This is an activity that can be used at the beginning, during, or the end of a story. You be the author lets the student continue the story, either through what they predict, or what they want to happen. Giving the beginning lines of a story and having the student finish, or reading an entire story and not reading the end are both wonderful suspense opportunities. COnducted during a story allows critical thinking, allowing students to change something they did not like, or allow them to elaborate on something they did like. A prime example of the activity is seen in the book "The Mysteries of Harris Burdick," by Chris VanAllsburg.
