## Overview

BEGINNING 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 algebraic concepts, problem solving, and communication skills. Students learn how to solve problems generated from realistic applications, instead of learning techniques without conceptual understanding. The authors have developed several key ideas to make concepts real and vivid for students. First, they emphasize strong algebra skills. These skills support the applications and enhance student comprehension. Second, the authors integrate applications, drawing on realistic 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. Third, the authors develop key concepts as students progress through the course. For example, the distributive property is introduced in real numbers, covered when students are learning how to multiply a polynomial by a constant, and finally when students learn how to multiply a polynomial by a monomial. These concepts are reinforced through applications in the text. Last, the authors' approach prepares students for intermediate algebra by including an introduction to material such as functions and interval notation as well as the last chapter that covers linear and quadratic modeling.

- Prealgebra Review. The text begins in Chapter R by reviewing some prealgebra concepts, providing students with a review of those topics most necessary for beginning algebra such as arithmetic with signed numbers, fractions, decimals and percents. This chapter also reviews other traditional student weak spots--absolute value, the idea of opposites, and the order-of-operations agreement, ending with coverage of the real number system.
- 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.
- 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.
- 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.
- 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 concepts being studied.
- Worked Examples with In-Text Practice Problems. This text provides a broad range of examples that give students more practical experience with mathematics. Other examples reinforce patterns of problem solving by using a step-by-step approach, breaking down an example into more basic concepts or techniques and then following it immediately with a practice problem that is similar to that example.
- Integrated "Student" Work. Clearly identifiable examples of "student" work appear throughout the exercises in the text. These boxes ask students to find and correct common errors in "student" work.
- Margin Notes. The margin contains three 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; and specific vocabulary of mathematics and the applications are helpfully defined and reinforced through margin notes called "What's That Mean?"
- Reinforcement of Visual Learning through Graphs and Tables. Graphs and tables are used throughout the book to organize data, examine trends, and have students gain knowledge of graphing linear and quadratic equations. The graphical and numeric approach helps support visual learners, incorporating realistic situations into the text and reinforcing the graphs and data that students see in their daily lives.
- 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. Some 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.
- Flexible Use of the Calculator. The core exercises do not require calculator usage, although the book has been written to support the use of a scientific calculator. Calculator Details Margin boxes will appear as necessary to instruct students on the correct use of a scientific calculator. In certain Concept Investigations, the calculator is used to help students with arithmetic so that they may concentrate on looking for patterns. In selected applications, the calculator is used to do the numerical computations so that students can work with more realistic problem situations.
- Extensive End-of-Chapter Material includes Chapter Summaries, Review Exercises, Chapter Tests, Chapter Projects, 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.
