Last year (grade 9) and this year are awesome for me. My youngest is 15 this year.
Activities:
High School after school clubs, including encouragement to enter science fair this year.
Coursera programming course.
Signed up to take a school course on-line to allow an extra elective slot next year. Our school has very good non academic elective choices.
-- I need to help reinforce working on these on-line classes, however, very hands on parenting is required for it to work --
Instructions to find a part time job by the spring or he will be required to referee again this year (he decided he did not like it last year and wanted to quit).
One or two summer camps.
If he stops being helpful (e.g. attitude, sleeping in, video games, no homework ALL the time, not just 90% of the time) he knows it will be back to Cadets once to twice per week. (Daughter was in girl guides for a while when younger)
My oldest started college now, but lives at home. I just transferred over 3 months of her allowance and told her to manage it wisely, and she pays for everything now, including her Zumba class, bussing. She will get allowance until she is 18.
I am so excited about this phase of our lives. I commiserate with all of you, and posted this so you know how great it gets. When the kids were ages 7-12, the goal was to find activities that did not require (much) driving, that did not cost a lot, and only 3 hrs a week, maximum, each, needed from parental support to make happen. Elementary had almost nothing after school until grade 7 with volleyball /basketball.
One area that worked for me was to use church-affiliated programs, like junior choir, youth groups, and of course sunday services / sunday school activities, to round out the "free" or low cost social times. In the end, the church related youth activities naturally built DD's volunteer service hours tremendously and she was able to get two scholarships because of it, which I never expected.
