Since you are inviting comments I can't resist adding a few of my own, although I suspect they will not be very helpful. It seems to me that the very fact that this issue is being discussed in the context of High School is a terrible indictment of the standards of mathematics education in the US. (I would have been more shocked if I had not eperienced this myself in the days when I taught at a large state university in the Midwest.) Let me just say that this year my daughter finished her high school (International Baccalaureate) in Britain. In her final year she did three mathematics projects: one on the Plateau Problem (soap bubbles), one on Fibonacci numbers and one on Statistics. She used Mathematica in all of them, for a variety of purposes, ranging from using Solve to solve equations which would be too complicated to solve by hand even for a professional mathematician, to writing her own simple programs. As for the Gauss trick: she learned it in the first year of her (Japanese) Junior High School. I do not know if there is an age when one is too young to be introduced to computer mathematics (though I suspect it depends on the student). But if there is such a boundary it certainly should not be in High School!
