what is calculator:
-------------------------
1) A small hand-held computer that performs mathematical calculations. Some calculators even permit simple text editing and programming.
(2) A program on a computer that simulates a hand-held calculator. Calculator programs let you perform simple math calculations without leaving the computer. The Apple Macintosh comes with a calculator desk accessory. Likewise, Microsoft Windows includes a calculator accessory.
-Students simply do better in math and independent research shows that graphing calculators can help students understand math, thus becoming more successful in class, on homework and on exams.

Tell the class what is the calculator for, how it has helped us (a lot), advantages of the calculators, disadvantages, kinds of calculators(solar powered...)and maybe try a sum on the cal showing your frens. Good luck... although some ideas may sound a little babyish.

A one minute speech would take up a whole page of text.
You better do some research.
