Because just a few sentences of text on each page are accompanied by large color photos supporting the text, this book is a good tool for emergent readers.  Because all text is presented in both English and Spanish, it is good for language learners.  Often I find it a handicap when a non-fiction book is intended for emergent readers, because I find them light on information, but because this is a topic about which students often have little understanding, this volume is sufficient to give them a brief overview of how igloos are constructed, by whom, and why they are designed as they are. I learned several things myself.
