First, the analysis of students' situation
Through the study of the new textbook, students have initially adapted to the characteristics of the new curriculum and can complete the learning tasks with certain personality. Generally speaking, the basis of the two classes is similar. The top students in Class 3 are almost the same as those in Class 4. But there are several underachievers in Class (2). The study habits of the two classes are good, so this semester's teaching should focus on the cultivation of good listening habits and the training of mathematical thinking ability. In addition, pay attention to students' ideological trends, actively educate and guide students, and let students gradually fall in love with mathematics.
Second, teaching material analysis
The content of this course covers all fields of mathematics teaching content, and many reading materials reflecting mathematics culture are arranged in combination with the teaching content, which is helpful for students to understand the close relationship between mathematics and human life and feel the value of mathematics. Specific performance:
There are three units in the field of number and algebra. The main contents include learning division with remainder on the basis of division in the table, and combining examples and surveys, let students realize that there are numbers greater than "hundred" in life and stimulate their interest in learning. Through practical operation and observation, let students experience the number of "one thousand" and "ten thousand" according to the specific situation, and explore the calculation methods of addition, subtraction, addition and subtraction within ten thousand. Through the study of time, minutes and seconds, a good habit of observing and cherishing time is initially formed. There are three units in the field of graphics and geometry, which provide students with rich learning resources and pay attention to students' hands-on practice and positive thinking. With the help of realistic mathematical activities, "direction and position" can identify and determine eight directions, describe the position of objects, and identify simple road maps. Through a large number of hands-on operations and practical activities, the Survey initially established the length concepts of "1 km", "1 decimeter" and "1 mm", as well as the relationship between units, and cultivated students' estimation consciousness. "Understanding graphics" can identify right angles, acute angles and obtuse angles through real life scenes; Through hands-on operation, we can understand the characteristics of rectangles and squares and intuitively understand parallelograms. In statistics and probability, students will go through the process of data investigation, collection and arrangement, answer some simple questions according to some data in the chart, exchange ideas with their peers, and initially form statistical consciousness. In simple guessing activities, we initially feel uncertainty, and experience that some events are certain and some are uncertain. In addition, there is a comprehensive practical activity "Mathematics Interest".
The knowledge points of this course are scattered and numerous, and the difficulty is much higher than before. Although the second-year students are young, they already have some knowledge and life experience. As long as they pay attention to the training of thinking ability, oral expression ability and hands-on operation ability in their usual study and develop a down-to-earth and meticulous learning attitude, they should be able to successfully complete their learning tasks and lay a good foundation for future study.
Third, learning objectives.
(a) Numbers and algebra
1. Explore and master the trial quotient method of division with remainder in combination with the activity of dividing things; This paper explores the relationship between addition and subtraction within ten thousand years through specific situations.
The mixed calculation method of addition, continuous subtraction and addition and subtraction can form the habit of estimating the approximate range of calculation results, ask questions in specific situations, and use the knowledge learned to solve some simple practical problems.
2. Combining examples and surveys, let students realize that there are more numbers than "hundred" in life, and stimulate students' interest in learning. Through practical operation and observation, let students experience how big "one thousand" and "ten thousand" are, and can estimate and understand the numbers within ten thousand according to the actual situation.
Its numerical order will be expressed and communicated by numbers within 10,000, and the size of numbers within 10,000 will be described by words or symbols to cultivate students' sense of numbers.
3. Students study in hours, minutes and seconds, and initially form a good habit of observing and cherishing time. In the actual situation, we can accurately read the time on the clock face and tell the elapsed time by knowing the hours, minutes and seconds, initially understanding their practical meanings and mastering the speed of progress between hours, minutes and seconds.
(b) graphics and geometry
1. Know eight directions with the help of realistic mathematical activities. Given one direction (east, south, west and north), you can identify the other seven directions. You can use these words to describe the position of an object. Know the simple road map and tell the direction and way of walking from the starting point to the destination according to the road map.
2. Through hands-on operation and practical activities, the length concepts of "1 km", "1 decimeter" and "1 mm" and the relationship between units have been preliminarily established; Cultivate students' estimation consciousness.
3. Understand the angle through real life. Can identify right angles, acute angles and obtuse angles. Through hands-on operation, we can understand the characteristics of rectangles and squares and intuitively understand parallelograms.
(3) Statistics and probability
Students will experience the process of data investigation, collection and arrangement, answer some simple questions according to some data in the chart, exchange ideas with their peers, and initially form statistical consciousness.
Fourth, teaching measures:
1, we should grasp the teaching objectives as a whole. Not only by experience, but how to mention it in the past and how to mention it now; Can't transfer textbooks. All the contents in the textbook should obey the unified teaching requirements, but should be adjusted appropriately according to the syllabus and teaching situation. It is necessary to prevent increasing students' learning burden.
2. Make full use of students' life experience, let students learn mathematics in concrete and vivid situations, and design vivid and interesting mathematics activities, such as games, storytelling, visual performances and simulation performances. Stimulate students' interest in learning and let them understand and know mathematics knowledge in vivid and interesting situations; At the same time, make full use of learning tools to cultivate students' hands-on operation ability.
3. In classroom teaching, let students take care of students with learning difficulties and students with slow thinking in combination with their real life, check for missing parts, solve problems, and practice more in daily life, which embodies the truth that mathematics comes from life and stimulates their interest in learning.
4. Students who have spare capacity for learning will further improve and expand on the basis of mastering the basic knowledge they have learned. In teaching, combined with the class
Some thinking questions after practice lead students to start thinking, solve problems independently and master scientific and flexible methods. Assign some interesting homework, such as hands-on homework, less rigid exercises.
5. Strengthen the connection between family education and school education, communicate with parents in time, and let parents guide their children to learn in a correct and appropriate way.
6. Further cultivate students' interest in learning mathematics and good study habits, fully tap various online teaching resources, make good use of various teaching media, organize students to carry out colorful learning activities, and first attract students from the content and form of learning. Guide students to develop the inherent qualities of independent thinking, daring to ask questions, being good at listening and being willing to express.
7. Continue to strengthen the connection between family education and school education, and appropriately teach parents some correct methods to guide their children's learning. Do a good job in transforming underachievers and promoting outstanding students.
