What's an interesting way to organize United States History units?

Question

I'm taking a class on Instructional Design and while we have a U.S. History textbook to aid us in our project we cannot use the units directly from the book. The teacher wants us to "think outside of the box." I cannot come up with any other way to organize it other than chronological. Any ideas for how to divide and organize U.S History units would be appreciated.

Answer 1

How about geographically? You do one unit each on the north, south, east and west. Show how each area developed from being settled through the present.
