Cut up the cards and put them face down. Each player has to choose one and say sentences using present perfect telling what they have done at work. The other players have to guess his job.
For example, Player A picks up a card at random.
The other players ask: “What have you done today?”
Player A answers: “I have studied a lot of lines, I have rehearsed with my colleagues.”
The rest of the players will ask: "Are you an actor?"
and Player A will say "Yes, I am".
Then, it's someone else's turn. You can draw pictures in blank cards, write different jobs' names and continue playing.
