To attempt to answer your questions:
1. I wrote activities that wouldn't be considered employment but are still relevant to education and the program to which I am applying (IEP)- volunteer ESL instructor, internship at a homeless shelter, member of community service sorority in college, current membership in a edtech professional development cohort. I am not sure about including sports. It may be interesting to add if it is still an important part of who you are.
2. I am also a teacher and did not drastically change my resume but focused most on parts that were relevant to international ed. and included presentations and research (don't know if this was necessary, as there was space for this on another part of the application).
I'm not sure how helpful this is but it's something. Good luck finishing up your application!
