Tracy, It will depend on how large an area you are looking at. Remember, insulating does not produce any heat, it just slows down the transfer between the walls. You will also have to consider how much heat is going into the area you are planning as qa kid's room. the more detail you can provide, the better the response.

As Mark stated, you need to provide heat to the area, either from new ducts from the house or electric baseboards, etc. You can isulated the roof and walls as any normal house would have. The biggest cold issue you will have will be the concrete floor of the garage. Ideally if you can build a joist floor above the concrete floor and put in as much insulation as you can, and use a thermal break by puting ridgid foam insulating panels directly under the joists. If you don't have the room/height for that. Then lay down planton sheets directly on the concrete and as thick of ridgid insulation as you can and then your plywood floor over that, all screwed down with tapcons.
