Abstract

Abstract An educational board game for up to four players. The game equipment includes a square game board, a plurality of strips on each of which is printed an algebraic equation or inequality to be solved. The strips are color coded to reflect the relative difficulty of the equations and inequalities thereon. A plurality of similarily coded markers are also provided. Each marker has printed thereon a portion of an equation or inequality. The board is provided with areas adjacent each side which are demarcated to receive, firstly, an equation or inequality strip and, secondly, a plurality of markers which are placed on the board during the play of the game by the players in their efforts to solve the associated equation or inequality. The equipment also includes a plurality of timers having different timing periods, a selected one of which is used to time the game. After a timing period, the board is rotated 90 degrees to allow the players to check the work of each other.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 107 words
An educational algebra game article comprising a generally square game board, a plurality of strips each having printed thereon an equation or inequality to be solved, and a plurality of markers having printed thereon portions of equations or inequalities, said portions being so related to respective ones of said strip equations or inequalities that selected ones of said markers can be assembled to form a successive series of equations or inequalities the last of which constitutes a solution for the related strip equation or inequality, said board including demarcated areas adjacent each side thereof for receiving one of said strips and an adjacent assembly of said markers.
Claim 2
Dependent Claim 107 words
An educational algebra game article comprising a generally square game board, a plurality of strips each having printed thereon an equation or inequality to be solved, and a plurality of markers having printed thereon portions of equations or inequalities, said portions being so related to respective ones of said strip equations or inequalities that selected ones of said markers can be assembled to form a successive series of equations or inequalities the last of which constitutes a solution for the related strip equation or inequality, said board including demarcated areas adjacent each side thereof for receiving one of said strips and an adjacent assembly of said markers.
Claim 3
Dependent Claim 18 words
The article as defined in claim 1, and further including means for timing the play of the game.
Claim 4
Dependent Claim 36 words
The article as defined in claim 2 wherein said timing means includes a plurality of timers having different timing periods, a selected one of which is used to time the play of the game as desired.
Claim 5
Dependent Claim 30 words
The article as defined in claim 2 wherein said board is further provided with a central area for receiving said timing means and a random unassembled array of said markers.
Claim 6
Dependent Claim 46 words
The article as defined in claim 1 wherein said strips are provided in groups each having inequalities or equations of selected difficulties, said strips being color coded to identify them as members of the various groups, and said markers being provided in correspondingly color coded groups.
