Mathematics in Action (6^th Ed.)
Algebraic, Graphical, and Trigonometric Problem Solving

For courses in Intermediate Algebra.

Active learning for active minds

The authors of the Mathematics in Action series believe that students learn mathematics best by actually doing the math within a realistic context. If a student is taking this course, why teach them the same content in the same way that they?ve already seen?yet did not retain? Following this principle, the authors provide a series of guided-discovery activities that help students to construct, reflect upon, and apply mathematical concepts, deepening their conceptual understanding as they do so. The active style of learning develops critical-thinking skills and mathematical literacy, while keeping the concepts in the context of real applications.

The 6th Edition includes updated examples and activities for maximum interest and relevance, along with new and enhanced digital resources in MyLabTM Math to support conceptual understanding for students, wherever and whenever they need it.

About our authors

The Consortium for Foundation Mathematics is a group of mathematics educators, all originally from New York State, who first came together at SUNY Oswego in the summer of 1995 as part of a National Science Foundation (NSF) grant. The members of the group represented 2-year and 4-year colleges, commuter and residential colleges, large urban institutions and small rural institutions, and multi-campus as well as single-campus institutions.

Unified by a desire to change the status quo to further student success, the group’s initial objectives aimed at a new approach to developmental math that included contextual problem-solving, active collaborative learning, and authentic assessment tied more closely to real-world skills. The efforts of this initial grant resulted in new instructional materials that formed the basis of Consortium’s texts, which include range from Prealgebra to Intermediate Algebra, as well as high school titles. As one Consortium author noted, contributing to this series with its different approach “changed my views about math, and about teaching math.” Of the 16 instructors originally involved in the grant, 8 instructors contribute to the latest editions of the text.
