This book is good for learning about how to use punctuation and how important it is. The book could be used in my classroom by learning about expressions in reading and how they help us be fluent readers. We could go over sentences and say them in different manners so choose which punctuation is correct. The book would be useful by reading and showing examples of how important punctuation really is. I think this book would fall in the K to 2nd grade area. The Lexile Level is 650L.
