It's winter, and the cold Arctic landscape is covered with snow. That's not a problem for a lemming, however. The tiny animal has dug a network of tunnels through the snow. Now the little creature leaves its cozy underground home and scurries along the snow tunnels, popping up here and there to find twigs and bark to eat. 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 lemmings and how they are adapted to the extreme cold, but also to develop their powers of observation and critical thinking. Built-in activities, such as guessing how a lemming stays safe from its many predators and figuring out how many babies a female lemming has in a year, give readers a chance to gain, insights beyond the facts and figures.
