Its a spring morning in the Arctic. A hungry female polar bear emerges from her den after a winter spent sleeping under the snow. Her two young cubs follow her into their icy new world. The tiny bears have lots to learn. When they get to the ocean, their mother will show them how to swim and hunt for food. Filled with information perfectly suited to the abilities and interests of its primary-grade audience, this colorful, fact-filled book gives readers a chance not only to learn all about polar bears and how their bodies are adapted to the extreme cold, but also to develop their powers of observation and critical thinking. Built-in activities such as investigating and measuring the size of a polar bears paw will give readers a chance to gain, insights beyond the facts and figures.
