The Ancient Greece packet contains a variety of materials. Although not a stand-alone unit, it is intended to supplement and complement the resources you already have. It contains notes on geography and history, some quizzes, an abridged version of Plato's "Myth of Gyges," an activity to evaluate online games, a word search, and more. Much of the material is appropriate for challenging stronger students, but can certainly be modified for more general use.
Best of luck, and enjoy exploring anc
