oh wow, I've just finished reading about Terry Tao - it sounds like exactly what we'd love to do, and addressing all of our concerns about social / emotional development, balancing his pace of learning with the need for a broad base of understanding and still meeting his needs for ongoing learning and intellectual growth. I don't know if DS has the potential to achieve at the kinds of levels Terry Tao has, but the model resonates strongly with me. It gives me hope that it might actually be possible to do this. I have renewed hopes that it might be worth meeting and talking with schools, although our recent experience has scared me off somewhat.
