I really enjoyed the Scholastic webcast from the Plimoth Plantation. I hope you all got a chance to see it with your children too! (If you didn't just click the link to watch!) Being able to see actual people speaking in dialect from the time and wearing period clothing has managed to breathe life into obscure concepts like dress and traditional customs for my kids.
Scholastic has also pulled out all the stops, presenting an abundant resources page on their site. It's a great spot for homeschoolers wanting to teach about Thanksgiving because everything from lesson plans to crafts are organized and presented in a way that makes teaching a breeze!
A really nice touch is the Historical Letters section. They not only offer the written letter but you have an option to hear it read aloud! (A bonus for hearing unfamiliar vocabulary spoken aloud.)
The following is a fictional letter from a Wampanoag — The Feast of the Pilgrims.
