Magic Tree House Research Guides are now Magic Tree House Fact Trackers! Track the facts with Jack and Annie!   When Jack and Annie got back from their adventure in Magic Tree House #27: Thanksgiving on Thursday, they had lots of questions. What was it like to sail on the Mayflower? Why did the Pilgrims choose Plymouth? How did they survive in their new home? What did they really eat at the first Thanksgiving? Find out the answers to these questions and more as Jack and Annie track the facts. Filled with up-to-date information, photos, illustrations, and fun tidbits from Jack and Annie, the Magic Tree House Fact Trackers are the perfect way for kids to find out more about the topics they discovered in their favorite Magic Tree House adventures.
