I certainly agree with Prof. Hayden that the tables can present obstacles, and I agree that sometimes the number is all we are after because we want to focus on what it means, not where it came from. My point was that the tables, in consort with the calculator, offer the chance for both a global and point perspective. Perhaps this can be done by more experienced or capable teachers without the table, but I find they seem to help me point out ideas that I feel are important for my students.

I only got a private copy of this and did not see it on the list but it appears to have been intended for the entire list so I quote it here.
I have read many messages from Pat and they sound like words from a VERY capable teacher. Pat's earlier comments about tables made me rethink my dislike for them. The global perspective would be a help to students in seeing how symmetry looks in a table. This is a creative and valuable use of tables, but, I fear, not a very typical one. Is there a way to link the TABLE and CDF functions on the calculators -- or could there be such a link in the next generation?
