The digitally colored pencil illustrations with some photographic elements are dear, with an appropriate level of simplicity and lots of negative space in its white, pastel blue, or yellow backgrounds. The puppy’s soft curves and spots provide a distinctive visual counter to the beveled edges of the blocks. Quaint independent learning.
Harris succeeds in describing block shapes ("1. 2. 3. 4 corners. 1. 2. 3. 4 straight lines—all the same size. Hey! This is a square!") and Puppy’s trial-and error-process in kid-friendly terms, providing support for young builders who might not see the design flaws right away. Readers should pair this book with real blocks for a tail-waggingly fun building session once Puppy settles in for a well-earned victory nap.
