In how many ways can an integer be written as the sum of four squares? What's the probability that an integer picked at random has no perfect square factor? What's the probability that two integers picked at random have no common factor? Which linear functions f(x) = ax + b (a and b integers) generate infinitely many prime numbers for integer values of x? What is the probability that an integer picked at random between 1 and 1020 is a prime number? The real goal of the course is to answer the following question: How are all of the above questions related? In this three week course, you will investigate questions like those above and develop underlying structural similarities among them. In particular, you will see how to use the algebra of sequences and series as a general- purpose tool for these investigations. No prior knowledge of number theory or sequences and series is assumed, and by the end of three weeks, you'll be astounded at what you've discovered about arithmetic and its applications to the 7-12 curriculum. Reflecting on Practice: Connections to Research (1 hour per day, 5 days per week, plus opportunities for informal sessions in late afternoon and evenings) Participants will consider research related to teaching and learning mathematics with a particular focus on student thinking and questions designed to provoke student thinking. The discussion will be grounded in the study of discourse in lessons and classroom practice in both the United States and other countries. Participants will work collaboratively to consider different approaches to questioning that better enable students to learn mathematics.       download: Reading prior to Week 1 [username/password required]   Working Groups (2 hours, 4 days a week) As part of their summer activities, each participant selected for the 2009 Secondary School Teacher Summer Program will be assigned to a small subject-specific Working Group, which will prepare an activity or resource for the profession (with the associated mathematics) for piloting during the following year. The working groups are: Reasoning from Data and Chance Exploring Discrete Mathematics Investigating Geometry Learning from Teaching Cases Implementing Lesson Study Visualizing Functions Algebraic Number Theory
