I have created a series of math games I use for stations in my upper elementary classroom. Recently I updated my 100 chart to make the squares bigger. (We were running out of dry erase markers, and I wanted to use the plastic cubes as reusable markers.) The game you see above is called Gomoku. Students try to get five squares in a row: horizontally, vertically, or diagonally. To claim a square in this version, they must write an equation that equals the number on that square.
