1, method:

(1) Classification memory method is to classify materials according to their nature, characteristics and internal relations, thus helping students to remember a lot of knowledge. For example, after learning the unit of measurement, everything you have learned can be summarized into five categories: length units; Area unit; Volume and unit of volume; Weight unit; Time unit.

This classification can easily systematize, organize and memorize complex things.

(2) Regular memory method. That is, according to the internal relations of things, find out the regular things to remember. For example, memory length unit, area unit, unit of volume transformation method and aggregation method. Chemical method and polymerization method are reciprocal, that is, high-level unit value × rate = low-level unit value, and low-level unit value/rate = high-level unit value.

Mastering these two laws will solve the problem of chemical polymerization. Regular memory requires students to process and sort out the relevant materials they have learned with their brains, so the memory is firm.

(3) List memory method is to list some easily confused memory materials in a table to achieve the purpose of memory. This method is obvious, intuitive and comparative. For example, to remember the differences between the three concepts of prime number, prime factor and coprime number, you can make a table to help students remember.

2. Teaching methods

(1) Prepare carefully before class. The purpose of preview is to listen to the teacher better. Through preview, the mastery level should reach 80%, and listen to the teacher to answer such questions with questions that you don't understand in preview. Preview can also improve the overall efficiency of attending classes.

Specific preview method: finish the topics in the book and draw the knowledge points. The whole process lasts about 15-20 minutes. If time permits, you can also finish your homework.

(2) Review in time after class. After finishing your homework, sort out what the teacher said that day, and you can do extracurricular problems for about 25 minutes. You can choose an extracurricular book that suits you according to your own needs, and its extracurricular topic content is likely to be the class you attended today.

Step 3 Practice methods

(1) Correct attitude and fully realize the importance of mathematical practice. Practice can not only improve the answering speed and master the answering skills, but also often lead to many new problems in practice.

(2) Have confidence and willpower. Mathematical exercises often involve complicated calculations and profound proofs. You should have enough confidence, tenacious will and patient and meticulous habits.
