The Graphing Calculator Manual by Judith A. Penna contains keystroke level instruction for the Texas Instruments TI-83/83+, TI-84, and TI-86. Bundled with every copy of the text, the Graphing Calculator Manual uses actual examples and exercises from Intermediate Algebra: Graphs and Models, Third Edition, to help teach students to use their graphing calculator. The order of topics in the Graphing Calculator Manual mirrors that of the text, providing a just-in-time mode of instruction.

The authors help students "see the math" through their focus on functions; visual emphasis; side-by-side algebraic and graphical solutions; real-data applications; and examples and exercises. By remaining focused on today's students and their needs, the authors lead students to mathematical understanding and, ultimately, success in class.
