Teacher involvement in teaching learning process could be enormously important in facilitating students’ mathematics learning. Thus, testing and practicing teaching methodologies in the classroom will have a direct impact on students’ meaningful learning. The Asian Development Bank (ADB) provided the technical assistance (TA-8235) in phase II for mathematics branch, ministry of education in year 2018 to develop the component of teaching delivery. The Classroom Assessment Scoring System (CLASS) tool was introduced to measure teaching effectiveness in Secondary classrooms. This study was piloted in selected three provinces Western, Southern and Sabaragamuwa. Bilingual teachers teaching mathematics were selected for this pilot study. Before extend this pilot study it is needed to find out teacher perceptions on this CLASS tool and identified positive and negative lenses of the observation tool. This tool consists of 3demensions,11 domains
