First, establish self-confidence and cultivate perseverance. Mathematics exercises in primary schools, especially in senior grades, often involve complex calculations, which are difficult to understand and prove by reasoning. Students should have enough confidence, tenacious perseverance and good habits of being serious and careful in order to finish it from beginning to end.

Second, correct students' learning attitude and make clear their learning objectives. Let students fully realize the importance of math exercises after class. Whether it is preview exercises, classroom exercises, or after-school homework and review exercises, tell students that they can't just be satisfied with finding solutions to problems or simply getting answers, rather than detailed exercises. Students should avoid making "superior" mistakes. The actual contact after class can not only improve the speed of answering questions. Mastering problem-solving skills, many new problems often appear in practice, which can not only consolidate knowledge points, but also be the most effective test for our whole mathematics learning process;

Third, form a good habit of thinking seriously, thinking first, answering later and checking again. For example, when encountering a problem, especially a problem without a specific solution, students can't practice and answer blindly, and invalid calculation is just futile, especially in exams, which wastes time and energy. First, we should deeply understand the meaning of the problem and distinguish the meaning of the problem. Find out the known conditions, implied conditions and problems to be solved, think carefully, grasp the key words in the topic, and finally answer. Remember, after the problem is solved, you must check it again and again.
