Shelley, these look really good. I'll check them out further at school, my internet at home is really slow. Hope to try them out with a couple of students next week.
You can choose locations and see pictures, read about famous things that happened their and watch videos about why it is important in history. Independence Hall is one of the locations.
I did the summarizing lesson from this site in class today. It had a fun, short video and then several activities the students did together on the interwrite board. They loved it and were very into trying summaries on their own after the lesson.
