The Rockswold/Krieger algebra series fosters conceptual understanding by using relevant applications and visualization to show students why math matters‎.‎ It answers the common question ‎"‎When will I ever use this‎?‎‎"‎ Rockswold teaches students the math in context‎,‎ rather than including the applications at the end of the presentation‎.‎ By seamlessly integrating meaningful applications that include real data and supporting visuals ‎(‎graphs‎,‎ tables‎,‎ charts‎,‎ colors‎,‎ and diagrams‎)‎‎,‎ students are able to see how math impacts their lives as they learn the concepts‎.‎ The authors believe this approach deepens conceptual understanding and better prepares students for future math courses and life‎.‎
