It'll be interesting to see what kind of response you get to the classes. I live across the street from an elementary school with about 300 students, about two-thirds of whom live within a mile of the school. Every morning there will be from zero to three bikes in the rack out front, and 150 SUVs dropping kids at the gate. The principal is a friend and a cyclist, and we've offered classes twice teaching kids and parents the basics of bike repair, fixing flats and doing minur adjustments. Got two takers the first time and none the second.
