Developmental Mathematics with Applications and Visualization: Prealgebra, Beginning Algebra, and Intermediate Algebra, 2nd edition

For courses in Prealgebra & Beginning Algebra.

The Rockswold/Krieger algebra series fosters conceptual understanding by developing concepts in context through the use of applications, multiple representations, and visualization. By seeing the concept in context before being given the the mathematical abstraction, students make math part of their own experiences instead of just memorizing techniques. The authors believe this approach deepens conceptual understanding and better prepares students for future math courses and life. The new edition continues to bring concepts to life with even more opportunities for students to visualize the math in real-world contexts -- and so, learn key critical-thinking and problem-solving skills -- with new features in the text and MyLab^™ Math.

Within its structured environment, students practice what they learn, test their understanding, and pursue a personalized study plan that helps them absorb course material and understand difficult concepts. The 2nd Edition continues to help students develop conceptual understanding and bring key concepts to life with content and assignments that reflect the authors’ approach, including new Section Introduction videos and See the Concept videos with assessment. New Skill Builder assignments offer adaptive practice to build students’ foundational skills, and new workspace assignments allow students to show their mathematical reasoning as they progress step-by-step, with specific feedback at each step in the problem-solving process that adjusts to their path.  

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.

• NEW! 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.
• NEW! 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.
• NEW! Modeling Data in hundreds of exercises and examples offer students the chance to model real and relevant data with their own functions.
• NEW! Online Exploration exercises invite students to find their own data on the Internet and use mathematics to analyze it.            
• Chapter Openers start each chapter with a contemporary application that motivates students by offering insights into the relevance of that chapter’s mathematical concepts.

Understanding and Visualizing the Concepts: The Rockswold/Krieger approach excels at promoting conceptual understanding above procedural skills. Additionally, an emphasis on visualization provides opportunities for students with different learning styles to successfully absorb the information presented.

• NEW! See the Concept presents a concise, visual overview of topics that were previously written out as text. Visualizing the math makes it accessible to all students. Companion See the Concept videos in MyLab Math, presented by the authors, help bring the concept to life. Each See the Concept video also has accompanying MyLab Math assessment questions, making these videos truly assignable .
• Putting It All Together boxes at the end of each section summarize techniques and reinforce the mathematical concepts presented in the section and are also available to be assigned in MyLab Math.
• NEW! Comment Balloons appear next to steps and procedures to make them more (immediately) understandable.
• Learning the Math from Multiple Perspectives presents concepts by means of verbal, graphical, numerical, and symbolic representations to support multiple learning styles and problem-solving methods.
• New Vocabulary is listed at the start of every section, highlighting the math concepts that are introduced in that section. This gives students a glimpse of the big picture of the section and helps with test preparation.
• Reading Check questions appear alongside important concepts, ensuring that students understand the material they have just read. These are located throughout every section. Many Reading Checks are assignable in MyLab Math.
• Making Connections occur throughout the text and help students see how previous concepts are related to new concepts. Many Making Connections exercises are assignable in MyLab Math.
• Critical Thinking exercises are included in most sections, posing questions that can be used for class discussion, group work, or homework assignments. Selected Critical Thinking features are also available to be assigned in MyLab Math.
• NEW! Guided Workbook is keyed to the text by section and objective and leads students through the course, giving them the opportunity to record key information, work practice problems, and show and keep their work for reference—as well as taking conceptual understanding one step further by asking students to explain Why? after select questions.

Practicing and Mastering the Concepts: Ample opportunity for students to practice and review the concepts and skills ensures students retain what they’ve learned.                

• Now Try exercises follow every example for immediate reinforcement of the skills and concepts.
• NEW! Objective Lists at the beginning of each section give a clear outline of the section contents, making it easier to customize the course.               
• Concepts and Vocabulary exercises appear in every section. 
• Checking Basic Concepts exercises appear after every other section and can be used for individual or group review. These exercises require 10–20 minutes to complete and are also appropriate for in-class work. 
• Thinking Generally encourage students to synthesize what they have just learned with open-ended conceptual questions that appear in most section exercise sets.                                           
• Writing about Mathematics exercises appear at the end of most sections. Students are asked to explain the concepts behind the mathematical procedures they just learned in their own words, encouraging true understanding instead of simple rote memorization.                             
• Group Activities appear once or twice per chapter and provide an opportunity for students to work collaboratively on a problem that involves real-world data. Most activities can be completed with limited use of class time.                         
• Using a Graphing Calculator                                                                                 
• Graphing Calculator Exercise icons denote an optional exercise that requires students to have access to a graphing calculator.
• Technology Notes throughout the text are optional notes that offer students guidance, suggestions, and caution.
• Study Tips offer just-in-time suggestions to help students stay organized and focused on the material at hand.
• Chapter Summary combines key terms, topics, and procedures with illuminating examples to assist students as they prepare for the test with a quick but thorough review.
• Chapter Review Exercises requires students to work exercises and gain confidence while mastering the material.
• Chapter Tests provide students with rehearsal for the real thing and help reduce math anxiety. 
• Chapter Test Prep Videos offer additional help by showing an instructor working through the step-by-step solutions to every exercise in each Chapter Test.
• Cumulative Review Exercises Starting with Chapter 2 and appearing in all subsequent chapters, Cumulative Review Exercises help students see the big picture of math by reviewing topics and skills they have already learned.
