How to play Omok
Students play in pairs. The students take turns choosing a square and saying the vocabulary associated with it. Students can either say the word or a target sentence prompted by the word. If they say the word/sentence correctly, they get to mark that square as theirs. Cunning strategists will then try to block them by placing their own mark nearby on their turn. When they own five squares in a row (diagonally, vertically, or horizontally), they are the winner.
It's like a bit like tic-tac-toe, but with the goal of getting five in a row on a huge grid.
For the sake of not making endless copies of the worksheet, I put the Omok grid inside a clear file and give the students whiteboard markers in different colors (and erasers, of course). I believe my coworkers refer to these clear file folders as "L-cha files," if that helps you any.
