Numbers and Algebra 1, Unit 1 "Numbers in Life". In this unit, students will experience the process of abstracting the model of numbers from specific situations through activities such as "counting pencils": they can count, read and write numbers within 100; Grasp the relative size relationship of numbers in specific situations; Be able to express and communicate with numbers and experience the close relationship between numbers and daily life. 2. Unit 3 "Add and subtract (1)", Unit 5 "Add and subtract (2)" and Unit 7 "Add and subtract (3)". In the study of these units, combined with life situations, students will experience the process of abstracting addition and subtraction formulas from specific situations and further understand the meaning of addition and subtraction; Explore and master the calculation methods of addition and subtraction within 100 (including no carry, no abdication, carry and abdication), addition, subtraction and combination of addition and subtraction, and calculate correctly; Can estimate the operation results according to specific problems; Initially learn to apply addition and subtraction to solve simple problems in life and feel the close relationship between addition and subtraction and daily life. Unit 6 "Shopping". In this unit, students will learn about yuan, jiao, fen and their relationship through shopping activities and life experiences, and get to know RMB of various denominations; Combined with the shopping situation, simple calculations are made to solve simple practical problems. Two. Space and graphics 1. Unit 2 "Observation and Measurement". In this unit, students will observe the simple objects around them, initially understand that the shapes seen from different angles may be different, and develop the concept of space; In actual measurement and communication, we should understand the necessity of unifying measurement units, the practical significance of centimeters and meters, the significance of centimeters and meters, and the relationship between centimeters and meters, so as to estimate and use measuring tools to measure the length of objects. Unit 4 "Interesting Graphics". In this unit, students will go through the process from three-dimensional graphics to plane graphics, know the plane graphics such as rectangle, square, triangle and circle, and initially realize that they are on the body; Through a large number of "hands-on" activities, we can further understand the plane graphics such as rectangle, square, triangle and circle, accumulate experience in mathematical activities and develop the concept of space; Experience the process of abstracting graphics from life situations, feel the richness of the graphic world and design interesting patterns. Three. Statistics and Probability Unit 8 Statistics. In this unit, students will experience the process of data collection, collation and analysis through simple investigation activities. Have a preliminary understanding of bar graph, can ask and answer simple questions according to the data in the chart, and can communicate with peers. Four. Practical Activities This textbook has arranged three practical activities: "I grew up with Xiaoshu", "Small Games" and "Today I am the master", aiming at comprehensively applying what I have learned to solve practical problems. At the same time, in the study of other specific contents, activities such as hands-on and small investigation are arranged for the practical application of a certain knowledge. In these activities, students will use the knowledge and methods they have learned to solve problems and feel the role of mathematics in daily life; Get some preliminary experience in mathematics activities and develop the ability to solve problems and think with mathematics; In the process of cooperation and communication with peers, cultivate interest and self-confidence in mathematics learning. Teaching suggestions: First, it is very important to cultivate students' interest in mathematics learning and good habits. Teachers should pay attention to stimulate students' interest in learning and organize students to carry out various learning activities by using the materials provided by textbooks. In teaching, teachers should first pay attention to the enthusiasm of students to participate in learning activities, whether the students' answers are correct or wrong or whether the language is complete. Teachers can delay the evaluation and encourage students to actively participate. Teachers should pay attention to students' speeches, and pay special attention not to train students in a unified and stylized language, and not to let students express their thoughts in their own language. Teachers should make every student like class first, like teachers, and then like math. It is impossible to cultivate students' good study habits overnight. Teachers should not be eager for success, put forward unified and rigid requirements for students too early, but should adopt a step-by-step approach. Good study habits cannot be simply understood as external forms such as asking students to sit well in class and raise their hands to speak. More importantly, we should gradually guide students to learn to think independently, dare to ask questions, listen carefully to other people's opinions, and be willing to express their own ideas. Second, let students learn mathematics in vivid and concrete situations. In mathematics teaching, teachers should make full use of students' life experience, design vivid, interesting and intuitive mathematics activities, such as telling stories, playing games, demonstrating intuitively and simulating performances, etc., to stimulate students' interest in learning, let students understand and know mathematics knowledge in vivid and concrete situations, and encourage every student to participate in the mathematics learning process with hands, mouth and brain. For example, in the teaching of the practical activity "Small Games", teachers can design the contents of the teaching materials into fairy tales, and naturally introduce questions that need to be discussed in the process of telling stories; Students can also be guided to play different roles and perform simulated performances; It can also be combined with the school sports meeting to encourage students to find math problems and try to solve them. Thirdly, it is an important way for students to learn mathematics to guide them to think independently and cooperate with their peers. In teaching, teachers should encourage students to think in specific activities, encourage students to express their opinions and communicate with their peers. In the process of thinking and communication, teachers should provide appropriate help and guidance, be good at choosing valuable questions or opinions among students, and guide students to discuss in order to find answers to questions. Teachers can consciously cultivate students' desire and habit of communicating with others, so that students can gradually learn to describe their ideas in an appropriate way and learn to listen to others' opinions. Fourth, cultivate students' initial ability to ask and solve problems. The textbook pays special attention to cultivating students' awareness and ability to ask questions, and has set up columns such as "question bank" to encourage students to ask questions. Even if some problems cannot be solved for a while, they can be solved after the "problem bank". In teaching, teachers should make full use of students' existing knowledge and experience, guide students to apply what they have learned to life at any time, solve mathematics problems around them, try to find mathematics problems from daily life, understand the role of mathematics in real life and realize the importance of learning mathematics. 5. The creative use of textbooks only provides basic clues for students' mathematical activities. In teaching, teachers should creatively use teaching materials and design the teaching process according to the characteristics and actual situation of their classmates. Teachers should also record their teaching design and teaching reflection in time, and constantly improve their teaching ideas and teaching methods. Class schedule: 1.
