Dona and Dino's professions

Lay out cards with all sorts of professions, trying to also include some atypical professions, such as pianist, journalist or lifeguard. Divide the blackboard into two halves, one for Dino and one for Dona. The pupils can get up spontaneously, take a card and place it on whichever side of the blackboard they consider appropriate according to the gender to finish with a collective conclusion.
