My opinion about Tic-Tac-Toe

I think that this game is very interesting and funny to learn structure. If we have a different and attractive class, we will understand quickly and learn very much. So it's a good alternative to study grammar.
I have another way to study conditionals but I'm not sure if is a good idea, this is create a story with a conditional but the story beggins with a teacher's sentence and then the students continue the story with anothers sentences. At the end we create a long story with only conditionals. The idea is make a story between us.
