Getting Ready in Numeracy (GRIN) - Mathematics Intervention

The GRIN Intervention Program is a professional learning program for mathematics teachers and tutors. It aims to address difficulties that students experience when learning mathematics. The program targets students in primary and secondary schools.

Outcomes and successes

GRIN Intervention has been extraordinarily successful:

Support for the program

GRIN has already been introduced in primary and secondary schools across Victoria. It has been well received by

  • regional networks
  • principals
  • teachers
  • students.

How does GRIN work?

Trained tutors conduct GRIN sessions with small groups of students (ideally three), before the normal daily mathematics lesson. GRIN sessions are brief and focused - normally 15 to 25 minutes long.

GRIN sessions conducted by trained tutors will:

  • prepare intervention students for their subsequent mathematics lesson
  • familiarise students with the relevant language and terminology that they will hear during the classroom lesson
  • model what students can expect to see and/or do in the lesson.

Implementation in schools

The GRIN tutor can be a

  • teacher
  • numeracy coach
  • leading teacher
  • integration aide

- see suggested selection criteria for tutors.

GRIN relies heavily on the development of strong and timely communications between the GRIN tutor and the classroom teacher. The better the link between the GRIN intervention session and the subsequent classroom lesson, the more impact the program will have on student outcomes.

Careful consideration must be taken to select staff who will implement GRIN within the school. Up to four staff members from a school will attend professional learning over three days. Once the staff have completed the professional learning, the school will become an accredited GRIN school.
