I can't believe I didn't find this excellent resource earlier. Updated by 3 high school teachers, this blog (and it's two sister blogs for Government and World History) are full of useful links, material, great technology, games, online activities, lesson plans suggestions, videos etc... Perfect for any social studies teacher. Or for the curious amateur historian. I will definitely be referencing this site regularly.
In their own words, "this site is made by high school US history teachers and will have links to useful classroom sites, relevant articles, other useful blogs and more."
This isn't my typical "Links to History" where I share emails I've received from other sites and publishers and vendors... this is a blog I found this morning and had to share. Teachers, you have to go to this blog.
