The Mathematics curriculum at the upper primary level aims to develop several mathematical skills and processes in children such as handling abstraction, problem-solving, mathematical communication, conjecturing, and searching for proofs. Key PointsRole of a Teacher at the middle school level- The Aims of teaching-learning mathematics should include creativity, problem-solving skills, and critical thinking. He must have Knowledge of mathematics and content-specific pedagogy. The prime focus should be on engaging every child with a sense of success, while at the same time offering . challenges to the emerging mathematicians. Assessment needs to be focused on examining children’s mathematization abilities and understanding rather than procedural knowledge. He should always focus on the teaching-learning process and student learning. Multiple resources should be used by teachers of mathematics so that appropriate experiences can be provided to children according to their learning requirements. Thus, Knowledge of mathematics and content-specific pedagogy and Reflecting on the teaching-learning process and student learning envision the growth of a mathematics teacher at the middle school level.
