## Description

**This package contains the Access Kit for the Trigsted/Bodden/Gallaher MyMathLab eCourse plus the eText Reference.**

**Developmental Mathematics** by Trigsted, Bodden, and Gallaher is the first online, completely “clickable” combined Prealgebra, Beginning Algebra, and Intermediate Algebra text to take full advantage of MyMathLab’s features and benefits. Kirk Trigsted saw marked improvements in student learning when he started teaching with MyMathLab, but he noticed that most students started their assignments by going directly to the MyMathLab homework exercises without consulting their textbook. This inspired Kirk to write a true eText, built within MyMathLab, to create a dynamic, seamless learning experience that would better meet the needs and expectations of his students. Completely clickable and fully integrated—the Trigsted eText is designed for today’s learners.

**Developmental Mathematics** is also available to be packaged with two printed resources to provide additional support for you:

- The
**eText Reference**is a spiral-bound, printed version of the eText that provides a place for you to do practice work and summarize key concepts from the online videos and animations. In addition to the benefits it provides you, the eText Reference is also a nice resource for those instructors that prefer a printed text for class preparation. - The
**Guided Notebook**is an interactive workbook that guides you through the course by asking you to write down key definitions and work through important examples for each section of the eText. This resource is available in a three-hole-punched, unbound format to provide the foundation for a personalized course notebook. You can integrate your class notes and homework notes within the appropriate section of the Guided Notebook. Instructors can customize the Guided Notebook files found within MyMathLab.
