In this Gallery Walk/Project file I have 8 Greek city-state handouts, a brochure handout, and a foldable/graphic organizer the students can use in a gallery walk.
I break my students up into 8 groups and assign them all 1 of the city-states (usually I walk around with the names of each city state in a Styrofoam cup and the kids pick their city state from the cup). Once all groups have been assigned a city-state I pass out the handout that goes with that group. They have one class period to make a brochure inviting people to their city-state. On day 2 we post the brochures in the hallways and the students go from brochure to brochure filling out their graphic organizer.
