Tundra wolves racing through the snow, huge furry musk ox lined up so it's a bit of a challenge to count them, arctic terns flying all over the page, puffins, wolves, caribou—this book is a marvelous lesson in polar animals even as it teaches young readers to count backwards. There is an opportunity to learn new but simple words in context, as penguins romp, stomp, and swim in the icy water. There's even a chance to teach the concept of camouflage as children count eight arctic hares that look like little lumps of snow. Brilliant and interesting photographs and short, informative text are the highlights of this work in the "A + Counting" series, which also features titles on counting, counting by twos, more, or less. There is a very short index (which even includes the numbers themselves), a page of interesting facts about the animals, a glossary with words like arctic, antler and waddle; and a list of additional books and reference to the www.facthound.com Web site, with links to age-appropriate sites for each book. This is an outstanding series of concept books for new and pre-readers; the photographs make the book interesting enough to use with older children who are English language learners.
