Abstract

The utility model provides a child calculator, including a square frame, a bead rod and a bead. Each bead rod is provided with 9 beads, respectively marked with Arabic numbers 1 to 9 from top to bottom; the square frame on the top of each bead rod is marked from right to left with carry units of 1, 10, 100, 1,000, 10,000 and etc. in order; the cross section of the bead rod is in a square, polygon, oval or double-rod shape; the bead hole is matched with the bead rod, thus making the bead move upwards and downwards on the bead rod instead of revolving forwards, backwards, leftwards and rightwards. The utility model is convenient for children to accept and simple to learn, thus stimulating the study interest of children.

Description

Children's device that counts

Technical field

The utility model relates to and belongs to a kind of children arithmetic education and study aid.

Background technology

Existing abacus mainly is made up of square frame, pearl bar and bead, and bead divides upper and lower two grades, and bead can move up and down freely and rotate on the pearl bar.This abacus is simple in structure, easy to use, is a kind of very simple and practical computational tool.But this abacus is owing to lack strong visual in image property, and its design fails fully to consider children's learning psychologies feature, so children learn to quite feel difficulty, particularly is not suitable as children's the auxilliary instrument of algorithm calculations religion.

Summary of the invention

The purpose of this utility model is the psychological characteristics at children, and abacus is improved, and designs a kind of visual in image, simple and convenient and easy to study easy-to-use children device that counts.

The purpose of this utility model is achieved in that a kind of children device that counts, mainly by square frame, pearl bar and bead are formed, the pearl bar is fixed in square frame in two ends up and down, the bead string is on the pearl bar, all go here and there on the every pearl bar 9 beads are arranged, mark successively on the bead from top to bottom arabic numeral 1-9 is arranged, corresponding mark numerical digit unit on the dextrosinistral pearl masthead end square frame, ten, hundred, thousand, ten thousand etc., the xsect squarely of pearl bar, polygon, oval or two bar types etc., the Kong Yuzhu bar xsect of the bead squarely hole that is complementary, polygonal hole, slotted eye or diplopore etc., so that bead can only be stirred up and down on the pearl bar and can not rotate, thereby the arabic numeral that marked on the assurance bead all the time on top, so that eyes are directly seen.

Principle of work of the present utility model and using method are: according to the decimal notation principle, every lattice 9 pearls meet 10 carries, and every pearl indicates numeral, can reflect various numerals intuitively, and be convenient to computing.Before using bead is arranged in below (playback), up dials into needed number, stir up and down according to calculation requirement again and carry out computing.The utility model can be established the decorative model pattern plate to attract children in the square frame outside simultaneously, excites its study and uses interest.

The utility model can reflect numeral intuitively, and can effectively combine quantity with numeral, is convenient to children and accepts, and is easy to learn, excites interest.
