This chapter book is suitable for readers in the 2nd to 3rd grade. Incidentally, there are a few words that may be up to the 4th grade level. The book can be classified as non-fiction. However the facts are told in an easy and sometimes humorous style. The narrator is a whale shark who is determined to dispel some of the myths about sharks. The author thinks that "Growing up Shark" could generate a lot of discussion, because many of these myths have been around for a long time. It would be nice to find out your kid's opinion on these myths.
