Show students how to apply traditional mathematical skills in real-world contexts with BEGINNING ALGEBRA: CONNECTING CONCEPTS THROUGH APPLICATIONS, 2nd Edition. Concepts become real and vivid as the authors draw from real data to show students why and how to apply math. Through conceptual explorations, skill building and applications, this text's approach helps students master concepts, and develop problem solving and communication skills. The authors integrate algebraic techniques, graphing, the use of data in tables, and writing sentences to communicate solutions to application problems. Strong algebra skills support applications while completing models by hand helps students focus on the characteristics of each function type. Accompanied by WebAssign, your students will be able to continue their conceptual experience while completing their online homework. Conceptual questions from the text are included and "WatchIts" with closed-captioning gives students another opportunity to both learn and practice skills and concepts through the power of WebAssign.
