Eye-popping color photos of countable objects from rubber bugs to gummy bears to penguins, introduce the concept and challenge of estimation. Through eye-training exercises to recognize groupings of 10s, 100s, and 1000s, "clump counting" and "box and count" methods, the author helps viewers to train themselves. Whether as a skill-builder, or simple entertainment, this "well-designed book will add zing to many a math lesson and attract browsers as well." - SLJ
