This is a website I created on wikispaces to share geography we cover in class. I also use this site to communicate weekly assignments they must complete in class.
For those teaching Number the Stars by Lois Lowry, this site has website-accessible or printable questions, activities, and resources. I've noticed a few errors in the web-based comprehension questions, but otherwise very helpful!
I know some of us in the high school are using the book. The video and games are interesting and the kids seem to enjoy the supplemental information. (I thank Judy for originally sending me this link!)
