Keeping Seniors Attention

This is my first year with seniors and I am losing their attention FAST. We end school in mid June. I tried doing fun activities but they could care less about ANYTHING school related at this point.

If you teach seniors, how long do you teach for before you transition into fun end of the year activities? What are your end of the year activities? Do you show movies and if so do you have any good suggestions for a low level ENGL class?

If you're a student, what activities do you actually enjoy at the end of the year?
