Gr. 1. Jaunty paper-cut illustrations open with a picture of a child named Marble, whose color and texture are like gray stone. He invites readers to journey through the Rock Hall of Fame, with the book's following pages giving clues for guessing 12 different rocks. Some answers are easy to guess, but some (sandstone, petrified wood) may require an explanation or some pronunciation guidance from an adult. Labeled color photographs at the end of the book show an actual sample of each rock. The entertaining idea and the appealing pictures make this entry in the Hello Reader! series a fine choice for readers who have an interest in science.
