As we work through our fiction writing unit, we've talked about how finding ideas for stories is sometimes very difficult.
Lucy Calkins, author of Units of Study for Teaching Writing, has this advice:
Think about an issue that is important to you and create a character who struggles with that issue.
As an example, we read "The Fan Club" by Rona Maynard. You may want to check it out, and see how the main character, Laura, deals with the issue of discrimination.
