**About this book**

**Experiencing Math in Context: **Rockswold/Krieger’s unique approach presents students with the math in context first, before explaining the abstract mathematical theory behind it. This gives students a familiar and concrete foundation to build the concepts on. Math in the context of the real world is emphasized throughout - both to engage students’ interest, and to help them grasp mathematical concepts through tangible applications.

**Connecting Concepts with Your Life **reinforces students’ knowledge needed to understand a new concept. The new Connecting Concepts with Your Life feature gives meaning to mathematics by relating common life experiences that students already understand**Math in Context **engages students by connecting mathematics to current and relevant topics. This new feature helps students recognize when and how math connects to everyday life**UPDATED! Applications **engage students by connecting mathematics to current and relevant topics. Several new examples have been added that discuss the mathematics of the Internet, social networking, tablet computers, and other contemporary topics**Modeling Data** in hundreds of exercises and examples offer students the chance to model real and relevant data with their own functions**Online Exploration** exercises invite students to find their own data on the Internet and use mathematics to analyze it.
