Sylvan Dell Publishing is a small and relatively new press out of South Carolina producing high quality books for younger children. Their tag line is "science and math through literature". Unlike many efforts in this vein, these are good stories that happen to impart knowledge through good writing and superior illustration. The noble intention of imparting knowledge fortunately does not suffocate the story telling.
They have twenty-five titles in print and if you are teaching kindergarten through third graders anything to do with the environment, ecology, animals and marine life, and related topics, it is probably worth visiting their site. They have lesson plans, activity guides and links to related websites, all arranged by title. They also have their titles aligned to various state and federal standards. Finally they also have them measured according to the Lexile, Accelerated Reader and Reading Count measures. We carry their full range of books.
