This project is so much fun for any student learning the subjunctive. They get to cater their learning to a snappy rhythm. All they have to do is change the lyrics to a classic tune and make it grammar related. I have had great success with this in my classes---the kids talk about it for years to come!
The worksheet includes a grading rubric, as well as a pre-chosen list of classic songs for students to choose from ranging from oldies to today's hits.
This assignment can also be easily adapted to be a final project in place of an exam if desired.
