We have been avid fans of sharing picture books with children for over twenty-five years. For at least a dozen years, we have seen the wisdom of using extensions with picture books. Extensions allow children to think about a book in a new way. They extend and reinforce the content of the story and aid in comprehension. Extensions provide a natural tie-in to various areas of the curriculum. Most importantly, extensions motivate children to read and, thus, promote the love and joy of sharing books.
