**Elayn Martin-Gay** firmly believes that every student can succeed, and her developmental math textbooks and video resources are motivated by this belief. **Prealgebra, Sixth Edition** was written to help readers effectively make the transition from arithmetic to algebra.

**Martin-Gay**’s emphasis on **Study Skills** ensures that students make the most of their valuable study time in order to help them succeed in this course. **Student Resources**, located in the back of the text, gives students a variety of tools that are conveniently located in one place to help them achieve success in math.

The new edition offers new resources like the **Student Organizer** (available separately) and now includes **Student Resources** in the back of the book to help students on their quest for success.

An award-winning instructor and best-selling author, **Elayn Martin-Gay** has taught mathematics at the University of New Orleans for more than 25 years. Her numerous teaching awards include the local University Alumni Association’s Award for *Excellence in Teaching*, and *Outstanding Developmental Educator* at University of New Orleans, presented by the Louisiana Association of Developmental Educators.

Prior to writing textbooks, Elayn developed an acclaimed series of lecture videos to support developmental mathematics students in their quest for success. These highly successful videos originally served as the foundation material for her texts. Today, the videos are specific to each book in the Martin-Gay series. Elayn also pioneered the **Chapter Test Prep Video** to help students as they prepare for a test–their most “teachable moment!”

Elayn’s experience has made her aware of how busy instructors are and what a difference quality support makes. For this reason, she created the **Instructor-to-Instructor** video series. These videos provide instructors with suggestions for presenting specific math topics and concepts in basic mathematics, prealgebra, beginning algebra, and intermediate algebra. Seasoned instructors can use them as a source for alternate approaches in the classroom. New or adjunct faculty may find the CDs useful for review.

Her textbooks and acclaimed video program support Elayn's passion of helping
