I purchased this book for my first grade classroom. We do a unit of study on the elements of a non-fiction text. The Time for Kids books are wonderful for this unit. They have terrific pictures (which the kids love), and many elements of a non-fiction text, such as labeling, comparisions, captions, glossary, types of print, etc. I would highly recommend this book - really all of the time for kids books - to those looking for appropriate non-fiction books for a first grade classroom. The level 1 and 2 books are most appropriate.
