Abstract
This paper reports findings from the case study component of an investigation designed to evaluate the impact of the Count Me In Too early numeracy program in Years 3 and 4 classrooms. Initial anecdotal evidence indicated that the implementation of the program was more difficult than for the corresponding implementation in Kindergarten to Year 2 classrooms. Through the voices of case study teachers, issues surrounding the implementation of the program and potential barriers to professional development emerge and are explored. Interestingly, suggestions as to how some issues are dealt with and how barriers may be overcome are provided by the teachers themselves.
