Computational and spatial reasoning as well as algebraic thinking are required in this alignment game where chips are moved along the gameboard’s connected horizontal, vertical, and diagonal pathways. One player has five even-numbered chips and the other, five odd-numbered chips. The goal of the game is to create a spatial and numerical alignment which results in an answer of four or five. To play this game effectively, students must know many number sentence combinations of adding two even chips and subtracting an odd-numbered chip (or vice versa) to get an answer of four or five.
