I put together this PowerPoint and eventually converted it into many flipped classroom videos. It is a great overview of the government structures, government authorities, and economic systems that are common in the world. I use this to at the beginning of the year in my world studies/cultures class. The big questions are meant to be question and answer times with the students.
After discussing the introductory unit of the class, students are assigned an island and left to create their own culture, government, and economics.
