I was thinking about a fun activity to help students memorize verbs in the past simple. It is a game like Dominoes, with the first and second columns of verbs instead of numbers. 2 or more students may play the game. Teachers can work on past form, spelling and pronunciation. The student has to read the two forms aloud every time he/she gets a pair. The student who finishes his/her dominoes firt is the winner. The teacher can make new rules for the game.
