During the cold winter months, some animals go into a deep sleep called hibernation. Children will learn how an animal prepares for hibernation by stuffing itself with food so that it can survive in its dormant months and how animals prepare safe spots, like dens and burrows, so that they will be protected from predators as they sleep. Full color.

Why Do Animals Hibernate? is aligned to the Common Core State Standards for English/Language Arts, addressing Literacy.RI.1.4 and Literacy.L.1.4. Large color photographs of dens, burrows, caves, and hibernating creatures along with narrative nonfiction text engagingly explain the world of hibernation. This book should be paired with “Good Night, Bears: Learning About Hibernation" (9781448887767) from the Rosen Common Core Readers Program to provide the alternative point of view on the same topic.

This sweet companion to David Ezra Stein's award-winning Leaves celebrates the joy of savoring something you love. Bear is ravenous when he wakes up from his winter sleep and has one thing on his mind: honey! Alas, it is too soon for honey, so Bear tries hard to be patient. The world around him is waking up, too, and he soon remembers all the other things he loves, like warm grass, berries, and rain. He's almost content, until, one day, he hears a welcome buzzing sound . . . and finally it is time for Bear to delight in the thing he relishes above all others--and it is as warm, golden, sweet, and good as he remembered.
