From Jeremy Landa (TEP '09):
I am participating this year in the Yale-New Haven Teachers Institute. It is a program that supports teacher development through continuing education and curriculum development. Anyway, Yale publishes and maintains records of unit plans going back to 1978 for a variety of subjects that New Haven teachers have developed. They are broad enough that many teachers could modify or adopt some of the units.

From Katharine Millet (L&T '10):
Everyone should check out this site too: http://www.dhr.history. It has some great activities for primary source research on specific topics.

From Chris Buttimer (L&L '10; D1 in 2010):
I was a facilitator at a conference this week (July 2010), and a young, high-school ELA teacher from Kentucky asked me if I knew of any high-interest, low readability texts that she could use with her students. So, this morning when I should have been paying attention to the speakers ;-), I whipped this little resource guide out. That being the case, it's by no means exhaustive and is likely a bit sloppy in places. However, I figured it might be a nice resource (or, at the very least, a starting point that could be added to) for teachers who are facing the same issues as the young woman from Kentucky. So, feel free to use this yourself and/or pass it on to any friends in the biz.
Note from Meira: This isn't history/social studies specific. But I thought it was a really terrific resource nonetheless.
