Joyce,
It actually sounds like you're being given a blank check. I know it would be easier if the teacher had ideas and knew what to do. But by looking to you for ideas and goals, the teacher is showing that she is open to doing many different things for your child. Keep in mind that the teacher is probably just as nervous as you are. She knows that her normal classroom teaching isn't going to reach your child. She wants to do something to help. She just needs your knowledge of your child to give her some direction. Even "good" teachers need help sometimes, they just know when to ask for it.
So, what does your DS need? Subject acceleration? More challenge in developing big picture ideas? Do you know what the class is studying this year? Sometimes school districts are helpful and have a curriculum website. Could there be a project that will tie lots of the regular curriculum items together?
Good Luck!
