Interactive Developmental Mathematics, 2nd Edition enables you to experience math in context. It brings the proven Rockswold/Krieger approach into a digital experience made for the way students learn today. The authors believe that developing a mathematical concept in a tangible, applied context before explaining the abstract theory behind it helps you make math part of your own experiences in the world, and thus better understand it. This conceptual approach is delivered through Interactive Assignments, which provide bite-sized pieces of instruction with just-in-time trackable assessment. A 3-step learning path for each section guides you through a manageable to-do list: 1) Connect with the Math: Do the Interactive Assignment to learn skills and concepts. 2) Quiz Yourself: Take a quiz to test your understanding. 3) Do Your Homework: Do the personalized homework. The extensive video program, created entirely by the author team, is integrated throughout the Interactive Assignments to support visualization and understanding.
