"I'm the Cat in the Hat, and we're off to have fun. We'll visit the planets, the stars and the sun!" And so Dr. Seuss' famous Cat in the Hat whisks young readers off on a fun-filled tour of the solar system. This title and others form part of a series of books that takes an off-beat look at nature and natural sciences through a fun combination of Seussian rhymes and zany illustrations. Aimed at early readers -- from four to seven year olds -- the books are designed to bridge the gap between concept books written for preschoolers and more formal non fiction titles that require fluent reading skills. By presenting the facts in a lively and rhythmic manner, they provide the critical foundation upon which complex facts and ideas can eventually be built.
