I liked how this nonfiction book placed the vocabulary words at the BEGINNING of the book, instead of the end.  It’s after the fact at the end.  Appreciated is the no nonsense explanation of the antaomy, food, and lifecycle of fireflies.  The phones with the life cycle was an exceptional touch.  Missing is a geography page where we can locate these creatures on the planet.  Also a scale of size would be nice, how about a page comparing it to a common house fly, bee, robin, etc. so that the students could practice compare and contrast. Also, this reviewer wasn’t able to get to the suggested website, http://readysetflow.org/activitysheets/index.html.  Additional purchase
