INTERMEDIATE ALGEBRA: CONNECTING CONCEPTS THROUGH APPLICATIONS shows students how to apply traditional mathematical skills in real-world contexts. The emphasis on skill building and applications engages students as they master concepts, problem solving, and communication skills. It modifies the rule of four, integrating algebraic techniques, graphing, the use of data in tables, and writing sentences to communicate solutions to application problems. The authors have developed several key ideas to make concepts real and vivid for students. First, the authors integrate applications, drawing on real-world data to show students why they need to know and how to apply math. The applications help students develop the skills needed to explain the meaning of answers in the context of the application. Second, they emphasize strong algebra skills. These skills support the applications and enhance student comprehension. Third, the authors use an eyeball best-fit approach to modeling. Doing models by hand helps students focus on the characteristics of each function type. Fourth, the text underscores the importance of graphs and graphing. Students learn graphing by hand, while the graphing calculator is used to display real-life data problems. In short, INTERMEDIATE ALGEBRA: CONNECTING CONCEPTS THROUGH APPLICATIONS takes an application-driven approach to algebra, using appropriate calculator

  • An Innovative Critical-Thinking Feature: Concept Investigations. The directed-discovery activities called Concept Investigations are ideal as group work during class, incorporated as part of a lecture, or as individual assignments to investigate concepts further. Inserted at key points within the chapter, each Concept Investigation helps students explore patterns and relationships such as the graphical and algebraic representations of the functions being studied.
  • Extensive End-of-Chapter Material. Includes Chapter Summaries, Review Exercises, Chapter Tests, Chapter Projects, Equation Solving Toolbox, and Cumulative Reviews. Chapter Summaries revisit the big ideas of the chapter and reinforce them with new worked-out examples. Students can also review and practice what they have learned with the Chapter Review exercises before taking the Chapter Test.
  • Chapter Projects. To enhance critical thinking, end-of-chapter projects can be assigned either individually or as group work. Instructors can choose which projects best suit the focus of their class and give their students the chance to show how well they can tie together the concepts they have learned in that chapter. Some of these projects include online research or activities that students must perform to analyze data and make conclusions.
  • Equation Solving Toolbox. This feature appears after every two chapters and revisits and summarizes skills students have used to solve equations in preceding chapters and processes for finding models.
  • Cumulative Reviews. Cumulative reviews appear after every two chapters, and group together the major topics across chapters. Answers to all the exercises are available to students in the answer appendix.
  • Worked Examples with In-Text Practice Problems. This text offers a comprehensive range of examples from basic techniques (solving by hand, exponent rules, graphing) to realistic applications with manageable data sets to intriguing applications that call for critical thinking about phenomena (population growth) and daily activities (interest rates in action, the cost of a truck rental). Worked examples are labeled so students can make the connection between the example and the concept being studied. The accompanying in-text practice problems help students to gain a sense of a concept through an example and then to practice what has been taught in the preceding discussion. In addition, examples of hand-drawn graphs help students visualize what their own work should look like.
  • Practical Help for Instructors. Practical tips are provided in the Annotated Instructor's Edition on how to approach and pace chapters as well as integrate features such as Concept Investigations. In addition, for every student example in the student text, there is a different instructor classroom example in the AIE, with accompanying answers that can be used for additional in-class practice and/or homework.
  • Integrated "Student" Work. Clearly identifiable examples of "student" work appear throughout the text in Examples and Exercises. These boxes ask students to find and correct common errors in "student" work.
  • An Eyeball Best-Fit Approach. Linear, quadratic, and exponential functions are analyzed through modeling data using an eyeball best-fit approach. These models investigate questions in the context of real-life situations. Creating models by hand leads students to analyze more carefully the parts of each function reinforcing solving techniques and making a better connection to the real-life data and how they affect the attributes of the function's graph. Graphing calculators are used to plot data and check the fit of each model.
  • Margin Notes. The margin contains four kinds of notes written to help the student with specific types of information: Skill Connections provide a just-in-time review of core mathematical concepts, reinforcing student skill sets; Connecting the Concepts reinforce a concept by showing relationships across sections; Specific vocabulary of mathematics and the applications are helpfully defined and reinforced through margin notes called "What's That Mean?"; and Using Your TI-Graphing Calculator offers just-in-time calculator tips for students. Additional material is available in the Using the Graphing Calculator Appendix.
  • Exercise Sets. The exercise sets include a balance of both applications and skill-based problems developed with a clear level of progression in terms of difficulty level. Most exercise sets begin with a few warm-up problems before focusing on applications. Exercise sets typically end with additional skill practice to help students master the concepts when needed. A balance of graphical, numerical, and algebraic skill problems is included throughout the book to help students see mathematics from several different views. End-of-book answers are written in full sentences to underscore the emphasis on student communication skills.
  • Enhanced WebAssign, used by over one million students at more than 1,100 institutions, allows you to assign, collect, grade, and record homework assignments via the Web. This proven and reliable homework system includes thousands of algorithmically generated homework problems, links to relevant textbook sections, video examples, problem-specific tutorials, and more. New Assignable Stand Alone Master It questions are unique to INTERMEDIATE ALGEBRA, and reinforce student understanding and develop conceptual knowledge. These modeling type problems contain real-life data, break the question into multiple parts, and reflect the step-by-step process that is taught in the text. These problems support the conceptual and applied approach of the textbook and force students to confirm their understanding as they work through each step of the problem.
  • Appropriate Use of the Calculator. Graphing calculators are used in this text to help students understand mathematical concepts and to work with real-world data. Graphing calculators are used to create scatterplots of real data and to check the reasonableness of algebraic models for the data. Linear, quadratic, and exponential models are created by hand, using an eyeball best-fit approach and algebraic techniques. The calculator is also used to check solutions both graphically and numerically and to do some numerical calculations. However, students are also required to solve problems, graph, and do other algebraic skills by hand.
