So much good and useful discussion here.

I really agree with HowlerKarma about the perfectionism. That usually showed up as an inability to even start a project or tearing up work that wasn't what she wanted. Percy's comment about breaking things down into manageable chunks worked for us too. I noticed the school doing this on a recent assignment they sent home. Different parts of the assignment were assigned to different days with two deadlines to meet for part A and Part B. DD didn't need that but it would be good for less organised kids.

HowlerKarma is also spot on that there is a limit to how far you can go with acceleration without stretching the bounds of the executive functioning of a little being. Our DD is till a little person in so many ways and we are mindful of that.

It's interesting about the creativity. School can stifle it at times. DD gets really upset if an assignment is too rigid in its layout and she has no scope for creativity. Be that introducing colour, different fonts, interesting layout. Hope you find some more outlets for your DDs creative spirit. Creativity is as important as academic achievement.
