I have found that History.com has so much more than just articles. There are videos, images, maps and sometimes interactive games students can play. Vietnam is a difficult war to teach any resource like this makes my job easier.
My students all love Mr. Bett's class. His video parodies are amazing. He takes popular songs and makes the lyrics about a time in history. This one in particular was a hit with my students this year. I gather the actual Gucci Gang son was a little risque, so my students were super thrilled to listen to this video.
Who knew Kahn Academy did History? Kahn is a favorite for any educator. Their content is always spot on. In this case I really loved the maps that were given. Geography is a skill that is not taught as much as it once was.
