In doing science we have recently checked out a book on sloths simply called Sloths (Nature Watch) by Melissa Stewart. This book was horrible. To kick off our unit on an animal I read a 1 page summary on them and then we get an additional book. Well, this book took each little fact and made pages on it, pages I said. Now I am not saying they enriched the material on it or went further in detail. They simply took 1 fact and drug out the wording to take a page. So first strike it wasted words. Second strike is it bored you to death doing it. The we get to decide to embark upon the ice age and evolution. On the whole I strongly disliked this book and will not be using it when my other kids do sloths in the future.
