Hi!
I‘ve tried this and it worked really well. They in turns pick up four or five irregular verbs that are upside down on my desk and write them down on the board in the past and past participle forms. Then, as a warm up activity, they get into pairs and think of sentences using the verbs in any tense. Each pair says the sentences aloud. After that the whole group makes up a story adding one or two sentences to the previous one. What makes them laugh is the unexpected development and end of the story.
