I agree with the incentive bits. My elementary school had an optional after-school Math Club for 5th graders, but that was mostly around because my dad ran it and was really motivated to foster my childhood curiosity about math.

Maybe an enterprising HOA officer could fund/run it to try to improve home values by getting recognition for their local school.
