It would be helpful to know the grade level of the students and ability level. With just 5 students there would be a lot of time for individual instruction in varying skills. You could also do cup stacking with the students if you are familiar with that. Rather than game type activities your lessons would be based more in skill development.

I like the suggestion of team teaching if that is an option, especially if it is a class with special needs. It is amazing to watch students work with others. It is a good time to work on lifelong skills otherwise.
