This assignment goes along with pages 8-10 of Magruder's American Government textbook.
They put each purpose into their own words and explain why it is important. This was created as a Google Document and shared via Google Classroom. If you download it and would like that format-I can email it to you.
I am also attaching the slide show answer key - it explains each of the purposes and works the next day to review the information that they read on their own!
