The march towards flipped classrooms continues, and I have another fun resource for you and your educational peers. It's called Crash Course, but the Green brothers.
John Green does WAY MORE than history. He, together with his brother Hank, do lit, chem, ecology, etc. And the videos are fun and easy... a great intro to topics. Keep in mind, you are getting some bias and snarky, mature sarcasm... so you should PREVIEW before you VIEW. But, there are about 40 10 minute videos in US History alone that serve as a great foray into Constitutional underpinnings, politics, and economic theory.
They fact check with educators to make sure they're not getting history WRONG... and they've been picked up on YouTube for Schools, along with the Khan Academy and other vloggers who are ready to bounce into your virtual classroom.
