Hi! What about a board race? 
1.       List the verbs you want to revise on the board/s 
2.       Make columns for �regular�  and �irregular� verbs
3.       Break students into teams
4.       Students write each past form under the correct column � use first verb as an example
5.       Correct answers when the game is finished and ask for examples to check understanding 
I got the idea from TEFL ESL - http://www.youtube.com/watch?v=wam5PscoSjU&feature=related 
I used it to revise different forms of comparative adjectives and it worked well.
Good luck!!!!
