Emeryville, Calif. (May 3, 2011)Key Curriculum Press announces the publication of Precalculus with Trigonometry, Third Edition, designed to engage high school students of all abilities and modalities and prepare them for success in calculus and beyond. Author Paul Foerster weaves 50 years of classroom experience and his engineering knowledge into every exercise, setting the stage for real-world mathematics problem solving. A new wrap-around Teacher’s Edition helps teachers plan their year, support all students and integrate technology.

Reaching Every Student
Key’s approach to Precalculus with Trigonometry, Third Edition – and every textbook – is to reach every student. Each chapter presents concepts graphically, algebraically, geometrically, and verbally to optimize learning. English language learners can use the online bilingual dictionary template to define terms in their primary language. Differentiating Instruction notes indicate where students might struggle with concepts or language, and provide ideas for helping students succeed. A new, appealing four-color design adds visual interest for all students.

Flexible Curriculum for Meeting State Standards
Precalculus with Trigonometry facilitates flexibility in the curriculum to help teachers meet state and district requirements. Trigonometry chapters have been moved to the end of the text. Teachers who prefer to mix Precalculus with Trigonometry – as in the second edition – can still do so. Teacher guides indicate which sections can be abbreviated or skipped if time is limited. Detailed teaching notes and examples support a lecture-based approach. Journal prompts, projects, computer-based activities, and web-based Dynamic Precalculus Explorations support an interactive approach.

Big-Picture Mathematics
Chapters are organized into four coherent units, promoting better understanding of mathematical relationships. Cumulative review sections at the end of each unit reinforce the connections. Problem sets incorporate new concepts, ideas and terms, as well as provide another opportunity for discovery learning rather than just a review. Explorations challenge students to think about the application of, and relationships between, mathematical topics – rather than accept the information as isolated facts. Cooperative groups are encouraged in Explorations, prompting students to explain their work and better articulate mathematical ideas and reasoning.

Incorporating Technology
Precalculus with Trigonometry thoroughly supports the use of technology. Online dynamic explorations, presentations and activities using The Geometer’s Sketchpad® and Fathom Dynamic Data™ software, as well as CAS (Computer Algebra Systems) provide in-depth exploration of concepts. Students use graphing calculators to visually explore functions, investigate real-world applications, and prepare for AP Calculus. Data sets and calculator programs for TI-83/84 Plus and TI-Nspire further engage students.

Functional Changes to Textbook Content
The content of Polynomial and Rational Functions, Limits and Derivatives has been split into two chapters. The study of rational functions and the analytic study of zeroes of functions are expanded and fall earlier in the text. The last chapter of the text focuses on introductory calculus topics. A new section was added to the study of conic sections, in order to separate the study of their Cartesian and parametric equations.

Precalculus with Trigonometry, Third Edition, was tested for readability using three commonly used readability formulas for secondary, grade-level material. The Dale-Chall Formula uses a list of familiar words in conjunction with the sample’s total number of words and sentences. The Flesch-Kincaid Formula uses the sample’s number of words, syllables and sentences. The Fry Formula is based on sentence length and number of syllables. Averaging the results for each test, Precalculus with Trigonometry scored 7.3, 7.1 and 7.9 (respectively), demonstrating that the textbook reading material is accessible to the majority of high school students.

More Support for Teachers
Teachers benefit from more than the new wrap-around Teacher’s Edition. Section Notes give extensive guidance for teaching each section. Problem Notes give background on the concepts behind many problems. A Solutions Manual includes step-by-step solutions for every problem. Technology Notes provide suggestions for incorporating Sketchpad, Fathom and calculator programs. On-page answers enable teachers to quickly check students’ answers. Reading analysis, journal entries and self-assessment tools help teachers insure student comprehension.
