# Developmental Mathematics

by D. Franklin Wright

Providing a smooth transition between arithmetic and algebra, Developmental Mathematics emphasizes reasoning, problem solving, and connections between arithmetic and algebraic concepts.

The second edition includes new features, such as Strategies for Academic Success, which help students with soft skills like note taking, time management, and the ability to overcome test anxiety; Concept Checks, which test students’ understanding of important definitions and concepts in each section; and additional real-world application problems. Bundle the textbook and software with Guided Notes, a binder-ready supplement that provides further direction and student engagement.
