Why do animals have tails? Parents and kids take turns reading about awesome animals and how their tails help them move, communicate, and stay safe. Do you know why peacocks fan out their colorful fancy feathers, or how opposums hang upside-down from trees? Whether to seek attention, keep their balance, or move from place to place, animals have tails for a lot of different reasons. This Level 1 Co-reader takes readers around the world to meet some kid-favorite and exciting new creatures whose tails have remarkable abilities. Learn how dolphins use their powerful to swim up the Amazon River, why a pangolin uses its scaly tail to curl into a ball, and how a mom and baby spider monkey swing from tree to tree with their long, fluffy tails! Each page features compelling descriptive text and engaging photographs along with fascinating facts. Fun activity pages allow parents and kids to engage with the content even more while also building vocabulary. National Geographic Kids Readers have been solid performers in the beginning reader category, and this book builds upon that success with a different approach--parents and children reading together. With the same combination of careful text, brilliant photographs, and a fun approach to high-interest subjects that has proved to be a winning formula with kids, National Geographic Co-readers provide one page of adult read-aloud and one page of kid read-aloud text on each spread, facilitating a collaborative reading experience.
