Depending on where you live there are many options. In my school district home school kids can join any club or team offered by the public school system where you reside. Additionally there are numerous non-school related clubs and activities all over the place. My kids could play music with the local school district, with a musical education non-profit that is prolific in our area, or ( where they do play music ) with private lessons that have group classes, bands, and performance opportunities.
