In the subject of mathematics, performance tasks are essential to data-driven assessment and instruction. Students are required to use mathematical principles and skills in real-world circumstances or complex issues that they are given to work on. Students that participate in performance assignments exhibit their grasp of mathematics as well as their capacity for critical analysis, reasoning, and creative problem-solving. Performance problems provide instructors with a wealth of data that extends beyond conventional assessments of mathematical ability. Teachers can acquire valuable insights into their students' depth of comprehension, problem-solving techniques, and effective communication of mathematical reasoning by closely observing and evaluating their responses. Additionally, because performance activities allow teachers to customize feedback and support to each student's unique requirements, they offer a chance for differentiated instruction. In order to successfully scaffold students' mathematics learning, educators can pinpoint areas of strength and weakness, modify their instructional strategies, and provide focused interventions by examining the results of performance tests. Performance tasks are a useful instrument in the data-driven assessment and education process because they help students get a deeper knowledge of mathematics and develop their critical thinking abilities.
