Chess set has been historically used to play chess for fun and also in chess tournaments. The invention of this chess set is to teach children math in addition to learn chess. The chess set is comprised of 32 chess pieces, each said piece has an indicia uniquely marked using geometry concept of lines or line segments on one chess piece in square shape. The permissible mobility and its direction of each said piece are therefore completely identifiable to facilitate the learning of chess. Each line or line segment on a chess piece can be highlighted on one direction to indicate its actual move direction. This highlighted portion on a line or line segment creates a geometry concept of ray to indicate its intended move direction and can be incorporated with arithmetic to show its operation orientation such as order of operation in math.
As discussed in greater detail below, the present invention differs all of the prior art in that it truly utilizes the concept of geometry to create the symbol of each chess piece based on the line, line segment, and ray of geometry transformation.
(1) Field of the Invention
It is the objective of the present invention to provide a chess set which can be used to teach beginner chess by using basic geometry concept. With the built in geometry concept on the symbol of each chess piece, each chess piece has the capability to indicate its orientation and thus the additional objective of the present invention is to integrate this chess set with math to allow the operations of addition, subtraction, multiplication, and division in the direction of using chess moves as indicated. The third objective is to use the unique feature of indicated move on chess symbol to create chess mazes. This criteria of operating math problems or chess mazes is achieved by darkening or thickening part of line or line segment to create a ray (only one move direction in geometry) to indicate its move direction.
(2) Description of Related Art
Many chess sets have invented for the purpose of playing chess. The Margetson's U.S. Pat. No. 3,608,904 chess set has symbols on all 4 sides thus no “blind” chess can be played. It was not specifically tied to the geometry concept since it does not distinguish the definitions of line (with arrows at two ends) or line segment (with no arrows at two ends). For example, the move directions showing all arrows in Margetson's design for all chess pieces regardless how many squares each piece can actually move to. Pawn (
Margetson's chess set only shows all possible moves and is not designed to show any specific one direction of move (geometry concept of ray) and how it is tied to math education.
Margetson's chess set has the symbol of chess on one side and the move of the piece on the other side. Due to this reason, Margetson chess set can not be used to play blind chess (A chess game is played in such a way that one's chess indicia can not be seen by the opponent.)
In the prior art related to U.S. Pat. No. 5,171,018 (Zhang), Zhang's invention does not use chess pieces moves but to use pieces of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, +, − *, div., and X and Y to form algebraic expression. Further, Zhang's invention relates to such a game and its playing method wherein both of the ability of algebraic operation and the playing skill of Chinese checkers are required.
It is an object of the present invention to provide a new and improved chess set to be used in conjunction therewith in connection with which it is possible to facilitate the chess teaching.
It is another object of the present invention to provide a new and improved chess set to be used in conjunction therewith in connection with which it is possible to integrate the teaching of chess and math.
It is another object of the present invention to provide a new and improved chess set to be used in conjunction therewith in connection with which it is possible to create chess mazes.
In order to achieve the objects set for the above and others, the present invention makes use of the geometry definitions of line, line segment, and ray and the geometry transformation rotation concept of central point to design a new chess set.
The specific direction of chess move of each chess piece can be shown by having a darker line or line segment, in this manner this highlighted line or line segment of each chess piece can be used to visually teach the operation of addition, subtraction, multiplication, or division, i.e., an fun way of learning math.
The following drawings are illustrative of embodiments of the invention and are not meant to limit the scope of the invention as encompassed by the use of claims.
Referring to the accompanying drawings wherein the same reference numerals refer to the same or similar elements.
Each chess piece is in the shape of a square and different colors could be used to indicate 2 chess players. The indicia on each piece is the symbol of each chess piece's permissible move and only printed one side of each chess piece. No other symbols are printed on any other sides of each chess piece. This feature allows chess pieces to stand up to play a game which the opponent can not see the indicia of each other's piece. All chess pieces have a central point placed in the middle of each squared chess piece. This is in line with the geometry concept of using the center point as the transformation point to move around.

The entire design of these chess pieces is to use the concept of line and line segments in geometry to show where and how each chess piece should move and to achieve the purpose of “what you move is what you see”.
The present invention also use the geometry of ray to indicate one specific direction by darkening the line segment from the central point to the end and thus create a ray which is in line with the geometry concept that is ray only has one direction. The following
By darkening line or line segment (and thus creating the geometry concept of ray) on the symbol, each chess piece can display specifically as to its pointed direction of move, these directed moves allow the arithmetic problems such as “order of operation” to be conducted.
