Okay, so I know this is last-minute, but maybe you'll tuck this away in a file somewhere and pull it out for next year.
I've run across3 nice sites for lots of Thanksgiving Resources for teachers:
- Larry Ferlazzo's "Best Places to Learn about Thanksgiving"
- Free Tech 4 Teachers' "Resources for Teaching & Learning About Thanksgiving"
- Plimoth Plantation has a great online learning center, plus lots of other links for educators & kids
