I like this book because it is an easy read informational textbook. The author uses a variety of text features like large text, clear pictures with captions, and a table of contents to help readers navigate through the pages of the book. I also like that the author presents the most relevant information on the topic of gemstones so that children are not reading a bunch of information that they will get lost in. The big idea of this book is to help students understand what gemstones are. ( )
