We took E.Q. notes from the last, remaining slideshows of empire case studies. I provided a few clarifications for students to add to their E.Q. notes. In 5th hour the Context & Lens work pages for empires was returned, discussed at length, and edited. In both classes we began a Claim & Evidence (circles) work page on the History Channel video "Engineering an Empire: Persia" -- to be finished in class tomorrow.
