I think the teacher needs to realize that your daughter is a student, not a coworker there to lighten her load. I was made to tutor after skipping, and it only served to widen the perceived social gap between me and my classmates from both perspectives. It fed distrust in my teachers, making me feel like a second class citizen, because I plainly saw that they felt my right to learn was considerably lower than that of the other students, and that they had taken zero consideration of the negative social implications for me.
Now, that said, in an environment of like-ability students, I can see there being tremendous value in plenary sessions where students present their research to others, including at the elementary level. I don't think there is enough meat to elementary subjects the way they are usually taught for group discovery to be a meaningful learning method for young gifted learners.
