How to Do the History of Homosexuality, by David M. Halperin

Halperin, David M. (2002). How to Do the History of Homosexuality. Chicago: University of Chicago Press. 208 pages.

Heavy theory, but good for defining some of the key concepts in LGBTQ historical studies. Halperin is a classicist, so he's a good source on ancient Greece and Rome. The second chapter, "The First Homosexuality," begins with a history of the term "lesbian" that could be modified for use with students. Available at the SF Public Library.
