Beginning Algebra with Applications

Designed for the first-year developmental math course in beginning algebra, this text retains the hallmark features that have given the Aufmann texts a solid reputation for reliability: a clear writing style, an emphasis on problem-solving strategies, and the acclaimed Aufmann Interactive Method. The text's objective-based framework offers guided learning for both lecture and self-paced courses. The IAE, rich with instructor support materials, features reduced student pages with support material in the margins. (Answers to exercises and transparency icons appear on the reduced student page.) Features include Instructor Notes; tips for introducing new or recycled vocabulary, symbols, formulas, rules, properties or equations;Discuss the Conceptsprompts;Concept Checkquestions;Optional Student Activities; In-Class Examplesto present with every objective;Suggested Assignments; Quick Quiz;and Answers to selectedWriting Exercises, Focus on Problem Solvingactivities, andProjects and Group Activities. AIM for Success,a special preface for students, guides them in how to be successful using the text and the Aufmann Interactive Method (AIM). Suggestions for using the Preface as a lesson are featured in the Instructor's Resource Manual. Eduspace, powered by Blackboard, for the Aufmann/Barker/LockwoodBeginning Algebracourse includes algorithmic exercises, an online Study Guide and test bank content in question pools.
