What unit would be complete without great books to incorporate?
Ok, first of all, a few that are old standards, not in any specific book. I always try to brainstorm nursery rhymes and fairy tales as I do my book list. These are all too often disregarded in favor of the newest and freshest. We need to remember however, that these are new to most young children and necessary for a foundation for future literacy. Think of it as the Shakespeare and Homer for preschoolers. Here are two that come to mind on the topic of seeds: Mary Mary Quite Contrary, of course; and Jack and the Beanstalk. Any others you would add?
