From personal experience we have done:
-8th Grade orientation booths
-Hosted a FLL tournament (you don't have to go that far but you could sponsor a team or mentor a team and they would go into highschool knowing someone).
-"Day in the Park", there is a outing every year which clubs at my highschool set up booths and give kids something to do, we took the tenis court and ran our robot around for a while.
-At the begining of the year we have an announcement that there is a meeting in one of the technology education rooms afterschool. We usually get about 5-10 kids in that and we explain what the team offers and what FIRST can offer you towards your future. Most of which stay.
I hope this can help?
