Educational arithmetic sets

Abstract

It is disclosed an educational arithmetic game set having a board game. The board game includes four neighboring rectangles around a central rectangle, twelve corner nodes on corners of the four neighboring rectangles, and twelve indexed elements for disposing on the twelve corner nodes. Each rectangle having four nodes, whereas two nodes are shared by the each rectangle and a neighboring rectangle, and two nodes are associated with only the each rectangle. The twelve indexed elements consisting of a four groups of two to four identical elements, each element in a group is indexed by a number in the range 1-4. The twelve indexed elements may be disposed on the twelve corner nodes, such that a sum of numbers associated with the four elements disposed on respective four nodes of each rectangle is the same sum for each rectangle. Each group of two to four identical elements may have a unique color not shared with other group of two to four identical elements. The board game may be included in a computer game.

1 . A board game comprising:
 a) four neighboring rectangles around a central rectangle such as to form a cross board;   b) twelve corner nodes on corners of said four neighboring rectangles, each rectangle having four nodes, whereas
 i) two nodes being each shared by said each rectangle and a neighboring rectangle; and 
 ii) two nodes being each associated with only said each rectangle; and 
   c) twelve indexed elements for respective disposing on said twelve corner nodes, said twelve indexed elements consisting of
 A) a first group of two to four identical elements, each element being associated with the number 1; 
 B) a second group of two to four identical elements, each element being associated with the number 2; 
 C) a third group of two to four identical elements, each element being associated with the number 3; and 
 D) a fourth group of two to four identical elements, each element being associated with the number 4, 
   
       wherein said twelve indexed elements being disposable on said twelve corner nodes, an indexed element for each node, such that a sum of numbers associated with the four elements disposed on respective four nodes of each rectangle being the same sum for each rectangle. 
     
     
         2 . The board game of  claim 1  wherein each element of a group of two to four identical elements is indexed by a number of the numbers 1 to 4. 
     
     
         3 . The board game of  claim 1  wherein each element of a group of two to four identical elements is indexed by a domino-like dot group having a number of dots equaling a number in a range of 1 to 4. 
     
     
         4 . The board game of  claim 1  wherein each group of two to four identical elements has a unique color not shared with other group of two to four identical elements. 
     
     
         5 . The board game of  claim 1  wherein the board game is included in a computer game. 
     
     
         6 . An arithmetic educational game comprising the board game of  claim 5 .
