    Second Wave Intervention to Support the Diocesan Numeracy Improvement Strategy

    Extending Mathematical Understanding (EMU) is a research-based intervention program developed by Dr Ann Gervasoni of ACU in association with the Early Numeracy Research Project (1999-2002), focusing on the early years of schooling.

    The EMU Program has been shown by detailed research to improve children’s learning and confidence with mathematics. 

    EMU is the Second Wave Intervention for Numeracy in the Diocese of Sale. As part of the Diocesan Numeracy Improvement Strategy, teachers have been trained as specialist intervention teachers who implement the EMU in their schools with targeted groups of children who have been identified as being at risk in their numeracy learning.

    EMU Models of Implementation

    The EMU Program involves intensive 30-minute daily sessions for groups of 3 children over a period of 10-20 weeks.



    Selection of EMU Students

    In selecting students to be part of EMU, schools should consider the following:

    Formation of Groups:

    • Each child being considered has been at school for twelve months
    • The children forming the group have a similar ENI profile (eg 2101)
    • Other Learning commitments of the student are considered (eg Reading Recovery)
    • Social considerations


    • An allocation of 0.3FTE would allow for 2 groups to form (1½ hours per day).
    • Schools with one Year 1 class should allow for at least one EMU group (10% students)
    • Each EMU session runs for ½ hour, 5 days a week


    Key People:

    • Carole Livesey,  trained EMU Professional Learning Leader and Education Officer (Second Wave Programs), will work closely with all EMU Specialist Teachers in the Diocese to ensure the authenticity of the program’s implementation.
    • Dr Ann Gervasoni (Australian Catholic University) is a Senior Lecturer in Education and founder of EMU.  She will oversee the implementation of EMU in the Diocese of Sale.
