In this paper, the specific concerns for literacy and numeracy as we enter a new era are addressed through a discussion of an innovative mathematics early intervention program, which the author and classroom teachers have developed and applied. 'Mathematics Intervention' is an innovative program developed by three classroom teachers to identify, then assist, children in year 1 'at risk' of not coping with the current mathematics curriculum. The program incorporates assessment tools and learning activities based on recent research about children's early numerical learning. It develops the basic concepts of number upon which children build their understanding of mathematics. All three teachers participated in a professional development course, which developed skills that allow teachers to recognise which children have a problem, to identify the underlying problem and to provide appropriate activities to advance their mathematical development. The course highlights the benefits of clinical interviewing as an assessment tool and promotes various strategies that classroom teachers can use to assist the development of numerical concepts. 'Mathematics Intervention' is an example of a programme developed and implemented by classroom teachers using new learning processes designed to empower classroom teachers to meet the challenge of advancing all children's mathematical development.
