Thanks everyone for sharing your experiences.
I wonder if it would be possible to keep DS in the 5th grade math class and then have him do a little Aleks on top of that to fill in any gaps (his schedule is flexible enough to do both, but would it make sense curriculum-wise?). Thoughts on this idea? The following year he could either go to middle school algebra (gulp) or do AOPS pre-algebra.
Ul.H.
Edit: DS really likes the classroom experience and math games, which is why I don't want him to exclusively work with Aleks/AOPS (yet)
Fwiw, this is one of the things I like about DS not being formally accelerated - although he has his own work, he's physically in the classroom with agemates and the teacher can and does include him in the fun stuff as appropriate.
Your plan could make sense. I wouldn't really worry about curriculum ordering and coherence if that's your concern, provided he's enjoying what he's doing; doing things in an odd order and sometimes tripping over gaps that then need to be filled can even contribute to a sense of adventure in a way!
