This graphic organizer is a wonderful way to allow students to visualize different types of governmental systems. In this package I have included Powerpoint slides with definitions of key terms as well as a note sheet for students.
The PPT slides are in one file, but I highly recommend breaking them up into multiple lessons. I taught on these terms for four days before having my students complete the organizer.
I used this for my 6th grade World Geography students, but this would also be perfect for any middle or high school government class.
