What my Daughter-In-Law did was to send two of them to their grandmother (me) and threaten to send the other one (which worked, because he didn’t want to move here). I seem to have a knack with teens.
When I became a foster care provider, I wanted babies, but they sent me teens because I never had any problems with them. I don’t know what the secret was, but I suspect it has to do with spending time with them, allowing them to choose the activities, but keeping busy and a high level of supervision.
When we do work, which nobody likes, we do it together. No one has to clean your room we all go in and clean all the rooms. One wanted privacy enough to keep his room clean just so no one would have to go in and help.
I taught them how to cook, they help with meal planning and grocery shopping. Each gets a list of their share of the shopping. We set aside a part of the house just for the video games, and later the computers. They have very strict rules about putting their dishes in the bus box, and the penalty is not allowed in the game/computer room for a specific length of time.
When I had foster kids, we had a vegetable garden and they all seemed to enjoy working out there. Now we have a pool in the back yard, and of course, that is very attractive. Walking the dog is a privilege to be earned. There are lots of small stuff like that.
When they complain I usually agree with them, because I think they have a right to complain. I home school, so there isn’t a “grade” issue, simply getting the tasks completed.
There is no such thing as getting a bad grade, the only goal of schooling is to learn the material.
