9:30 a.m.–10:30 a.m.
438 New Approaches to the Fourth Year of High School Mathematics (9–12, Higher Education) Session Linear algebra can bring algebraic and geometric thinking together in ways that reinforce both. Participants will sample activities from a new, NSF-funded curriculum, drawing on vector algebra, geometry,and equations of lines and planes, and look at some of the rich applications of the subject.The only background required is second-year algebra. Kevin Waterman Education Development Center, Newton, Massachusetts Stephanie Ragucci Andover High School, Massachusetts 14 B (Convention Center)
439 Stimulating Interest in Statistics through the Use of Government Data (9–12, Higher Education) Session Much statistical information of interest to students’ daily lives are available on public Web sites maintained by federal statistical agencies.The speaker will show examples of this data, describe how to access it, and consider how to present it to stimulate students’ interest in statistics and encourage them to consider careers in public service. Ron Wasserstein American Statistical Association, Alexandria, Virginia 4 (Convention Center)
440 Unexpected Expectations (9–12, Higher Education) Session Mathematical expectation provides a means of quantifying the expected outcome of an experiment involving more than one possible outcome. This talk will present the quirkier (paradoxical) issues that can arise, including Newcomb’s paradox, Parrondo’s paradox, and the Prisoner’s Dilemma. Leonard Wapner El Camino College, Torrance, California 11 B (Convention Center)
441 The Pythagorean Theorem and Ptolemy’s Theorem (9–12, Higher Education) Session The speaker will look at the Pythagorean theorem again, and show the result using a less famous theorem in geometry called Ptolemy’s theorem. Geometry problems for the classroom will be shown. Gail Marie Nord Gonzaga University, Spokane, Washington Molly A/B (Hyatt)
442 Succeeding in Challenging Times: Where to Start and What Next (9–12, Preservice and In-Service) Session It’s probably not what you expected. Learn how to get ready; how to start; how to take the next steps to be successful; and how to finish the year. From working with challenging students to challenging students, from administrators to parents, look for ways to engage toward success.

443 A “Founders of Mathematics” Project: More than a Biographical Listing (Higher Education, Preservice and In-Service) Session Tired of student’s “cut and paste” papers? This Founders of Mathematics project requires insights from the student beyond summarizing. Students must estimate a founder’s worth to a particular field as well as predict what it will take for the student to become “famous” in the course being taken. A “recipe for success” will be available. Stephen LaVerne Brown Olivet Nazarene University, Bourbonnais, Illinois Douglas Pavilion B (Hyatt)
444 Response to Intervention (RtI) and Mathematics: Help for Struggling Students (Higher Education, Preservice and In-Service) Session The three-tiered RtI strategy will be discussed using examples of problem-solving instructional strategies that focus on teaching mathematics in context. Relevant research on RtI initiatives in mathematics, including technology resources, will be presented and synthesized into a take-home checklist. Dolores Burton New York Institute of Technology, Old Westbury 6 B (Convention Center)
