Helping Students Innovatively "Do the Math"
The Sullivan Elementary & Intermediate Developmental Math Series, 4^{th} Edition introduces students to the logic, precision and rigor of mathematics, while building a foundation for success in future math courses.
Known for their hallmark examples that give students extra stepbystep support, the authors have continued their successful text pedagogy and have focused in the revision to translating it to the MyLab™ Math course for a truly dynamic learning and teaching experience. Key revisions to the MyLab Math course include guided “How To” exercises, modeled on the successful Show Case examples and new GeoGebra applet exercises.
The Sullivan team has revised their MyLab Math course to ensure that students are getting the most of the resources they have at their disposal. For example, they offer an enhanced etext that allows students to easily and quickly refer back to a specific page for examples. To encourage students outside of the classroom, the author team developed a MyLab Math that helps them develop good study skills, garner an understanding of the connections between topics, and work smarter in the process.
Also available with MyLab Math.
MyLab™ Math is an online homework, tutorial, and assessment program designed to work with this text to engage students and improve results. 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.
Students, if interested in purchasing this title with MyMathLab, ask your instructor for the correct package ISBN and Course ID. Instructors, contact your Pearson representative for more information.
