I have loved looking at new websites to teach with today! I am particularly excited about using the social studies sites from National Archives. The Digital Vault activities they have, with digital copies of primary sources is phenomenal and engaging. It will be a great extension activity as well as an any way to expose students to numerous primary sources, and to learn how to read and analyze their value in research. I am also interested into delving into the National Archives lesson plans.
I also really liked the game generator on ClassTools.net because it allows students a choice in which type of arcade game they want to play, but uses the questions that I want them to answer/practice.
