Make the tic tac toe court. Split students into two teams. Demonstrate what three in a row looks like. Each team will have a set of colored balls, spots, or Frisbees. A person from Team 1 will throw their object attempting to land the object in an open square on the game board. Then a person from Team 2 will do the same. The team to finish the tic-tac-toe first, either horizontally, vertically, or diagonally signals the start of a new game.
