oops...meant to add that while they sell a FABULOUS and well priced curriculum - there is a FREE podcast online for most of their programs with short relevant video episodes that go GREAT with class...just look them up on iTunes "The Choices Program"
While to get the full version you must buy the curriculum for any given topic (which I will say I have found to be VERY worth the money they charge if you are interested in purchasing), for any given curriculum set, when you select it, on the right side you will see a box that says "supplemental materials". This is a link that gives you access to graphic organizers, video clips by historians, etc all good stuff you can use in your lessons!
