# Quantitative Reasoning: Tools for Today's Informed Citizen

For Instructors
The need for quantitative reasoning courses has never been stronger: Citing a recent study funded by the Pew Charitable Trusts, the Associated Press reported in 2006 that more than half of the nation’s students at four-year colleges and universities “lack the literacy to handle complex, real-life tasks” such as understanding credit card offers, balancing checkbooks, and computing restaurant tips.

Quantitative Reasoning: Tools for Today’s Informed Citizen helps students connect mathematics in the classroom with applications in the real world. Through a series of hands-on activities and explorations, the text empowers students by teaching them to apply quantitative reasoning skills to make informed decisions in their daily lives. Authors Alicia Sevilla and Kay Somers developed this engaging, activity-based text for students enrolled in an introductory-level, problem-based general education quantitative reasoning course.  Technology is an essential component of the text, and it is integrated in Activities that use Microsoft® Excel or, alternatively, the TI-83/84 Plus graphing calculator. The use of technology helps students concentrate on ideas rather than computational details—allowing them to investigate significant and more realistic problems.
