The review of this unit includes the main contents of this textbook, which is divided into five parts: multiplication and division of decimals, simple equations, polygon area, observation objects and possibilities. Unit 7 "Mathematics Wide Angle" aims to infiltrate the "coding" mathematical thinking method into students through concrete life examples, so that students can initially feel and appreciate the charm of mathematics without making specific requirements. So there is no separate review content in this unit.
In the arrangement of the total review content, the knowledge fields specified in the standard and the order of previous teaching contents are considered at the same time, and some scattered learning contents are appropriately merged, and the internal relationship between knowledge is highlighted, which is convenient for sorting out and comparing during review, so that students can understand and master what they have learned more comprehensively and deeply. For example, review the decimal multiplication and division together to help students grasp the calculation law of decimal multiplication and division as a whole. At the same time, the decimal multiplication and division method is compared with the integer multiplication and division method to strengthen the connection between the two calculation rules.
Here is a brief introduction to the review of each part.
1. Review of Multiplication and Division of Decimals.
The review of decimal multiplication and division is divided into two parts: the calculation rules of decimal multiplication and division, and the decimal multiplication and division to solve practical problems. Because of the internal relationship between decimal multiplication and division and integer multiplication and division in calculation methods, this paper compares and reviews integer multiplication and division with the corresponding decimal multiplication and division, so that students can further consolidate the calculation rules of decimal multiplication and division on the basis of comparing the relations and differences between the two calculation methods. Problem-solving review requires students to comprehensively use the knowledge of decimal multiplication and division to solve problems in real life according to specific situations and quantitative relations.
2. Review of the Unary Equation.
The review of simple equations is divided into three parts: using letters to represent numbers, solving simple equations and solving equations. This semester is the first time for students to get into formal contact with algebra knowledge, which plays an important role in the development of students' algebra thoughts in the future. Because the Standard requires students to use the properties of equations to solve equations, which is different from the previous nine-year compulsory education textbooks, the method of solving equations by using the relationship between the four parts should be combined with the properties of equations to further consolidate the method of solving equations. The review focus of enumerating equations is to let students understand the quantitative relationship in the problem, determine the unknown quantity according to the quantitative relationship, and enumerate equations. At the same time, students are encouraged to list different equations according to their own understanding and cultivate their ability to solve problems flexibly.
3. Review of "polygon area".
Focus on reviewing the calculation of polygon area. The formulas for calculating the area of parallelogram, triangle and trapezoid learned in this semester can be converted into the formulas for calculating the area of graphs learned, and the areas of various combined graphs can be converted into the areas of polygons learned for calculation. Therefore, when reviewing this part of knowledge, we should pay attention to strengthening the connection between knowledge, cultivate students' ability to solve problems by using all kinds of knowledge comprehensively, and at the same time make students gradually form transformed mathematical thinking methods.
4. Review of Observation Object.
The observation object of this semester is a further abstraction of the observation objects from different angles in the first volume of Senior Two. The object of observation is mainly three-dimensional geometric shapes, so that students can identify the projection and relative position of one or more geometric shapes in different directions through actual observation and spatial imagination. When reviewing, we should pay attention to cultivating students' spatial concept and gradually infiltrate the idea of projection geometry through intuitive activities.
5. Review of "possibility".
In the last semester of Grade Three, students have learned about the possibility, but at that time they only stayed at the level of "generalization" and only asked to compare the possibility. This semester, students are required to look for the value of possibility from the perspective of "quantification" with the help of problems in life, and then compare and experience the principle of fairness in the game. Therefore, we can review related knowledge and strengthen the connection of knowledge. Because the knowledge of possibility can not be separated from statistics, we should also take into account the improvement of students' statistical consciousness and ability when reviewing.

the first group
Bing Xin said: "study hard, study hard, study hard", and Suhomlinski said: "Whether you can study or not determines a person's intellectual development." Books are the eternal spiritual food for human beings, and everyone in ancient and modern China and abroad draws nutrition from reading. In reading, you can not only gain knowledge and learn to think, but also get emotional edification and spiritual enjoyment.
This set of textbooks is arranged with the theme of "I love reading", and the selected texts are rich in content and diverse in forms, all of which are closely focused on reading. Stealing Reading vividly and meticulously depicts the psychology and fun of stealing reading, and expresses the love and desire for reading. The dialogue between Miao Miao and Da Shu, through the reading exchange between the little girl and the famous scholars of Peking University, gave us a beneficial feeling of reading. Traveling around the world with books tells us that it is very interesting to be with books and books. It is suggested that we should be good at reading, always reading and always being new, and never tire of reading, and we will gain something. Through the childhood experience of Ye Wenling, a famous writer, my book Heng Guo points out the relationship between absorption and talk in reading and writing. Students have been studying since they can read, and this set of textbooks takes it as a special topic. The first purpose is to guide students to grasp the main content and understand the author's deep feelings for the book. Second, we should be able to combine the reality of study and life and learn some methods of reading and writing. More importantly, let students understand the meaning of reading, stimulate their interest in reading, and gradually develop the habit of reading, thus benefiting for life. This is also the concrete practice of "let students read more books, read good books, read good books and read whole books" proposed in the curriculum standard.
We arranged "comprehensive study" and "reading session" in cooperation with this group's special topics.
Arrange a number of training contents such as oral communication, practice, communication platform, accumulation and display platform in the Chinese Garden to guide students to collect and read famous stories (or read famous sayings) and exchange reading experience with people who love reading. Understand the types of books; Classify your books and make a bibliography; Choose different angles to speak, write reading experience or interview and debate. And closely combine this group's reading and comprehensive learning to exchange reading gains and experiences. In the teaching of this group, teachers should make overall arrangements, strengthen the integration of teaching materials and the combination of extracurricular activities, and strive to combine reading with enlightenment, reading with writing, and reading with activities. Through the study of this group, we strive to make students interested in reading, regard reading as an important part of life, and make reading a need for growth. If a Chinese teacher can make his students fall in love with reading, then he has made great contributions.
The teaching materials of this teaching group can use 10- 14 hours, intensive reading 4-5 hours, skimming 2 hours, oral communication 1 hour, exercise 2 hours, "communication platform" and "exhibition platform" 1-2 hours.
the second group
Hometown, in the hearts of wanderers, is always the warmest, most difficult to give up and most fascinating place. The poems and essays selected by this group can be said to be the swan song of homesickness. The poet "boating in Guazhou" in Three Ancient Poems looked at his hometown with the boat in Guazhou, and I don't know when he can return to his hometown. Qiu Si wrote that the poet wrote a letter to his family in Luoyang, but he was helpless and unable to tell them. "Sauvignon Blanc" is about southern soldiers fighting at the border. In the sound of snow and snow in the north, they can't sleep at night because they miss their hometown. The Soul of Plum Blossom describes an old man who lives far away in a foreign country, pinning his love for the plum blossom and expressing his undying attachment to his motherland and hometown. The author of "Rain on Osmanthus Flowers" has fond memories and deep nostalgia for childhood flowers. "Little Bridge Flowing Water Family" wrote down the beautiful hometown life in memory with deep affection. Long homesickness, deep homesickness, like a cup of tea, full of tea fragrance. The more you taste, the more mellow and strong it is.
The purpose of compiling this textbook is to let students experience the author's homesickness and love thoughts and feelings through reading; Second, through comparative reading, let students know that homesickness is the same, but the ways and objects of homesickness vary from person to person, and the things that cause homesickness are also different, so as to realize that the author's feelings are expressed through some scenery or things; Third, through reading, guide the taste of language and enrich students' language accumulation.
Teaching this set of textbooks should guide students to fully read, experience with heart, accumulate beautiful language in the book and feel the beautiful feelings of the characters. In line with this group's special topic, the "oral communication homework" arranged for students to plan activities with the theme of "deep homesickness", write imaginary compositions with the content of "returning to my hometown in 20 years" as the "communication platform", arranged the content and expression of communication, guided students to accumulate poems expressing homesickness, and showed their homework expressing their love for their hometown. In teaching, teachers should take care of the arrangement characteristics of this group as a whole, and organically combine feelings with writing comprehension, reading and expression, language accumulation and language practice to achieve the optimization of teaching effect.
This group of textbooks can use 1 1- 14 class hours. Among them, intensive reading takes 4-5 hours, skimming takes 2-3 hours, oral communication 1 hour, exercise takes 2-3 hours, "communication platform" and "accumulation" 1 hour, and "exhibition platform" 1 hour.
Third groups
This set of textbooks has arranged four expositions to cultivate students' scientific literacy and humanistic literacy. Whales and squirrels introduced some knowledge about animals, which opened a scientific door for students to explore the animal world. "New Glass" introduces the characteristics and uses of some new glasses, so that students can feel the magic and power of science and technology. If there is no dust, it reveals the great discovery of scientists and explains the important relationship between dust and human beings.
Several texts in this set of textbooks are extensions and developments of previous descriptive articles. On the one hand, the purpose of compiling this set of textbooks is to let students know some scientific knowledge, stimulate their interest in exploring the mysteries of nature and science, and stimulate their learning consciousness; On the other hand, let students know the methods of explanation and how the author uses words accurately and vividly, and use them in practice.
When teaching this set of textbooks, we should pay attention to the following points: 1 We should have the consciousness of expanding curriculum resources and strengthening discipline integration. On the one hand, students should be encouraged to collect relevant information through various channels to expand their knowledge; On the other hand, with the help of science teachers, efforts should be made to improve students' scientific literacy. 2. The teaching content should be arranged as a whole, and the study of the text should be organically combined with oral communication, practice, communication platform and extracurricular bookstore. For example, as soon as we enter the study of this group of texts, we will recommend excellent popular science works, guide students to read, and hold a reading exchange meeting at the end of this group's teaching; When learning each text, students should be instructed to take notes or cards carefully, summarize the knowledge and information obtained from the text, and list the expression methods and examples used in the text to prepare for the unit summary in the "communication platform". 3. Don't treat Chinese class as a scientific common sense class. Some scientific knowledge involved in this article should not be delved into in Chinese class. The focus of teaching should be to understand the main content expressed by language and learn the expression methods of expository writing.
This group of textbooks can use 1 1- 14 class hours. Among them, intensive reading takes 4-5 hours, skimming takes 2-3 hours, oral communication and practice takes 3-4 hours, and review and development takes 2 hours.
Fourth groups
This group of texts includes two intensive reading texts: Inspiration of Fishing and Peanut, and two skimming texts: There is more than one way to the square and Pearl Bird. Every text contains profound philosophy on how to be a man. The four texts focus on the learning topic of this unit "Enlightenment of Life", telling us that moral judgment may be simple, but it is difficult to practice; There is more than one way to the square, so is life; Being a man can't be just decent, but bad for others; Trust can often create a beautiful realm-people really feel that life is indeed a book that can never be read enough. Although there is not a word in the book, it is full of knowledge, depending on whether we are good at reading.
The four texts selected by this group have strong plots-students love reading; The language is concise and clear-students can read it; Profound meaning-it may affect students' life, but students may not really understand it, which is the focus of text teaching in this unit. Fortunately, every text, especially two intensive reading texts, has key sentences that directly point out the main idea of the article. We can use these key sentences to guide students to understand deeply, not only to understand the text itself, but also to extend to life, find something from it and get inspiration-this is also the goal of cultivating Chinese ability, emotion, attitude and values that this unit needs to implement.
To teach this group of texts, we must first guide students into the text, be moved by the people and things in the text, and be inspired and educated from it; Then, lead the students out of the text, return to the colorful reality, get in touch with the reality of life and feel others.
The importance of sincerity and honesty, teachers and students work together to add a new beautiful chapter to the book of life. Finally, we have to go back to the text: we can read the key sentences that give people profound enlightenment, keep them in mind, consciously use these philosophical words to guide and regulate our behavior, and be an honest, kind, optimistic and beneficial person-this is the common spiritual expectation of the author of the text, us and the students.
In addition to the text, this group of textbooks also arranges learning contents related to the topic of this unit in "oral communication practice" and "review and expansion" "Oral communication practice" requires you to choose an inspiring thing and a famous aphorism that leaves a deep impression on you from your daily life (or rely on the cartoons provided). On the basis of oral communication, you can write clearly what happened and what you got from it. The "communication platform", "accumulated over a long period" and "idiom stories" in Review and Development not only help students review and sort out the key sentences in this group of texts, but also supplement them with famous sayings and aphorisms with warning significance, so as to further develop ideas and enrich materials for students to accumulate feelings.
This group of textbooks can use 10- 13 hours, including 4-5 hours of intensive reading, 2-3 hours of skimming, 3 hours of oral communication practice and 1-2 hours of review and development.
