This study was conducted in response to the curriculum reform in Indonesia which have encouraged a different approach to teach the mathematics content employing innovative methodology or model in teaching and learning. This study aimed to understand the secondary school mathematics teachers’ Pedagogical Content Knowledge (PCK) towards curriculum reformation. Every participant was interviewed in relation to the domain of PCK, and some intended teaching practice in K-13. The result shows that each teacher has a unique approach to teaching system of linear equations of three variables (SLETV) in curriculum reform. Though the content structures are different, the patterns for teaching two variables to three variables of SLETV are similar. Some intended teaching may still not be implemented regarding students’ and classroom teaching/practices condition which in the end makes the teachers return to the old paradigm of teaching. Hence, although the government has provided good efforts in suggesting some innovative teaching practices to increase the achievement of students, those ideas may still not be executed in the classroom practice.
