good uses of calculators

Dear colleagues,
We (Al Cuoco, Paul Goldenberg, and June Mark) edit the ``Technology Tips'' column for the NCTM journal ``Mathematics Teacher.'' You may have noticed it in recent issues. We try to highlight good uses of technology, ways to integrate technology with your curriculum, and pointers to technological resources of use to high school mathematics teachers. Recently, we've had articles on the use of dynamic geometry software, spreadsheets, the Internet, and function machines.
We'd like to devote a column or two to calculators, giving short examples of calculator uses that people have found effective either for learning or applying mathematics. We also want to give a few examples of situations where calculators don't help or even get in the way of understanding. By ``calculator'' we mean all varieties, including graphing calculators.
Although it is read by a much wider audience, the ``Mathematics Teacher'' is aimed at the 912 curriculum, and we'd like submissions that relate to that level mathematics. Submissions should be at most two paragraphs. We can't guarantee inclusion, and we may have to combine and edit, but we'll credit the people whose ideas we pubish.
So, what's your favorite activity with a calculator? When is it best to turn them off? More important than the description of the activity is the description of the calculator use that you applaud or boo. And, in addition to how the calculator is used, we'd like to know about the underlying rationale (for example what's the mathematical thinking that it encourages?).
Send submissions by June 9 to techtips@edc.org and cc one of us (alcuoco, paulg, or junem, all @edc.org).
Thanks.
