In this chain story-telling game the joker starts off the story with this sentence:
"[Maria] is a teacher." [Any name]

Each participant adds something to the story, either describing Maria or building a narrative.

Like the game "Juan y Juana" in Tecnicas Participativas, the game should produce some interesting elements, a kind of rough image what what we take a teacher to be. This can be made clearer by following with another story, this time starting with "[Maria] is a student."

Follow this with a brainstorm of things that define a teacher and things that define a student. Or draw two figures, one a teacher, one a student.

You could also do this Cuento Vivo style, with the audience taking turns describing a day in Maria's life, and one player pantomiming or acting out the scenes described. (Add other players as needed.)
