*For courses in developmental mathematics.*

**Giving Meaning to the Numbers**

**Gary Rockswold and Terry Krieger** give meaning to the numbers that students encounter by *developing concepts in context *through the use of applications, multiple representations, and visualization. By seeing the concept in context *before* being given the mathematical abstraction, students make math part of their own experiences instead of just memorizing techniques. Research is showing that this method is essential to empowering students. Seamlessly integrated real-life connections, graphs, tables, charts, and meaningful data help students deepen understanding and prepare for future math courses—and life—by teaching them critical thinking and problem-solving skills.

**Built in MyMathLab**

** Interactive Developmental Mathematics ** offers a completely digital experience, built by Gary Rockswold and Terry Krieger from the ground up in MyMathLab to model the way today’s students learn and interact online. MyMathLab is an online homework, tutorial, and assessment program designed to engage students and lead them to master the concepts and skills they need to succeed in math. Within its guided learning environment, students practice what they learn, test their understanding, and pursue a personalized study plan that helps them master course material and understand difficult concepts.

**Gary Rockswold** has been a professor and teacher of mathematics, computer science, astronomy, and physical science for over 35 years. He has taught not only at the undergraduate and graduate college levels, but he has also taught middle school, high school, vocational school, and adult education. He received his BA degree with majors in mathematics and physics from St. Olaf College and his Ph.D. in applied mathematics from Iowa State University. He has been a principal investigator at the Minnesota Supercomputer Institute, publishing research articles in numerical analysis and parallel processing and is currently an emeritus professor of mathematics at Minnesota State University, Mankato. He is an author for Pearson Education and has over 10 current textbooks at the developmental and precalculus levels. His developmental coauthor and friend is Terry Krieger. They have been working together for over two decades. Making mathematics meaningful for students and professing the power of mathematics are special passions for Gary.
