Features Written and refined over 10 years of teaching undergraduate students, K-12 teachers, and talented high-school students. I have endeavored to give clear proofs with almost 500 crisp illustrations, concise exposition and examples, and scholarship reflecting the state of the art in mathematics and its history. Examination and desk copies available from the AMS. Table of contents »

Resources Sample syllabi, quizzes, student project ideas, and more. Eventually I plan to provide resources for teaching number theory here. If you're teaching computational aspects of number theory, you may be interested in the Python programming notebooks below. If you would like to share your teaching materials, feel free to send me a note at weissman AT ucsc DOT edu.
