Mr. Green takes his class to an aquarium, where they discover how sharks' teeth grow in rows-and keep growing for life. Many sharks are gentle and eat only plankton. Others, such as blue sharks, are very dangerous.
With the obsession of Shark Week in our culture, I thought having this informational book about sharks would be great to have in the classroom. I enjoyed reading this when I was younger, and I think young students would like to learn more about the species.
