1, understand the importance of quantitative relationship: quantitative relationship is the basis of mathematics, involving basic operations such as addition, subtraction, multiplication and division. Understanding quantitative relations can help students better understand mathematical concepts and improve their ability to solve problems.

2. Clear teaching objectives: When teaching quantitative relations, we must first clear the teaching objectives. This includes cultivating students to master the basic concepts, methods and skills of quantitative relations, as well as focusing on cultivating students' thinking ability and problem-solving ability.

3. Innovative teaching methods: In order to make students better understand and master the quantitative relationship, we need innovative teaching methods. Through gamification teaching, case analysis and group discussion, students can actively participate in and learn in a pleasant atmosphere.

4. Cultivate students' thinking ability: Mathematics is not only calculation, but more importantly, cultivate students' thinking ability. When teaching quantitative relations, we should guide students to think about the nature of problems and stimulate their curiosity and thirst for knowledge.

5. Pay attention to the connection with real life: Mathematics is closely connected with daily life. When teaching quantitative relations, examples from life can be introduced to make students feel the practical application of mathematics in life, so as to better understand and master knowledge.

6. Continuous learning and self-improvement: As teachers, we need to keep learning and self-improvement. By participating in training, reading professional books and communicating with other teachers, I can constantly improve my teaching level and professional quality.

Through this training, I deeply realized the importance of quantitative relationship, made clear the teaching objectives, mastered effective teaching methods, and stimulated my motivation of continuous learning and self-improvement. I believe that these experiences and knowledge will have a positive impact on my teaching work and help me better cultivate students' mathematical literacy and problem-solving ability.

Application of quantitative relation

1, proportional relationship: proportional relationship is a way to describe the relative size relationship between two or more quantities. For example, in the business field, we need to calculate the ratio of cost to benefit in order to make reasonable decisions. In the medical field, proportional relationship is also widely used in the calculation of drug dosage to ensure that patients get proper treatment.

2. Percent calculation: Percent is a common expression of quantity relation, which represents one numerical value as a percentage of another numerical value. For example, we often use percentages to calculate discounts and tax rates. In statistics, percentage is also widely used to represent the relative frequency and proportion of data.

3. Crossover method: Crossover method is used to solve the problem of two equal scores. For example, we can solve the sum or difference of two numbers in this way.
