Students explore the TI-83/84 on their own by following the step-by-step instructions. This intro to the graphing calculator focuses on typing in common functions correctly and exploring how to use the GRAPH screen effectively Many of my students are intimidated by the many buttons of the TI-83/84, especially because it is so much less intuitive than their calculator apps on their phones. They've found this to be a very useful exercise and I have them keep it in the front of their binders.

Students use circular objects and string to derive the circumference formula and therefore define what a "radian" is. Students finish by finding a formula for conversion between radians and degrees and complete the Unit Circle in radians.

There's a steep learning curve for kids and the TI-83 or TI-84. Here are 5 common errors and 5 nifty tricks that will make things smoother! I split these up into 5 groups (1 common error and 1 nifty trick on each) so that students could either be put into groups or stations to learn each one. Then rotate or go out and teach each other what they learned. See also my lessons on teaching how to use the table, window, and regression formula on the TI-83/84.

This is a quick reference sheet I give my students so they don't have to stop class and ask me for help when they receive an ERROR message on their calculators. It shows the most common error messages that they run into during pre-calculus (WINDOW RANGE, INVALID DIM, DIM MISMATCH, SYNTAX) and how to solve it.
