Ths is a very fun game to help your students memorize the simple past form of important verbs in English. The focus here is on the irregular ones, but I've also included some of the regulars.
This game is kind of a mix of the tic tac toe and the crossword. The third page of the document explains how to play it. There's also the game's key.
This game is not my own creation, but I've modified and added some rules myself to make it more interesting (in my point of view).
If you've got any ideas to make it even more fun, to improve it in any way, please let me know. I will love to hear it from you.
Hope you and your class have a lot of fun.
