Description

Interesting oral calculation Chinese checkers

The utility model relates to a kind of recreation chess, a kind of entertaining mental arithmetic Chinese checkers of more specifically saying so.

Chinese checkers in the market is a kind of pure physical culture intelligence test recreation chess, and it can only be used for the development of amusement extracurriliar and intelligence, can not be used for children's others such as learning mathematics within the class period.

The purpose of this utility model provides a kind of entertaining mental arithmetic Chinese checkers.It can be used for amusement extracurriliar and intellectual development, be applicable to again in the learning activities within the class period of primary grades children learning mathematics, can help to improve the interest of child's learning mathematics, cultivate the child and learn 100 and calculate ability quickly, strengthen comprehension and quick-reaction capability and imagination the natural number meaning with the mental arithmetic of interior natural number arithmetic.

This entertaining mental arithmetic Chinese checkers comprises: a chessboard, on this chessboard, there are three kinds of different colours to mark the parallel four limit row quadrilateral areas of six congruences, the parallelogram zone of every kind of color with a summit be center order alternately or the outer ring be the chessboard angle of six congruent equilateral triangles, inner lane is orthohexagonal shape, the joining of the line of some equidistant hole points is the hole point on each parallelogram, on the straight line line operational sign of four fundamental rules is arranged between per 2 hole points, with six kinds of colors, the checker of the quantity such as Kong Dian on every kind of color and the above-mentioned equilateral triangle chessboard angle studs with different separately Arabic numerals on the checker.

The utility model is simple in structure, helps the child to learn natural arithmetic rule, improves the ability of calculating quickly, strengthens intellectual development.

Accompanying drawing 1 is the schematic perspective view of the chessboard of entertaining mental arithmetic Chinese checkers;

Accompanying drawing 2 be entertaining mental arithmetic Chinese checkers checker schematic perspective view;

Describe the architectural feature and the game rule thereof of entertaining mental arithmetic Chinese checkers in detail below in conjunction with accompanying drawing.

Fig. 1 is an embodiment of entertaining mental arithmetic Chinese checkers.It is a hexagon chessboard, support bar is arranged all around, available timber, material such as plastics or strawboard is made, alternate row has six parallelogram zones of three kinds of different colours marks on the hexagon chessboard of supported of this piece, they are that the center is arranged in order with a summit, the chessboard angle and the inside that form peripheral six equilateral triangles are orthohexagonal chessboards, ten chess piece hole points are arranged on each chessboard, 61 chess piece hole points are arranged on the interior regular hexagon, have 121 hole points, porose point all on the crosspoint of the straight line line of 5 hole points that the every limit of parallelogram spacing equates, operational sign of four fundamental rules between all hole points and the hole point on the straight line line, by "+;-; *; ÷ " order arrangement from outside to inside, around the centre bore point of chessboard is the division sign, oeprator is corresponding separately identical on the horizontal line on all the other each parallelogram, the regional institute coating colour diagonal angle of six parallelogram is identical, checker useable glass or plastic or other material are made spheroidal or bottom the different shapes such as pagoda shape that socket can patchhole point, inlay on the chess piece or be carved with Arabic numerals, the chess piece of every kind of color has ten Arabic numerals from 1～10.

When using the recreation of this chess, number 2-6 people, everyone gets ten of chess pieces of the same colour, is placed in the oneself chessboard angle, own chess piece is skipped to jumping neat person in the corner earlier for winning, or first returnee is a victory.Utilization wisdom and mental arithmetic ability are lined up and are connected jumping circuit, and manage to stop square chess, and it can not even be jumped.Can only be in the middle of beating every a chess piece at every turn.On institute's checker and the same straight line between chess piece, be compute sign from the nearer symbol of institute's checker, institute's checker with the institute numeral on chess piece for calculating number, the total of calculating is institute's jumping figure, total be several just from the institute every the several holes of chess piece number point, but institute's checker when walking hole count point both straight line walk, also but broken line is walked, but can jump with regard to striding chess piece when counting walking foot, walk the several points of foot after.Just the front can connect again and repeat to jump again only every a chess piece.If total is double figures or three figure places, with the unit numbers is institute's jumping figure, division is determined institute's jumping figure to discuss, no matter remainder is several, if the student has been familiar with 10 with interior addition subtraction multiplication and division, just can practise 100 with interior mental arithmetic, the total of last computation then, must use once in next time, use two chess piece numerical calculation then again, circulation is always gone down.
