I first came across Anthony D. Fredericks' non-fiction texts as a classroom teacher. He has written a whole series of non-fiction picture books that explore habitats such as soil, ponds, and tidepools. Each book is packed with information on species within the habitat, presented in a rhythmica, cumulative text (think: "There Was an Old Lady Who Swallowed a Fly" or "The House that Jack Built"). My preschooler enjoys both the predictability and the repetition of the text, and the bright, colorful illustrations.
