My first grade students loved this book! They were really amused how the little fish made little assumptions like, "And he probably won't wake up for a long time" and the picture would show otherwise (the big fish was actually awake!) This book served as a great mentor text for teaching the strategy of asking questions. Using turn & talk, the students asked questions before, during, and after reading. I kept adding them to our "Good Readers Ask Questions" chart. The book is not that long, but make sure you give the children enough time to look closely at the pictures to see how they contradict the main character's thoughts. The students came up with lots of questions that were left unanswered after reading which led to a very lively and engaging discussion! I highly recommend this book for early primary.
