## TI Graphing Calculator Tutorials

## Created by: Sue Glascoe (Mesa Community College Math dept)

These three tutorials were originally designed to be used during the first two weeks of my Brief Calculus classes (MAT 212) to make sure all students understood how to effectively use their graphing calculator. Each topic has four separate handouts which outline the specific steps for the individual calculator type (with screen snapshots). The files are in pdf format and can be viewed using Adobe Acrobat Reader..

## TOPIC |
## CALCULATOR TYPES |

## Evaluating Expressions |
||||

This handout is designed
to teach the process of evaluating a function for a given input (domain) value on a
graphing calculator. The methods taught involve using the homescreen to do arithmetic, using a table, using the "value" option for a graph, and using function notation. |

## Solving Equations |
||||

This handout is
designed to teach the process of solving an equation (given an output/range value, find
the input/domain value) on a graphing calculator. The methods taught involve using two graphs and finding their intersection(s), using one graph and finding the x-intercept(s), using a table to find solutions, and using the solver in the graphing calculator. |

## Linear Regression |
||||

This handout is designed to teach students to align given data sets, create lists on the calculator, view a scatter plot, perform a linear regression, store the regression equation, graph it, and use the equation to predict values on the graphing calculator. | TI-82 | TI-83 | TI-85 | TI-86 |

## Group Projects |
||||

These projects are to be used by the students in groups of 3 or 4, after they have completed the related handout. They are designed to check their understanding of the calculator methods and to help reinforce student interaction in a learning environment. | Evaluating Expressions | |||
