I've been a fan for a while of the early elementary school series: Blast to the Past, by Stacia Deutsch and Rhody Cohon. The books are about a group of third graders who travel back in time to keep history from getting out of balance (an enemy is also traveling back and causing problems). Each title features a different historical figure, from Ben Franklin to Walt Disney. (I reviewed the Ben Franklin installment here.) The books are a nice, fun way for kids to get a dose of history. And who isn't fascinated by time travel?
The publishers of the series have an offer for teachers. They are offering a free teacher's copy of the book Lincoln's Legacy, along with a teacher's guide. They ask that you email requests to email@example.com. I know how people love free books, so I wanted to bring this offer to you attention. The series won the 2007 Teacher's Choice Award by Learning Magazine.
