This is a webpage written by high school teachers for those who teach US history who want to find online content as well as technology that you can use in the classroom.
The Historypod daily video is a great resource for teachers. Each day, Historypod releases one short video focusing on a single topic occurring on that date. The scope is broad and covers all world history. Just this month, for example, they released a video (2:44) on the 1968 My Lai Massacre,
assassination (in 44 BCE) of Julius Caesar (2:40),
and the first case of the 1918 Spanish flu (2:58).
The teacher behind Historypod also has a website with lots of terrific resources. Click here to see it and you can follow him on Twitter @MrAllsopHistory.
