Abstract

The utility model provides a chess for developing intelligence and enriching the extracurricular life of pupils. The 12 cuboid chessmen of the chess are marked with numbers of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12; the specially designed chessboard of the chess is composed of 1 to 12 the twelve numbers, eleven arithmetical signs and three circles. Three numbers are used in doing addition and subtraction operation one time, and thus the twelve number chessmen can be used fourth to do one time addition and subtraction operation. If the twelve number chessmen are used to do one time operation, tens of combination and order arrangement can be formed. The chess is used for one person to play, which can cultivate the independent thinking ability of children.

Description

Independent arithmetic chess

The invention belongs to the exploitation children intelligence, enrich a kind of chess of pupil's after-class life.

The universal arithmetic chess does not have chessboard, and the learning aid that is used to impart rudimentary knowledge to beginners, purpose are to reduce the writing time of learning aid.In existing chess, most of chesses all have antagonism and competitiveness, and for example: Chinese chess, go, military chess etc. all are antagonistic; Chinese checkers, flight chess, Climbing mountains chess etc. all are emulative.

Purpose of the present invention provides a kind of novel single chess that plays.This chess is not to be used for learning aid, but be used for tap intellectual resources, this chess does not resemble has antagonism and competitiveness most of chesses, be that the plus-minus rule of utilization in the arithmetic done sums on chessboard and made up and sequential organization, the correctness of computing, the correctness of combination and sequential organization, whether what decision was moved is.

The main points of this chess are the chessboard of a particular design, chessboard is that totally ten two-digits and " 11 " arithmetic sign and three circles constitute by 1～12, and when having determined that numeral is arranged successively in the direction of the clock, first of 1 position in the upper left corner, when counterclockwise arranging, first of 1 position in the lower left corner.Three circles are designated as the plus-minus numerical digit and are added and subtracted numerical digit.Put on natural number 1,2,3,4,5,6,7,8,9,10,11,12 on the rectangular parallelepiped that chess piece is made by plastics or timber, totally ten two chess pieces.

This chess principle of moving is: plus and minus calculation by add subtrahend, added subtrahend, total totally three numerals form, ten two-digits are all participated in plus and minus calculation one time, lucky four times, ten two-digit chesses are all participated in once-through operation, can form tens different combinations of arranging.When this chess uses this feature to move, according to chess piece, determine a numerical expression earlier, require the person of moving to go to seek corresponding combination and sequential organization then, this has certain degree of difficulty, the intelligence of energy exploit person.When moving, every computing is once removed three chess pieces participating in computing from chessboard, and combination and sequential organization are correct, through four computings, chess piece has all been got from chessboard, otherwise then chess can not have been got.A numerical expression is covered, and can continue to walk other numerical expressions, all numerical expressions that on this chessboard, can set up, and chess piece can both all be covered, and this chess has tens numerical expressions to walk.

This chess is formed with rule as follows:

Form:

A, chess piece: put on natural number 1,2,3,4,5,6,7,8,9,10,11,12 totally ten two chess pieces on the rectangular parallelepiped of making by plastics, timber.(see figure 1)

B, chessboard: by counterclockwise, begin to line up a circle by numeral 1～12 successively from the lower left corner, the centre is provided with " 11 " arithmetic sign, and three circles in the chessboard are designated as plus-minus numerical digit and quilt plus-minus numerical digit.(see figure 2)

The design of this chessboard mainly makes the numerical expression that can not make up with layout be excluded outside chessboard, and all numerical expressions that can set up on chessboard all can make up.

Rule:

1. by digital correspondence position cloth chess, carry out plus and minus calculation by algorithmic rule.

2. determine first numerical expression of moving.

3. chess piece enters into plus-minus and is added and subtracted the seat by straight line.

4. after numerical expression is set up, remove three chess pieces participating in computing from chessboard.

5. four computings are set up, and chess is walked logical.

The example of moving:

Determine the arithmetic formula according to chessboard: for example: 12-3 arithmetic formula

(1) enter into subtrahend and minuend position to 12,3 respectively, promptly set up 12-3, mental arithmetic gets 9, removes 12,3,9 three chess pieces from chessboard.

(2) 4,7 enter into addend and summand seat respectively, set up 4+7, and mental arithmetic gets 11, removes 4,7,11 3 chess pieces from chessboard.

(3) 10,2 enter into subtrahend and minuend position respectively, set up 10-2, and mental arithmetic gets 8, removes 10,2,8 three chess pieces from chessboard.

(4) 1,5 enter into addend and augent digit respectively, set up 1+5, and mental arithmetic gets 6, removes 1,5,6 three chess piece from chessboard.

Four computings, 12 chess pieces have all been got, and the 12-3 numerical expression is walked logical.

This chess can be cultivated children and skillfully carry out plus and minus calculation, can improve children's independent thinking ability; Not only can a people play chess, can be used as again the intelligence test chess.

Claims (3)

1, a kind of by the molecular chess of chessboard draw in chess, it is characterized in that totally ten two and put on 1,2,3,4,5,6,7,8,9,10,11,12 respectively of chess pieces.The chessboard of a particular design, chessboard by 1,2,3,4,5,6,7,8,9,10,11,12 and " 11 " arithmetic sign and three circles constitute.

2, chess according to claim 1 is characterized by when numeral is by counterclockwise arrangement on the chessboard, first of 1 position establishment in the lower left corner, and during by arranged clockwise, first of 1 position in the upper left corner.

3, according to claim 1,2 described chesses, chessboard can be made with paper, plastics, cloth.
