The summative assessment I used at the end of my middle school ancient Greece unit. The project has two main parts:
1. The students choose a "patron" Greek god or goddess and research their origins, family, powers, etc.
2. Students create a city-state based off of either ATHENS or SPARTA and complete a chart listing their city-state's attributes.
3. (Optional, but my favorite part!) Students create a poster that shows their city state. I had my students tape their charts and info sheets to the back.
My own personal rubric is included, but it's entirely up to you!
