Abstract
Understanding that mathematics is not just an arbitrary collection of rules to follow is basic to good mathematics learning, but studies show that many classrooms exhibit little mathematical reasoning. In order to better understand the nature of reasoning in schools, this study examined the modes of explicit reasoning in the explanations, justification and proofs of several topics in four textbooks. Eight distinct modes of reasoning are identified, illustrations of these are given, and their characteristics are discussed.
