Back in 1957, Theodor Geisel responded to an article in Life magazine that lamented the use of boring reading primers in schools. Using the pseudonym of Dr. Seuss (Seuss was Geisel's middle name) and only 223 words, Geisel created a replacement for those dull primers: The Cat in the Hat. The instant success of the book prompted Geisel and his wife to found Beginner Books, and Geisel wrote 44 books in this series. These affordable hardcover books combine large print, easy vocabulary, and large, bright illustrations in stories kids will want to read again and again. Grades 1 - Grades 2.
