*This text provides a one-semester alternative to the traditional two-semester developmental algebra sequence for non-STEM (Science, Technology, Engineering, and Math) students. This new approach offers an accelerated pathway to college readiness through developmental math, preparing non-STEM students to move directly into liberal arts math or introductory statistics, while also preparing STEM students for intermediate algebra.*

**An Accelerated Pathway through Developmental Math**

**Math Lit**, by Kathleen Almy and Heather Foes, offers an accelerated pathway through developmental math, allowing non-STEM students to move directly into liberal arts math or introductory statistics. Through its emphasis on contextual problem solving, the Almy/Foes text and its accompanying MyMathLab® course help students gain the mathematical maturity necessary to be successful in a college-level non-STEM math class. Students work through carefully designed explorations, activities, and instruction to garner a greater conceptual understanding of the major themes of numeracy, proportional reasoning, algebraic reasoning, and functions. Enhancements in the Second Edition have increased the versatility and ease of use for students and instructors alike.
