Increase the chances of hands-on operation, so that students can get the correct graphical representation and correctly calculate the perimeter, area and volume of some geometric shapes. 10, can grasp the rate of progress between units, can correctly convert the number of points. [1] A brief analysis of the textbooks of the Chinese teaching work plan : The eighth volume of textbooks is organized in the order of language knowledge and ability training. At the time of writing the textbook, the teaching objectives of the sixth year of the sixth year of the Compulsory Education Full-time National Language Teaching Guidance Outline were decomposed into several training points. These training points are based on the level of difficulty and the level of physical and mental development of children in the fourth grade. Some of them have been arranged in the seventh volume of teaching, and the remaining parts are arranged in this volume. This book has three clues: reading training, training and listening and speaking training. From the vertical perspective, the first training arranges training points according to the principle of easy to difficult and from shallow to deep; from the horizontal perspective, these training points are grouped according to the principle of horizontal linkage and coordinated development. Each unit selects texts and exercises according to the teaching objectives. There are 8 units in this book. Each unit has a learning guide for reading training in this unit. It tells students what the focus of this unit is on reading and how to apply it. Each unit has 3 texts to be selected for this reading training program. Each of the first, third, fifth, and seventh units has one elective text, marked with △. There is 1 training session per unit, and 1st, 3rd, 5th, and 7th units have 1 listening and speaking training. There is also a unit exercise per unit, mainly to review the content of this unit, but there is a proper extension of language knowledge and ability training. In this way, the textbooks in this book have a total of 24 texts, 4 texts, 8 training sessions, 4 training sessions, and 8 unit exercises. The ideological and moral education of the Chinese subject has the characteristics of scattered disorder and richness and diversity. The content of ideological education in this booklet is very rich, including patriotic education, revolutionary traditional education, socialism-oriented education, and science, science-loving education, and so on. However, the texts are not arranged in the order of ideology and morality education. Therefore, the ideological and moral education of a unit is not carried out around the same center. The general purpose of this book is to: 1. Use Chinese Pinyin to help literate, read and learn 257 Mandarin literacy. Can recognize common homophones and near-words, and can read multi-phonetic words that have been learned. Learn to use the method of strokes to check difficult words and learn to be independent. 2, will read and write 560 words, understand the meaning, some will be used verbally or in writing. 3, initially learned to write pen words, written correctly, correct, neat. Initially learn to use the brush to post, pay attention to the structure of the word, and initially develop the habit of serious copying. 4. Initially develop the habit of politely listening to people's speeches, listening and thinking, listening to the places where others are not properly expressed; listening to the radio and saying the main points; being able to introduce the situation clearly and can be organized Answer the questions. 5, will read the text correctly, fluently and emotionally, can understand the meaning of long sentences; learn to use commonly used reading marks when reading; can follow the several aspects of things and grasp the key segments, can say the meaning of the paragraph Can repeat the text in detail. Know the ellipsis. Can initially read the instructions and follow the instructions. 6. Preliminary learning has a sequence of observations of the pictures and the surrounding things in a focused manner. It can be organized to clearly and clearly describe the activities of the visit and initially learn to write simple and written articles, and the sentences are consistent and coherent. Initially learn to write a notice and learn to write letters to the elders. The book title number will be used. Master the commonly used modification and modification symbols, and modify the sentences with obvious errors. Through the training of language and writing, students will be more enthusiastic about the motherland, and they will win glory for the motherland from childhood; inherit and carry forward the revolutionary tradition, observe discipline, help others, work hard, and actively; and cultivate the thoughts and feelings that love science. Teaching measures: 1. Accurately grasp the teaching objectives, and do not arbitrarily raise or lower. 2. Solid language training. This semester focuses on segmental training, but should continue to pay attention to students' literacy and writing, help them to accumulate vocabulary and sentence patterns, and master basic expression methods. Classroom teaching ensures that students have sufficient time to read, meditate and perform various other exercises. It is necessary to design effective methods, expand the training surface, and strive to involve all students in the whole class to ensure that students have enough time for individual activities. Teachers should strictly demand, promptly feedback and correct, and emphasize practical results. 3. Pay attention to the connection between listening, speaking, reading and writing. Students should be taught by reading and reading. In the composition training, we should make full use of the expressions learned in the texts, encourage students to write familiar things and improve their language skills. 4. Implement the training focus of each unit and pay attention to the guidance of learning methods. In reading teaching, it is necessary to organize teaching with the focus of training points, and to focus on training objectives from content analysis. When teaching texts, it is important to consider how to let students master the basic reading skills prescribed by the training points of this unit, avoiding words, words, sentences, and articles to go through once, using the average power, not just grasping the content analysis, ignoring the training focus. . In the focus of reading training, we must give full play to the role of "learning tips" before each unit, and timely guide students to master the learning methods according to the characteristics of the text. 5. Continue to do a good job in training and replenishing the poor, and vigorously improve the middle school. [1]
