Abstract

The present invention relates to chess for addition, subtraction, multiplication and division, which comprises a mathematics chessboard and mathematics chess pieces. The chess is characterized in that the shape of the chessboard is similar to that of a military chess chessboard, the chessboard is formed from numeral stations and numeral camps according to 12 rows and 5 lines, the number of the numeral camps is 8, and all the rest are 52 numeral stations; the 60 numeral stations and the numeral camps are respectively, longitudinally, transversely and obliquely connected by railway lines and single lines, and one operator of the addition, the subtraction, the multiplication and the division is arranged between a longitudinal connection line and a transverse connection line; the chess pieces have two colors, each color comprises 26 chess pieces, and numbers of 0 to 25 are respectively manufactured on the chess pieces. The present invention pays attention to the cultivation of an oral arithmetic ability and a mental arithmetic ability and integrates entertainment, knowledge and interest.

Description

The addition subtraction multiplication and division chess

Technical field

The present invention relates to chess game, the mathematical chess of a kind of digital operation specifically.

Technical background

Social now popular chess, go, Chinese checkers, military chess, Logic chess, economic ecology chess etc. reach tens of kinds more than, and characteristics are respectively arranged.Colourful skill in playing chess has produced colourful entertainment way.

The chess that suitable children do the digital operation exercise also has many patented claims, such as ZL88103029 " mathematical chess ", and ZL92109422 " a kind of mathematical chess and chessboard thereof " etc., but its laxative remedy dullness all lacks enough interests.

Summary of the invention

Purpose of the present invention just provides a kind of recreational, intellectual, interesting addition subtraction multiplication and division chess of one that be that collects, and cultivates be at play study in the amusement of children and consolidates the interest of mathematical knowledge, improves thinking, the reaction capacity of agility.

Addition subtraction multiplication and division chess of the present invention comprises mathematics chessboard, mathematics chess piece, it is characterized in that tessellate such as military chess chessboard, it forms by the 5 row arrangements of 12 row by counting to stand and count battalion, and wherein 3 row 2 are listed as, and 5 row 2 are listed as, 8 row, 2 row, 10 row, 2 row, 3 row, 4 row, 5 row, 4 row, 8 row, 4 row, 10 row, 4 row, totally 8 numbers are sought, and all the other 52 are the number station; Vertical, horizontal and oblique the connection carried out with railway line and single line respectively with counting between battalion in 60 number stations, lays an operational symbol in the addition subtraction multiplication and division in the vertical and horizontal connecting line; Chess piece has dichromatism, and 26 pieces of every looks have numeral 0 to 25 respectively on it.

The similar military chess of going action rule of the present invention turn over the chess rule, that is:

1, victory or defeat: the son of eating up the other side is for winning;

2, pendulum chess: 52 pieces of chess numerals are attacked in retaliation downwards, put into the number station of chessboard;

3, select chess: turn over the sub-look that the fixation method is determined both sides with agreement method or head;

4, capture: with square two sons in the consecutive number station and the operator between two sons calculate numeral, can eat up any one in the number station of the other side with counting chess piece;

5, walk son: railway is a fast lane, as long as no chess piece stops the corner of can driving straight in; Single line is the single step line, can only make a move at every turn;

6, protection: the son in number battalion can not be eaten.

The present invention is to turn over the chess method owing to what adopt, numeral have the randomness of not knowing in advance, a large amount of capturing will lean on capable chess to constitute formula somewhither, and the other side can stop in the process of enemy operation or it is eaten up earlier destroy the enemy and constitute formula, should calculate the side of getting it right again, side during both sides play chess, thereby antagonism and interest strengthen greatly.

Concrete embodiment

Chess piece of the present invention can be made with wood or plastics, and chessboard can be made with paper or plastics, and both sides all have 26 pieces of chess pieces, and from 0 to 25, distinguish with red and black.

Capture for example:

Example 1: chess piece 20 and 4 are arranged, 4 go to 20 adjacent side counts station (or 20 go to 4 adjacent side count the station), and the operator between 20 and 4 is ÷, constitutes 20 ÷ 4=5, then can eat up several 5 the chess piece of the other side on any number station on the chessboard, but in number battalion, then can not eat the son of number formulary 5.

Example 2: have chess piece 24,3 and 6,6 to go to number station among 24 and 3, form 24,6,3 adjacently respectively, the operator between 24 and 6 is ÷, the operator between 6 and 3 is-and, constitutional formula then

One: 24 ÷ 6=4;

Formula two: 6-3=3,

Three: 24 ÷ 6=4-3=1 of formula; (mixing formula)

Then can be on number station select one in 4,3,1,, eat up the other side's several 1 son, but in number battalion, then can not eat the son of number formulary 1 such as selecting 1.

After the formula of having eaten son will separate once more combination could eat the other side's son again.

This chess is the conversion formula arbitrarily, also can destroy, stop the other side's formula to set up, and can add and can subtract, can take advantage of and to remove, can also carry out addition subtraction multiplication and division hybrid operation, flexible operation, ever-changing, interesting strong, teach through lively activities, arranged in the pleasure, can strengthen child's competitive spirit, cultivate student's adaptability to changes, logical thinking ability and computing power, be the good assistant of kindergarten, pupil's learning mathematics, good tool.

The present invention payes attention to doing a sum orally, the cultivation of ability of mental arithmetic, can accomplish fluently addition subtraction multiplication and division and calculate the basis, reach mental arithmetic accurately, skilled, the purpose of escaping one's lips.Be the recreational toy of exploitation children intelligence, make children remove to learn, review, consolidate mathematical knowledge in being at play, a middle-aged person, the elderly also can recreation and amusements, have certain meaning and value, are worthy to be popularized.

Claims (1)

1, addition subtraction multiplication and division chess comprises mathematics chessboard, mathematics chess piece, it is characterized in that tessellate such as military chess chessboard, it forms by the 5 row arrangements of 12 row by counting to stand and count battalion, and wherein 3 row 2 are listed as, and 5 row 2 are listed as, 8 row, 2 row, 10 row, 2 row, 3 row, 4 row, 5 row, 4 row, 8 row, 4 row, 10 row, 4 row, totally 8 numbers are sought, and all the other 52 are the number station; Vertical, horizontal and oblique the connection carried out with railway line and single line respectively with counting between battalion in 60 number stations, lays an operational symbol in the addition subtraction multiplication and division in the vertical and horizontal connecting line; Chess piece has dichromatism, and 26 pieces of every looks have numeral 0 to 25 respectively on it.
