Time4Learning is awesome in the summer, but what about when you're on vacation?

I found a great website called Teaching with Historic Places. They have a searchable database so you can find historic places near you, or along your vacation route, and free lesson plans too.

Teaching with Historic Places (TwHP) uses properties listed in the National Park Service's National Register of Historic Places to enliven history, social studies, geography, civics, and other subjects. TwHP has created a variety of products and activities that help teachers bring historic places into the classroom.
