This article presents the first part of the closing address given by the author to the 2007 Association of Teachers of Mathematics (ATM) Easter conference at Loughborough. In his closing address, the author focuses on functioning mathematically as opposed to functional mathematics. His view of functional mathematics is that the focus is on someone else's content and its external purposes. On the other hand, his view of functioning mathematically is that the focus is on processes and internal awarenesses. The following are the processes of learning: (1) deciding what to do, how to do it; (2) deciding how to work; (3) doing it; (4) interpreting what they have done; (5) communicating what they have done; (6) evaluating what they have done; and (7) mathematical appreciation.
