@bttocs, take him to Bretton Woods for a nice long day-trip. From the north shore that's about a 3 hour drive (I too live on the north shore), which is not bad if you start early enough to miss the morning rush hour and don't mind getting home after supper. You'll have all kinds of green-blue trails to play on, high speed quads for every lift, and easy-peasy glades off the West Mountain lift that will delight him, once there is enough snow to get them open. The bunny hill is generously sized as well. Nothing around here matches Bretton Woods for learning terrain. You'll be able to get him up every lift, most probably. Stop by the Mt. Washington Hotel afterwards and enjoy the lobby and the views before heading back home.
Sunapee, closer to home but smaller, has a great beginner area separated from the main hill. The main hill will not be for him. Take a look at their trail map and you'll see what I mean about the separation. That beginner terrain even has carpets and an area especially designed for terrain-based learning of first turns. He could play around over there. For a short day-trip and some variety he'd probably enjoy that beginner area.
Teach him to control his speed with two things. First, he needs to complete and even overcomplete his turns on the bunny slopes, then take that to the greens and easy blues.
There's a second thing... if he's traveling too fast for his comfort even with fully completed turns, teach him to modulate his edge angles from pretty flat and skiddy to higher edge angles that provide more grip. The skiddy turns will help him scrub speed. But the turns need to continue to be round, with the turn entry as slowly moved through as the end of the turn.
Sprinkle your lessons with easy things he can do so his confidence builds. Have him shuffle his turns. Have him step his turns (1000 steps). Have him hop in between turns. These things get him centered and are pretty easy to get better at. They are confidence builders.
Try to avoid linked hockey-stops. Bad habits therein lie. Oh but wait, you are an instructor so you know these things. But you're a race coach; maybe you taught him to carve his turns from the get-go. In that case, you might want to teach him to make those round, skidded turns, so he can go slower than a racer would.
