Abstract
Mathematics is abstract in the sense that mathematical concepts are formed by a process of
abstraction-the recognition and reification of a similarity between a set of previously
unrelated objects, events, or ideas. It follows that effective mathematics teaching should
promote the abstraction process. Traditional.m:ethods seldom do so. Constructivist methods
theoretically encourage abstraction, but this is rarely emphasised and the result may be an
inefficient teaching procedure. Three examples are given of how explicit attention to the
abstraction process could let'd to radically different approaches to· teaching; Some principles of
what we call Teaching for Abstraction are abstracted from these examples.
