So, here are a few of my favorite wordless picture books that can be used with young children to help develop the concept of a story. While these can be used as a class discussion/lesson to develop the concept, I also think they could be used for reluctant writers. For a small child, coming up with their own fiction story to write can be daunting (especially if they are expected to come up with a beginning, middle, and end). However, these books provide the frame of the story, but the children would be able to write the text, use good word choice, and define the characters.
