 2 and the shelves 3 that are installed with pearl 1 are arranged in the framework 4, and there are placed in the middle and inclined to one side slightly branch in the position of central sill.

Technical solution of the present utility model also comprises: is the boundary with the central sill, pearl is divided into both sides arranges,, increase progressively Yi Bian be Yi Bian taper off, and the both sides equalization that has, each shelves is gone up the pearl number and is equated.Go up the pearl number and be 5 for every grade, can have 6～1 grades.Go up the pearl number and be 10 for every grade, can have 6～1 grades.Go up the pearl number and be 20 for every grade, can have 1～many grades.

Accompanying drawing drawing of the present utility model is described as follows:

Fig. 1 is 5 pearl counter synoptic diagram, and 6 grade of 30 pearl arranged.

Fig. 2 is 5 pearl counter synoptic diagram, and 1 grade of 5 pearl arranged.

Fig. 3 is 10 pearl counter synoptic diagram, and 6 grade of 60 pearl arranged.

Fig. 4 is 20 pearl counter schematic perspective views, and 3 grade of 60 pearl arranged.

Fig. 5 is 20 pearl counter synoptic diagram, and 5 grade of 100 pearl arranged.

The utility model embodiment is described as follows:

Embodiment 1: see shown in Figure 1, be 5 pearl counters, be the stand formula, framework 4 is made up of two supports on the base 5, and central sill 2 is positioned in the middle of two supports, the pearl number on the left side is from 5 to 0 arrangements that taper off from top to bottom, have 15 pearls, the pearl number from 0 to 5 on the right is and increases progressively arrangement, has 15 pearls, go up the pearl number and all be 5 for every grade, always have 6 grade of 30 pearl.

Embodiment 2: seeing shown in Figure 2ly, is 5 pearl counters, wears 3 and 2 pearls 1 respectively on 1 grade 3 on central sill 2 both sides, also can occur with the form of two grade of 10 pearl, and its framework 4 forms can be changeable, can be fitted on children's dolly or on other children's article.

Embodiment 3: seeing shown in Figure 3ly, is 10 pearl counters, can keep flat use.In the framework 4 of sealing fixing central sill 2 is arranged, central sill from 5 to 0 arrangements that taper off from top to bottom of the pearl 1 on the shelves 3 on one side have 15 pearls, the pearl of another side from 5 to 10 is and increases progressively arrangement, has 45 pearls, and central sill deflection pearl less on one side, go up the pearl number and all be 10 for every grade, always have 6 grade of 60 pearl.

Embodiment 4: see shown in Figure 4, be 20 pearl counters, promptly every grade has 20 pearls 1, and central sill 2 is positioned in the middle of the framework 4, respectively there are 30 pearls 1 on beam 2 both sides, every grade 3 pearl number and be 20 has the length scale outside always having 3 grade of 60 pearl 1, one long framework, by centimetre for unit not very digital, scale what decide 5 centimetres, 10 centimetres, 15 centimetres with the length of long framework ... the place adds " ▲ " number expression with long vertical line upper end, and all the other are all represented with short vertical line.Scale mark lower ends etc. are neat, with vacating the light face at the bottom of the frame, are used for children and measure, rule, and calculate with the ray line segment.This counter keeps flat use, the pearl 1 of beam 2 both sides as much can about stir.

Embodiment 5: seeing shown in Figure 5ly, is 20 pearl counters, and central sill 2 is positioned in the middle of the framework 4, and respectively there are 50 pearls 1 on the beam both sides, and every grade of pearl number and be 20 always has 5 grade of 100 pearl, assembles nylon hair 7 on the shelves, and there is link 6 on both sides, frame angle, can hang use anyhow.

Among the above embodiment, 5 pearls calculate pearl and 10 pearl counters all display the simple set of neutral gear and number, and the pearl number on beam both sides is had any different and can be compared, and teacher and child can form new set again flexibly according to the teaching of showing.These two kinds of counters can be made into figuratum stand formula of frame face or flatwise, liked by child,, play in playing the middle school for them, progressively accept the notion of number.

Among the above embodiment, 5 grade of 100 pearl calculating appliance of 20 pearls has the function of old-fashioned 100 pearl counters, and new function is arranged again.When the central sill traverse, can locate with shelves, central sill is transferred to a long number up and down respectively, and figure place is identical with the shelves number; When central sill is placed vertically,, can dial and the as many several double figures of shelves number with the pearl location.3 grade of 60 pearl counter of 20 pearls can be practised 10 and 10 components with interior number, and doing not, the plus-minus of fractional bits and fractional bits calculates, can do the inner multiplication pithy formula Preliminary study of dividing of table practises, from the kindergarten or preschool class to primary school's one second grade, all adapt to the teaching material needs, can be the required usefulness of children always; Simple in structure, volume is little, and the student can be used for the classroom by one of staff, eye brain hand mouth and usefulness, and notice is concentrated, and only needs one group of bead is just calculated the result easily, and the student is never again as before with the method arithmetic problem of breaking finger or number spillikin off with the fingers and thumb.

The utility model has the advantages that: pearl from 0 to 10 is arranged in the central sill both sides, 10 set with interior number are all displayed, gear number can increase and decrease, it is multiple that pattern can be made vertical frame type, flatwise, suspension type or pocket etc., can anyhow use, take one as unit, also can locate with pearl with shelves, do type exercise as much as possible with the shelves pearl of trying one's best few, easy to carry, can be used for the classroom, suit children's reality, shorten the training time, improve computing capability, can be with comparalive ease from thinking in images to the abstract thinking transition, and lay the first stone for the later known abacus of study.
