Have him do figure eights... many of them. Then go high up then have him cut the throttle and tell him to land it - dead stick practice. He will have butterflys in his stomach for a while, especially the first flight of the day.

What I do after a few weeks away is to take off then fly several orbits with left and right hand turns - figure eights. Then I start to do approaches without landing. Then, I work my way to the ground and do touch-and-go's followed by full stop landings. I do that before I do anything else.

Since I fly mostly glow powered planes, I run through at least one tank doing the above, then, once I begin to get comfortable with my flying, usually the second or third tank, I then begin with maneuvers.

You're doing a good thing for him. It's always nice to get rid of the rust with an instructor, or with someone with experience.

Good luck with it.
