Turkish Mathematics Curriculum (TMC) is based on the principle that ‘Every child can learn mathematics’. In the TMC, special attention is given to development of students’ conceptual knowledge and problem solving skills, along with procedural knowledge. Further, the relationships between conceptual and procedural knowledge are strongly underlined. In this conceptually-driven approach, “learning mathematics with understanding” is the primary goal to be achieved by all students (MONE, 2009b).
