Students must create functions based off commands. When they are graphed together (on paper and on a graphing calculator) they create an image of a grumpy old man. I use this activity before I have the students create their own image on Desmos.com. They say it is really helpful for them. Practices: - Function transformation with linear, absolute value, quadratic, square root, cubic, and cubed root functions. - Finding domain and range. - Finding key/anchor points. - Graphing with restricted

Students must use linear, absolute value, quadratic, square root, cubic, cubed root, and radical functions to create an image of their own. Practices: - Function Transformation - Domain and Range - Finding key/anchor points - Graphing with a restricted domain on paper and a calculator

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 explore the TI-84 on their own by following the step-by-step instructions. This intro to the graphing calculator focuses on using the TABLESET and WINDOW. 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. Check out my other TI-84-Help sheets.

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. 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
