Book excerpt: Take a tour around the world to meet all kinds of bears in this delightful pre-reader. Kids love bears and in this book they'll be introduced to them all: Grizzly, polar, sun, sloth, black, and brown. Great full-colour photos reveal details about how and where they live. Perfect for beginning and young readers, National Geographic Pre-readers include simple, expert-vetted text and large, engaging photos on every page. A vocabulary tree at the beginning of the book introduces kids to key words in concept groups, helping kids make connections between words. Plus, a wrap-up activity gives kids a chance to use what they've learned, while expanding their understanding of the world.
