The correct goal means that the teaching goal should not only meet the requirements of curriculum standards, but also meet the actual situation of students. Teaching goal is the basis of designing teaching process, the general guiding ideology of classroom teaching, and the starting point and final destination of classroom teaching. How to make a concrete and feasible teaching goal? First of all, we should carefully study the teaching materials, combine the objectives and teaching contents of the mathematics course, and work out the teaching plan of this lesson: what knowledge students should master, what skills they should form, what proficiency they should achieve, and what methods to solve problems. This is the double-base target. Secondly, we should consider what kind of thinking ability students can cultivate through the teaching of this knowledge, which is the goal of thinking ability. Thirdly, through the imparting of these knowledge, we should think about what kind of ideological education and good moral quality students should have, which is the requirement of infiltrating ideological education. Finally, we should consider where students can receive innovative education and how to cultivate their innovative consciousness and creativity. This is the requirement of innovative education and the most important goal of classroom teaching.
