The current compulsory education curriculum standard experimental textbook Mathematics is compiled according to the basic idea and the prescribed teaching content of the full-time compulsory education mathematics curriculum standard. On the one hand, we strive to embody the new concept of teaching materials, teaching and learning, and at the same time pay attention to taking measures to make teaching materials innovative, practical and open. On the other hand, paying attention to the relationship between inheritance and development not only embodies the new concept of mathematics teaching reform, but also maintains the fine tradition of traditional mathematics teaching and education in China, making the teaching materials basic, rich and developmental. As a math teacher preparing lessons, how to interpret mineral materials, I think reading mineral materials here can be divided into one solution, two readings and three interpretations. 1. Solution: The solution here is the stage of understanding, understanding and understanding the knowledge content and understanding the writing characteristics of the textbook. The mathematics curriculum of full-time compulsory education is guided by the ideas and principles of compiling a whole set of experimental teaching materials. The structure of textbooks conforms to the principles of pedagogy and psychology and the age characteristics of children. It is rich in content, pays attention to students' experiences, reflects the formation process of knowledge, encourages the diversification of algorithms and problem-solving strategies, changes students' learning methods, and embodies the characteristics of open teaching methods. This is the same feature of the whole set of teaching materials. However, due to different contents and different knowledge stages, teachers should first understand the stage and position of what they teach when preparing lessons. The popular explanation step is that the teacher knows where to make "strength" in preparing lessons. Second, reading: This reading can be divided into three levels, which can be said to be how to make teachers "full of energy" when preparing lessons. (a) direct reading, according to the language, characters, numbers, figures, pictures, what kind of knowledge framework is formed, what kind of knowledge is formed, and what auxiliary means are needed. What should teachers do in the process of knowledge dissection, and can examples and exercises match perfectly? How to highlight key points and break through difficulties in knowledge practice, how to build bridges in knowledge extension and what kind of bridges to build. In the practice of knowledge, we should cultivate students' ability. Textbooks provide materials to cultivate students' emotional attitudes and values. How did these materials appear? That is, teachers first visualize the teaching materials and form a general framework of classroom process. (2) Learn to read. This step is based on the teachers' own ability and level. If you are experienced, you can be condescending and unstoppable in knowledge, and the application of teaching methods and the guidance of learning methods can be well understood. This step can be less laborious or omitted, otherwise you must learn to read. The so-called learning to read is to find relevant information and consult excellent teaching plans. Of course, reading these things requires three realms. The first time there was "it" (referring to things) without "I" (my own things, that is, the aforementioned "direct reading"), the second time there was "it" with "I", and the third time there was "I" without "it". Only by absorbing its essence, throwing away all the shackles of "it" and changing "it" into "me". Remember, "Eating steamed bread chewed by others is tasteless". You can never compare with a gourd painter. To put it bluntly, learning to read is to enrich yourself and add some entertainment capital for yourself. (3) Thinking about reading: With the above-mentioned direct reading background and learning capital, you should think about reading. According to the content of the textbook, we should consider how to use these forms of expression. We should integrate these contents through teachers' language. Operational guidance is to make students understand. What else should be added, such as how to introduce it, whether there are any new bridges in the textbook, or whether these bridges can help students pass smoothly, and what should be prepared. What methods are used to practice, highlight key points, break through difficulties, what means are used to let students spread, expand and extend their knowledge, where there may be embarrassment, and what kind of teaching "wit" is used. What methods can make students in a positive and excited state, so that students can achieve teaching goals and complete teaching tasks in enjoyment and happiness? Third, interpretation, which is the last procedure for teachers to prepare lessons, can also be said to be the crystallization and integration formed after the above-mentioned "interpretation" and "reading". Specifically, in specific teaching, teachers should pay attention to their own mentality, speech speed, tone, body language, teaching AIDS and learning tools that should be prepared before class, how to introduce passion, what teaching methods to use, when to use learning methods, what to set up to revisit old topics and introduce new ones, and consolidate exercises and expand problems. What steps are expected to have problems, what kind of educational wit to use, how to ease the classroom atmosphere, how to let go, move without chaos, be hot without making trouble, disperse "form" without dispersing "spirit", how to teach students in accordance with their aptitude, and the blackboard design is clear, appropriate and artistic. Generally speaking, to interpret teaching materials is to thoroughly understand the teaching materials, dig out the key, difficult and confusing points of the teaching materials, and combine the application of teaching methods with the guidance of learning methods. Of course, students should have a good understanding when reading textbooks. If you don't understand the students' age characteristics, knowledge structure, cognitive ability, acceptance ability, study habits and hobbies, and you can't understand them thoroughly, it is archery without a rake. There is no fixed method for teaching, and there is no end to learning. I sincerely hope to learn from my peers and be honest with them. Be a qualified teacher worthy of the times.
