This lovely book reveals the igloo-building process through striking black & white photos and a simple, clear narrative. I recently obtained this book for use with a group of four-year-olds. The book was a hit with the kids, and to my surprise, I enjoyed it even more than they did. The high contrast, sharply detailed photos show just how these fascinating structures go together. The pictures and narrative both communicate respect for the skill and hard work of the Inuit builders, a father-and-son team. I heartily recommend this book to teachers, parents, and children, and also to those interested in documentary photography.
