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

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?
