Here is my unit about the constitutional underpinnings of the United States government.
Part 1: American Democracy
Part 2: Origins of the United States Government
Part 3: Drafting the United States Constitution
Part 4: Federalism
Each part of the presentation has notes. I also included a couple worksheets I use as well. One about Federalism and one about the influences on the United States Constitution. I also have vocabulary matching tiles that can be cut up, mixed up, and then matched together.
