**5.1 Use assessments to establish and describe the students' misconceptions**

Teachers' knowledge of students' misconceptions should go a long way in equipping them to prepare mathematics activities in their classroom. This will allow them to plan instruction targeting the student misunderstandings. I can conclude that formative assessment, like homework, can be used to locate mistakes and to figure out why they were made and how to provide support to students by way of explanation and tutoring [19]. This approach can help teachers learn some pedagogical lessons from exploring the content of students' procedural knowledge and understanding [9]. That is, when students make mistakes, they must be considered as opportunities for reconstruction of their knowledge.
