"Zebras are one of Africa's most interesting animals, and in this pre-reader, young readers will learn all about where they live, what they eat, and how they survive in the herd. 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 them make connections between words. Plus, a wrap-up activity gives kids a chance to use what they've learned, while expanding their knowledge of the world".
