Bill Martin Jr. and Eric Carle are two of the most respected names in children's education and children's illustrations. This collaboration, Polar Bear, Polar Bear, What Do You Hear?, their first since the classic Brown Bear, Brown Bear, What Do You See? (published decades ago and still a bestseller) shows two masters at their best. What will you hear when you read this book to a preschool child? Lots of noise! Children will chant the rhythmic words. They'll make the sounds the animals make. And they'll pretend to be the zoo animals featured in the book-- look at the last page!
