In this paper, the authors argue that adult numeracy is a small educational field with little published research and only a small number of teaching materials and professional development and training packages available. Since the late 1980s, Australia has become quite active in the adult numeracy area and now has developed quite a range of adult numeracy curriculum, teaching resources and professional development options for teachers. This paper defines numeracy as more than mathematics and describes the establishment of the course, Adult Numeracy Teaching : Making Meaning in Mathematics (ANT), a professional development course targeted at experienced adult literacy, language and numeracy teachers.
