Practicing grammar through role play is an effective, enjoyable way to repeat structures and vocabulary. It isn't too difficult to write your own dialogs for your students, or even get them to write their own after you have taught them the new structure. Collect all the student-made dialogs, check them, type them up and distribute them to other students for practice. Furthermore, you can keep them in a folder and use them with your next class when they start the same section. See the list of grammar dialog scripts on this site.
