It's P! begins with an introduction to the letter, what it looks like, and where it fits in the alphabet. In the second section, fun, illustrated sentences show examples of the letter with regard to sound and placement within the words. A cute, rhyming story brings the letter variations together in the third section of each book. Each book wraps up with a fun quiz and a glossary.
