content: I got this book as part of a curriculum package for my second grader. I decided to pre-read it to see how it was, because a lot of people had mentioned problems with it.Boy, were they right!You can't read a single chapter without finding an inaccuracy. The tone of the book is condescending. The viewpoint is emphatically Christian. I know some Christian home-schoolers have complained that the book isn't Christian enough, but what they seem to mean is that it doesn't hold to their anti-evolutionary ideas. I have the most recent edition and much of the racism in the prior editions has been removed, but this is absolutely not a secular resource, not can it be easily secularized. Later in the book, as it gets into modern times, the text is not longer the story of history but rather a litany of atrocities. It's no longer a story, and neither interesting for nor suited to early elementary students.I spent extra money on a different text.
