Towards the end of each of the series of in-service workshops, a test consisting of eight questions was administered to assess the teachers’ grasps of the mathematical concepts of combinatorics. In the last of this series of in-service workshops, together with the test, a survey was also administered to the teachers on their opinions of the eight combinatorics problems and their belief about these questions (whether they believed these questions were routine; non-routine; not in the syllabus but useful non-routine problems; completely not required for the syllabus). This paper presents the finding of this survey on the teachers’ perception of these problems on combinatorics.
