I just added a new website to the sidebar of this blog and want to recommend that social studies teachers take a look at Social Studies Central. The site was created by a social studies curriculum specialist named Glenn Wiebe and contains lots of great materials, including information about using technology to teach social studies and a terrific list of online resources.
Above all, I recommend that teachers faced with implementing Common Core take a look at Common Core and the Social Studies Classroom. Mr. Wiebe has provided a comprehensive web page explaining Common Core that is full of useful resources. (Make sure to check out the Slideshare version of his presentation.)
We should all thank Mr. Wiebe for the great work he's done putting this site together.
