1, Numbers and Algebra
It mainly includes the understanding, operation and quantitative relationship of numbers, so as to cultivate students' sense of numbers, operation ability and reasoning consciousness.
The understanding of logarithm involves different types of numbers such as natural numbers, integers, rational numbers, irrational numbers and real numbers, as well as their size comparison, operation rules, approximate calculation and so on. Learning this part can help students understand the concept and nature of numbers, master operation skills, and cultivate their sense of numbers and estimation ability.
2, graphics and geometry
It mainly includes the understanding, measurement, position and movement of graphics. To cultivate students' sense of space, thinking in images and creativity. Graphic geometry is an important field of mathematics, which mainly studies all kinds of graphics in space and plane, as well as their properties, classification, measurement, movement and position.
Graphics and geometry can help us know and understand the spatial form in the real world, and cultivate our spatial concept, geometric intuition and reasoning ability. The course content of graphics and geometry focuses on developing students' spatial concept, geometric intuition and reasoning ability.
3. Statistics and probability
It mainly includes data collection, collation and analysis, as well as the basic concept and application of probability, so as to cultivate students' data awareness, analytical ability and judgment ability.
Statistics and probability is an important field of mathematics, which mainly studies the collection, collation, analysis and inference of data, as well as the laws and characteristics of random phenomena. Statistics and probability can help us discover information and knowledge from data, deal with uncertainty and variability, solve practical problems, and cultivate our data awareness, analytical ability and judgment ability.
4. Synthesis and practice
It mainly includes interdisciplinary thematic learning, project-based learning and other ways to design real and complex problems, guide students to comprehensively use mathematical knowledge and methods to solve problems, and cultivate students' model awareness, application awareness and practical ability.
We should attach importance to students' own development needs and respect students' independent choices. Teachers should be good at guiding students to focus on the theme of activities, cut in from a specific angle, choose specific activities, set their own goals and tasks, and improve students' ability of independent planning and management.
