I've had a couple of commenters say that they can't locate the Episode Guides on The History Channel website.
Go directly to this link. They should be right on the left-hand side (scroll down a bit) titled "Classroom Episode Guides". Click on the episode of your choice and it will pull up a pdf for you to print.
Here is the link for you to copy and paste if you need to: http://www.history.com/shows/america-the-story-of-us
I hope this helps! Let me know if you are still having problems finding it.
