The Graphing Calculator Page

Texas Instruments Graphing Calculators and Computer Software have had a tremendous impact on mathematics education. Not only do they realize the power of visualization, but they change the content of mathematics curriculum and allow for real discovery learning to take place. The calculators are affordable, portable, and powerful. And their programmability makes them as versatile as a computer. Here's some stuff for you. Enjoy.

A Slope Field Activity (zip file) based on 2004APCalcAB6 for TI-Interactive.

Slope Field Laboratory (zip file) is a 3-page TI-Interactive document that allows for interactive, graphical slope field investigations. For a preview of the document as a pdf file, see the Slope Field Lab Preview.

Special TI-84Plus-only Programs (using the clock commands):

CLOCK is a ZIP file containing CLOCK.8XP, a circular 'analog' clock by Juan Gonzales and John Hanna. It displays a circular face with minute and hour hands and a sweeping dot for the seconds. Also display AM/PM and the date. Use the calculator's MODE to set the clock. Demonstrates the use of some clock functions and the importance of trigonometry in setting up the positions of the hands of the clock.

TIMER84 is a ZIP file containing TIMER84.8XP, a countdown timer. When you run the program, enter a number of seconds. Then the countdown begins. At the end, it displays "TIME'S UP!". A demonstration of the chkTimer() function built into the TI-84 and the 'length of a number' algorithm.

STOPWA01 contains a TI-84 Plus 'stopwatch' program that acts as a stopwatch using the clock functions. Press Enter to start and press Enter to stop and the elapsed time in seconds is displayed.

TI-83/4/Plus programs:

programs.zip contains programs.83g, programs.8xg, and programs.txt. You can explore the group files in Widoes if you have TI-Connect 1.6 installed or send the entire group file to a calculator without ungrouping. You can 'ungroup' the file to separate the programs in order to edit them (with the 'old' Graph-Link software) or send them individually to the calculator.

Opening the Black Box: LinReg Explained - (8 pages) My handout for the April, 2008 NCTM Annual Conference, Salt Lake City, Utah. This handout explains the mathematics of Linear Regression using the Least Squares Method in terms that high school Algebra students can grasp (with knowledge of parabolas). The document was produced with TI-Interactive! and the original TII file is available if you'd like it and there's also a TI-Nspire CAS version. Just contact me.

 TI83Symbols.zip (10/14/01- contains TI83Symbols.dot) The "TI-83P Symbols Template" for Word 2000, including a custom toolbar for the TI-83 keyfont symbols and a button linking to Grab83. Clicking the 'Grab83' button will paste a screenshot into the document using "Grab83". Put this file in your Templates folder. In Word, check Tools/Options and look at the File Locations tab to see where your template files are located. Naturally, you need to have the TI-83P Symbols font installed in order for these buttons to do their job. If you don't like the picture of the TI-83 in the left margin (it's really in the header!) , just double-click it and press the 'delete' key.

TI89Symbols.zip (new 03/04/01) is ZIPfile containing a Word2000 document template (TI89Symbols.dot) that contains a custom toolbar with some of the TI-89 keyfont characters as buttons. To use the .dot file, copy it to your c:\windows\Application Data\Microsoft\Templates folder. Then, either click your START button and choose "New Office Document", or, in Word, choose File/New... and you'll find TI89Symbols.dot as one of the 'General' document choices. Double-click it and you should get a new document with a TI-89 Symbols toolbar. To use the toolbar, just click one of the buttons and that symbol from the TI-89 Symbols font should appear at the current cursor position in the current font size. Cool. Check back regularly for updates to this file or add your own toolbar buttons using the 'Make Your Own Toolbar' instructions above.

Make your own toolbar   (new 03/04/01): a one-page explanation of creating Word2000 macros and a custom toolbar to make 'buttons ' representing the TI calculator keyfont symbols. Makes short work of putting the calculator key symbols into your handouts. It's how my symbols templates got made.

The 'big idea' is the Feigenbaum fractal described above, but the article didn't mention the fractal.

Grab It Quick! This handout describes using my Grab* programs rather than TI Connect software to get calculator screenshots into your computer application. It also describes creating and using Word macros, and other useful graphics tricks to transfer images between your calculator and your computer. See my IVIEW page or Talk TI Software page for downloading the Grab programs and IVIEW programs.
