Another on of my favorite children's books! The Rainbow Fish is a story about a young fish that is asked if he would give one of his beautiful scales to a small fish. After refusing in a rude way, the other fish no longer want to play with him. Rainbow Fish visits an octopus for advice that tells him sharing and being nice is how you make and keep friends. So when he runs into the small fish again, Rainbow Fish decides to give him a scale. Seeing that made the smaller fish so happy, Rainbow Fish begins to share his scales bringing happiness to others. I would read this book in kindergarten to second grade. This book would be a great way to show my students that it is important to share and be nice, so you do not hurt other peoples feelings.
