A mini-project to be used when reading Le Petit Prince, specifically after Chapter 5. This can be done in groups, individually, in class, or out of class. The project asks students to create 'warning posters' similar to the propaganda-style posters that were popular during WW2, however these warning posters are about the dangers of being a "grande personne" or an adult. Students can be creative, artistic, serious, or silly, and the guidelines are flexible enough that teachers can allow hand-drawn posters or digitally created posters. Examples are included on the back of the handout.
