## Abstract

An educational game for teaching addition and subtraction of whole numbers includes a carpet/game board including ten positively numbered spaces from +1 to +10 inclusive a 0 space and negatively numbered spaces from −1 to −10 inclusive and wherein said positive numbered spaces proceed upwardly in a generally zigzag direction from 0 to plus 10 and the negatively numbered spaces proceed downwardly from 0 to minus 10 and an extra space above the plus 10 and an extra space below the minus 10 wherein the extra space above the plus 10 is a win space and the space below the minus 10 is a lose space. The game also includes a single cube shaped die having six faces with an indication of plus 2, minus 2 and no movement on three of the faces and a plus 1, minus 1 and plus 1 plus and additional turn on the sixth face. Further, the game includes six game pieces of separate distinct colors.
