--> Foreword: Mathematics for a Modern Age ZELL MILLER Governor of Georgia Now more than ever, our daily lives are directly affected by mathematics. I'm not just talking about the grades students get or how many mathematics classes they have to take. I'm talking about answering the phone, faxing a document, or driving a car. I'm talking about buying medicine for your family, building a house, and listening to music. Mathematics has also helped bring us things that indirectly affect us, like the discoveries of DNA, weather patterns, and how to use light as a surgical tool. It has helped us walk on the moon, create microchips, and transmit images across thousands of miles. With mathematics, we design models to test our ideas and refine them, from nerve impulses to human behavior, volcanoes to food. Mathematics is everywhere. But mathematics has always been around, and the concepts it uses have always helped us. So why is mathematics so much more important to our lives now than it was then? Years ago, in the eras of the abacus or slide rule, information took a lot longer to sort through, but now it is easy to chart a course, assay a risk, or compare statistics. Information is more abundant than ever. You can find answers about everything from world politics to school lunches almost as soon as you think of the questions. This new speed of access to volumes of information obviously brings good

--> things—like better medical information, better building materials, and more diverse options in business and education. The down side to all of this is that as easily as there can be information, there can be misuse of information. So what does this mean for our children? More than ever, they need to be mathematically savvy. Learning to think and reason mathematically is the only way our children can be sure that they are in control, not being controlled. More practically, almost every job these days requires at least some elementary understanding of mathematics. In fact, many of the jobs that keep our country competitive and successful in the global market are jobs that require more than basic mathematics comprehension. Not that everyone needs to be able to program a computer or predict the stock market, but with the vastly increased speed of statistical calculation (and manipulation) and easier and faster global communication, our children need to know what a number means, where it came from, and how best to judge its veracity. As the Governor of Georgia, I take all of this pretty seriously. I know the importance of bringing businesses to my state to create jobs for Georgians. The world, however, is their marketplace; to be healthy, competitive, and economically secure, our citizens must understand mathematics. They need to become comfortable with the notion of mathematics as a tool for life. GOVERNOR ZELL MILLER was elected Governor of the state of Georgia in 1990. Since taking office, his love of teaching and commitment to education has resulted in one of the most ambitious agendas to improve public education in this century. Governor Miller's public career includes service at virtually every level of government: as mayor, as a member of the state senate, as lieutenant governor, and now as Governor. He is currently Chairman of the Education Commission of the States. He has also chaired the Southern Governors' Association, the Appalachian Regional Commission, and the Council of State Governments. Governor Miller keynoted the 1992 Democratic National Convention in New York and chaired the Platform Drafting Committee for the 1996 Democratic National Convention in Chicago.

--> Acknowledgments For over ten years the Mathematical Sciences Education Board (MSEB) has worked to support the improvement of mathematics education. The work of the Board becomes visible largely through publications, beginning with Everybody Counts (1989) and Reshaping School Mathematics (1990). High School Mathematics at Work builds on this prior work. Like Measuring Up (1992), it contains student tasks; like Mathematical Preparation of the Technical Work Force (1995), it highlights the mathematics needed for careers. High School Mathematics at Work was developed through the efforts of more people than can be named individually here. We gratefully acknowledge the generous financial support of the Pew Charitable Trusts, and thank both Robert Schwartz for his special encouragement with this project when he was Director of their Education Programs, as well as Janet Kroll for her continuing interest and support as our program officer. The project was launched as a 12th grade sequel to Measuring Up through the initiative of Linda P. Rosen. The MSEB first envisioned that this sequel would illuminate some features of high-quality high school mathematics teaching and learning through standards-based assessment tasks. The growing interest in school-to-work issues, however, led to our giving this theme major prominence. With this new focus, Lynn Arthur Steen and Susan Forman designed the

--> project, secured funding, collected mathematical examples, commissioned essays, and worked with the Task Force, first as members of the MSEB staff and later as consultants. We also thank Daniel Goroff for his leadership during a period of staff transition. Examples of mathematical tasks were solicited over a period of two years from a wide variety of sources, as described in Appendix A. From the hundreds of examples that were contributed, the Task Force selected about two dozen for inclusion, wrote first drafts of those mathematical examples, and identified essay topics and authors. The resulting collection of examples and essays was molded into its current form by Bradford Findell, serving as editor, under the guidance of Glenda Lappan, Alan Schoenfeld, and Harvey Keynes, with the assistance of Cathy Kessel, and with substantial input from Deborah Ball, Sadie Bragg, Gail Burrill, Shari Coston, Shelley Ferguson, Melvin George, Rick Jennings, Jim Leitzel, Tony Martinez, Pamela Matthews, Patrick McCray, and Jack Price. Of course, no project of this size could ever come to completion without the contributions of support staff. Thanks especially to Sharon O'Donnell for her help collecting the essays and examples and to Catherine Bell and Doug Sprunger for their help with the review process. We must also thank Sally Stanfield, Linda Humphrey, and the staff at the National Academy Press for their support and patience with the complex evolution of this project.
