[close] First published in 1963, Hop on Pop remains a perennial favorite when it comes to teaching kids to read. Here, as in most of his extensive body of work, Dr. Seuss creates uncomplicated, monosyllabic rhymes to foster learning and inspire children to read. But what was radical about this little book at the time of publication (and what makes it still compelling today) is Seuss's departure from the traditionally dull pictures and sentences used in reading primers. In contrast, the illustrations here are wild and wonderful, and the accompanying language, while simple, is delightfully silly. For example, the rhyme "THREE TREE / Three fish in a tree / Fish in a tree? / How can that be?" is brought to life with a trio of plump, self-satisfied fish perched atop globular branches as two stymied hybrid dog-rabbit-humanoids look on in consternation. Hop on Pop does much more than teach children the basics of word construction, it also introduces them to the incomparable pleasure of reading a book. (Ages Baby to Preschooler)
