Help her start a Roth IRA. If she questions why she needs to think about retirement, teach her about compound interest. Put money away for savings, clothes, eating out, entertainment with friends, school (field trips, football games, etc), Christmas/birthdays, maybe a little for charity too. If she doesn't have a car, savings for a car or if she does have one she can pay car insurance to get used to paying bills (if you don't need the money, you can always save it for her and gift it back when she moves out)
