Like Shari, our DD (who is also accelerated 4+ yrs) has an "outside of class time" workload which is at times vastly inappropriate to her chronological development and also grossly... er... useless, pedagogically speaking.
So sure, do 40 minutes of Algebra II problems. Not the same four problems ten times each.
The open-ended stuff is, IMO, much more appropriate for GT kids, or maybe it's just better for mine in particular. It's the mind-numbing and completely pointless stuff that she resents and drags her heels on.
