Nothing up my sleeve. Ask your students to think of an occupation and write down five lines that a person in that occupation would say. Have them read their lists to the class. They are successful if everyone can figure out what occupation is represented. At the end of the lesson help them to see how those few lines helped others to visualize the person and the activity he was engaged in.
Good dialogue contributes to a story by moving it along or revealing character.
Once they start writing, they may use other words not on the lists as long as they fit into this pattern. Now higher level thinking skills come into play. The next step is to choose an image from the third column, and tell why these two seemingly unlike images are related. Fear is a jet black mountain that is too big for me to climb over or get around. Love is a sky blue chair that I fall asleep in at the end of a long day.
