Methods of teaching students to classify mathematical problems

In this article, mathematical tasks: problem-solving tasks are described. The mathematical tasks are classified according to their teaching purpose and theses tasks can provide students with opportunities to learn new mathematics and to develop mathematical processes including problem-solving strategies. The classification of mathematical tasks will help teachers to understand more about the purpose and characteristics of the diverse types of tasks so that they-can choose appropriate tasks to enhance the students-mental structures and to assess the-various aspects of their learning.
