1, the content of learning situation analysis

Students often come into contact with triangles in daily life, and the fourth-grade students have a certain perceptual knowledge of triangles, but the preliminary knowledge of geometry, whether it is the characteristics of lines, surfaces and bodies or the characteristics and characteristics of graphics, is abstract for primary school students. To solve the contradiction between the abstraction of mathematics and the thinking characteristics of primary school students, we must make full use of the intuition of mathematics in teaching.

2. The purpose of learning situation analysis

The teaching process is the process of teacher-student interaction, and the essence of teacher-student interaction is spiritual communication, communication, understanding and influence. The interaction between teachers and students in the classroom is the combination of "teachers' teaching" and "students' learning".

As teachers, we should cross the generation gap of age and culture in class by analyzing the learning situation, design the interactive route before class, play the role of "the chief among equals" in class, and build a bridge for students to ask questions and talk.

The benefits of learning mathematics:

1. Mathematics is the basis of all re-education and an important channel for cultivating logical thinking. Don't just look at the present, think about the long term. Mathematics is the soul of all disciplines.

2. Mathematics is the foundation of all sciences, and all major scientific and technological progress is closely related to mathematics. Without mathematics, there would be no computers, televisions and space shuttles, and there would be no such colorful life today.

3. Mathematics is a tool discipline, which is the basis of learning other disciplines and also a discipline to improve people's ability of judgment, analysis and understanding.

Mathematics is not only a science, but also a universally applicable technology. It is the door and key to science. Learning mathematics is a very important measure to make oneself rational, and mathematics itself has its fun.

5. Mathematics can make you think about any problem more carefully without being confused. It can also make your brain react flexibly and deal with emergencies more rationally.

6. Mathematics gives people not only knowledge, but also ability, including observing experiments, collecting information, inductive analogy, intuitive judgment, logical reasoning, modeling and accurate calculation.
