Another EC question...dance?

so basically I have been a dancer for a large part of my life. since elementary school. Ive danced hip-hop, contemporary, ballet, tap, and even cultural dance. However, i only took dance in high school for two years to get my pe credit, and i didnt want to be a part of my school dance team. Regardless, i still dance outside of school and i have choreographed several different dances for different groups of people. this summer i started giving free dance lessons once a week to children around the community who cannot afford to pay for dance class (often very expensive in my community) I teach hip-hop,jazz, beginning ballet, and contemporary, and we plan on having a back-to-school show and later a winter and hopefully spring show, holding several rehearsals a week. I teach at my cousins vacant guest house, and we would fundraise to rent a small stage for the show and hold it in my cousins (gigantic) back yard. Is this a significant extracurricular?

my other extracurriculars include:
4 years in key club 250+ hours served with them
2 years in french club (secretary this year and part of Inter-Club Council)
2 years of NHS (only allowed in as junior and senior at my school)

i also had a job from aug 2014-feb 2015 and hope to get another one soon to keep throughout senior year.

Yes, the dance related things you do outside of school are definitely ECs. ECs don’t need to be school activities.
