Trying to implement "Screen Free Sundays"

I am trying desperately to come up with some creative new ways to get my teens to unplug. Last week I tried to implement "Screen Free Sundays". The problem is they have to do homework on Sundays. Typically, hours and hours of homework, and the homework depends on a computer which is a screen. How does one deal with the reality and the mom fantasy? I decided instead to compromise and tweak my idea. How about Screen Free Sunday Dinner and quick family game before everyone has to get back to homework Sunday. It is certainly better than not trying. We had a nice long Sunday dinner with all cell phone put away. (I do demand that on a daily basis anyway), played a nice game of cards and at least I knew I tried. As my 16 year old laughingly said to me when I mentioned my "screen free Sunday" idea was "I do give you credit mom, you do keep trying." Those words are enough to keep me fueled to know she actually sort of likes my constant attempts to keep our family together.
