Empires were falling left and right seemingly during Ancient Mesopotamia. Here's one your students will really get behind, their own empire! They will explore concepts of Geography, reality, and creativity to determine how they would rule and run a country in Ancient Mesopotamia. They have some mandatory elements, like considering what natural advantages a the area (of real life countries) present including resources and water access, as well as fun elements like glad creation, culture, and how they would run a government.
My students LOVE this project and end up learning a lot more than they realized as they created their resources.
