Description

A kind of child Qi Zhi abacus

Affiliated technical field:

The utility model relates to the computational tool technical field, is specifically related to a kind of child Qi Zhi abacus.

Background technology:

Rechoning by the abacus is we ancestors' the fifth-largest invention, is the rarity in Chinese nation's excellent traditional culture.In recent ten years, the abacus mental calculation that on the rechoning by the abacus basis, grows up, in the whole nation so world many countries development swift and violent.The study abacus mental calculation can strengthen mentality, in the teaching process of abacus mental calculation, children's hand, eye, ear, matching coordinative mouthful not only, and about also alternately used of the thinking in images of two and half brains and abstract thinking, be very beneficial for the exploitation of student's intelligence.But the problem that exists in the present abacus mental calculation teaching reflects existing abstract because of structure exists, the not intelligible problem of abacus, and imbody is: 1, the decorative pearl on top of an official cap is with a top five, and the child understands difficulty, and increase is crossed the threshold difficulty and lost learning interest; 2, layout dullness, pattern is simple, causes the beginner to be difficult for understanding relation between the height of gear and numerical digit; 3, anchor point is easily obscured, and causes computing to make mistakes easily.These problems have a strong impact on the enthusiasm that the child learns abacus mental calculation, thereby influence the popularization of abacus mental calculation.

Summary of the invention:

The utility model will provide a kind of child Qi Zhi abacus, to overcome the abstract and not intelligible problem that prior art exists.

For overcoming the problem that prior art exists, the technical solution of the utility model is: a kind of child Qi Zhi abacus, comprise frame 1, shelves 2, beam 3 and pearl, it is characterized in that, the described decorative pearl on top of an official cap is made up of the last collar 4, lower collar 8 and web member 5, the last collar 4 and lower collar 8 are arranged on the shelves 2, are equipped with five mobilizable globules 6 on the shelves 2 between the last collar 4 and the lower collar 8.

The web member that the above-mentioned upper and lower collar is 4,8 is a spherical shell, and this spherical shell is provided with opening 7.This opening can enter for child's finger dials pearl.

The web member that the above-mentioned upper and lower collar is 4,8 is the rhombus housing, and this rhombus housing is provided with opening 7.The more approaching original abacus structure of this structure is convenient to accept.

The web member that the above-mentioned upper and lower collar is 4,8 is an arc-shaped connecting rod.This scenario-frame is the simplest, makes easily.

Above-mentioned four following pearls 9 are one group, and from left to right the size of pearl 9 is successively decreased successively under every group.Descend pearl to form a hypotenuse like this, be convenient to the child and understand the height that display of numerical digit on abacus.

Above-mentioned four following pearls 9 are one group, and pearl 9 is made by the material of upper and lower two kinds of contrast colors under every group, and the separatrix of two kinds of materials is from left to right forming oblique line, and this oblique line left side is high right low.

The above-mentioned decorative pearl on top of an official cap from left to right size successively decreases.

The above-mentioned decorative pearl on top of an official cap is made by the material of upper and lower two kinds of contrast colors, and the separatrix of two kinds of materials is from left to right forming oblique line, and this oblique line left side is low right high.

Above-mentioned pearl 9 down is provided with remarkable gear mark.

Compared with prior art, its advantage is:

1, becomes the decorative pearl on top of an official cap and be concrete outward appearance presentation, original one represented five the decorative pearl on top of an official cap be decomposed into visible, tangible, exercisable concrete material object, do not have pithy formula in the study fully, do not need to memorize mechanically yet make up the number or amount, the regulation of complement, can operate naturally and dial pearl, finish abacus mental calculation study.

2, general layout novelty, presentation is abundant: form hypotenuse by the size of setting pearl or in color boundary mode in the utility model, it is just combined with numerical digit, carry out the gear mark simultaneously, size a glance of the height of numerical digit, numeral is promptly seen, total general layout novelty and presentation are abundant, and be concrete directly perceived, guides the child to enter the study of abacus mental calculation especially easily.

3, the utility model is converted into concrete material object with abstract number, and the child is understood easily, can make the child be familiar with numeral easily, grasps the component law of numeral and enters digital fundamental operation, and speed is fast, and mental arithmetic achieves noticeable achievement;

4, product provided by the utility model is beautiful digital toy, is again calculating, opens the intelligence instrument, suits especially to use in the teaching of abacus mental calculation, is child's mathematics and sciences establish a firm foundation in the future.
