Teaching practice shows that the enemy of implementing quality education is students' heavy academic burden, and one of the direct factors of the heavy academic burden is the flood of "sea of questions". Now teachers have many teaching AIDS, and students also have matching study books and workbooks. Many teachers hold the attitude of "practice makes perfect" and engage in "sea tactics", focusing only on "quantity" rather than "quality" In fact, this kind of blind "sea tactics" not only leads to the reduction of students' thinking space, which is not conducive to the development of students' ability, but also makes students' homework too heavy and overburdened, which runs counter to quality education, reduces the effect of students' homework, causes serious plagiarism and has a negative impact. Teacher Li Yang has a saying in the process of teaching everyone to learn English: Mastering one problem carefully is better than mastering ten problems in a daze, which is also applicable to the setting of math homework. As a math teacher, we must combine the contents of the class, select the right amount, give full play to the due effectiveness of math homework, avoid using easy-to-master assignment methods, and avoid being too ambitious and eccentric.

Second, homework should be interesting and autonomous.

Interest is the best teacher. Psychological research shows that if a person has a strong interest in an activity, then the efficiency of this activity is high. However, for a long time, due to the influence of the concept of acceptance, teachers didn't think too much when designing homework, but just followed the book, which made many students lose their interest in homework, the aura of learning mathematics and the passion of creation, which seriously affected the healthy development of students. To change this situation, it is necessary to enhance the interest and autonomy of homework in homework design, so that students can concentrate on homework and maintain full enthusiasm, thus improving the quality of homework, forming good interests and hobbies, and forming a virtuous circle of learning while doing. Interesting homework design helps to cultivate students' interest in knowledge, thus extending the classroom space and enabling students to fully explore the potential of studying and discussing mathematics after class.

The author once used a form of homework package to arrange homework. The homework package is just like the mobile phone consumption package. No matter what set meal you choose, you have to spend it. The advantage of homework package is that you should practice no matter what package you choose. I have prepared various "homework packages" for students to choose freely: A "package" (basic homework), B "package" (extended homework) and C "package" (innovative homework). Students can choose the homework they want according to their abilities and preferences. Of course, when choosing a "package", I never rigidly stipulate which students must choose which "package". Students can make their own choices completely, so that they can all feel "I can do it, I can do it, I want to do it" and experience the joy of success. After all, homework is still homework, but with such a new term, students are very interested, which not only enhances the interest of homework, but also embodies the autonomy of students' homework, which greatly mobilizes the enthusiasm of students' homework, because when a person is immersed in what he is most interested in and loves to do, his potential will be maximized.

Third, the assignments should be diversified.

The traditional math homework is a write-and-answer homework. The monotonous homework makes students feel boring, which reduces their enthusiasm for doing homework and is not conducive to training and cultivating students' various skills. Therefore, we should pay attention to the change of homework design, realize the diversification of homework forms, let students experience the fun and happiness of mathematics from the process of various homework, so as to cultivate students' interest in mathematics homework. Paulia believes: "A responsible teacher should choose some meaningful but not too complicated topics to help students explore all aspects of the topics and improve their intelligence and reasoning ability in the process of guiding students to solve problems." . Therefore, teachers should decide whether to assign homework and what kind of homework according to the teaching content and the actual situation of students' learning. It must not be a routine. Homework should be both oral and written; Students need to observe, think and discuss, and students need to operate by themselves; We should not only memorize and apply knowledge, but also have the ability to train and cultivate, reasonably combine and match various forms, so that students can consolidate what they have learned in class and improve their application ability in various forms of homework.

Four, homework layout should be layered design, so as to teach students in accordance with their aptitude.

The Outline of Basic Education Curriculum Reform requires that "teachers should pay attention to students' personality differences, meet the learning needs of different students ... so that every student can be fully developed". Therefore, in the assignment, teachers should establish the concept of "only differences, no poor students", so that students of different levels and levels can experience success, especially innovation success. Because students' physical and mental health is influenced by congenital endowment and acquired factors, there are differences. In order to let students at different levels have a successful experience and a chance to shine, we must adopt the strategy of "homework stratification", so that students at different levels can freely choose the group of homework that suits them and pick their own "fruits", which fully embodies that "everyone learns valuable mathematics and everyone can get the necessary mathematics.

For example, the homework package mentioned above is the hierarchical design of homework from easy to difficult. Package A focuses on "double-base" training and is generally suitable for "students with learning difficulties"; Package B focuses on cultivating students' migration ability and is generally suitable for "intermediate students"; C set meal, innovative questions, focuses on cultivating students' creative problem-solving ability, and is generally suitable for a few "top students" in the class. This kind of homework design can be changed from quantitative to elastic in quantity, and the difficulty and quantity can be controlled reasonably. "Fruit" can be hung where every student can jump up and get it. Students of different levels will no longer have difficulty in finishing their homework. Even if there are difficulties, as long as students or teachers give a little hint, they will finish it. This greatly cultivates students' self-confidence in completing homework, relieves the original psychological pressure of poor students, and also improves the inquiry ability of top students, so that all students develop a positive homework mentality.

To sum up, as a math teacher, we should change the concept of homework, think what students think, optimize the design of math homework, improve the efficiency of homework assignment, change the old face of traditional homework, avoid those mechanical, repetitive and boring inefficient homework, make the "expression" of homework rich and vivid, make students' thinking active, enrich their emotions, and make homework no longer a burden, but
