Jiangsu Education Press Grade Three Mathematics Teaching Plan Part II
First of all, a brief analysis of the teaching materials. The third grade (the second volume) of Mathematics, a standard experimental textbook for compulsory education, published by Jiangsu Education Press, still arranges the teaching contents in four regions. In the field of numbers and algebra, continue to teach division and multiplication of integers, including three digits divided by one digit and two digits multiplied by two digits, and apply these calculations to solve practical problems; Continue to teach fractions, average the whole composed of several objects, and express one or several of them with fractions; Teaching decimals for the first time, I have knowledge of the meaning of one decimal, reading and writing, size comparison, addition and subtraction calculation, etc. It also teaches the time unit year, month and day, the greater length unit kilometer and the greater mass unit ton. In the field of "space and graphics", the phenomenon of translation and rotation and the method of translating graphics on square paper are taught; The initial teaching of axisymmetric graphics: continue to observe simple geometric graphics from the front, side and top, and express the shapes you see with graphics; The meaning of teaching area, the commonly used area units, and the area calculation formulas of rectangles and squares. Teach the meaning of average value in the field of statistics and probability, find the method of average value of a group of data, and describe and analyze the basic situation of a group of data with average value. Combined with the teaching contents of the above three fields, six practical activities were arranged. "Our experimental field" is a situational activity that puts forward and solves practical problems related to mathematics. "Exercise and physical changes" is a special research activity that uses statistical knowledge and methods to study pulse and respiratory changes caused by exercise. Others are operational (production) activities.
In addition, there are more than ten "Do you know", which are roughly divided into two categories. One is knowledge of nature and social knowledge related to mathematical knowledge, such as the temperature standard for dividing the four seasons of the year, the symmetry phenomenon in nature and architecture, and the weight of objects on the moon is only on the earth. The second category is the historical stories about mathematics, such as the multiplication calculation of "Dijin" in Ming Dynasty, tools for measuring the length and weight of objects in ancient and modern times, geometric figures on unearthed cultural relics, and ancient methods for expressing decimals. These contents can broaden students' horizons, increase their knowledge and stimulate their enthusiasm for mathematics and learning mathematics. More than ten thought questions are arranged as flexible teaching content to meet the needs of some regions and students.
Second, the characteristics of textbook arrangement
1, providing realistic problem situations, allowing students to discover and put forward new calculation problems, thus creating a realistic need to learn new calculation methods. Through a series of scenarios, students can constantly discover and ask new questions in interrelated situations, which is helpful for students to understand the close relationship between computing and life and inspire students to use existing knowledge and experience to solve problems; Pay attention to introducing concepts with examples and helping students to establish concepts such as area and area unit, and help enrich concepts with different examples.
2. Show the real situation, and gradually deepen the understanding of the meaning of fractions through intuition and operation, which can reduce the difficulty of students' understanding, help students to gradually deepen their understanding of the meaning of fractions, and arrange many intuitive operation activities to help students gradually raise their specific perception to mathematical conclusions; Highlight the relationship between decimals and life, decimals and fractions, pay close attention to students' real life in teaching materials, pay attention to the communication between decimals and fractions, and promote students to form a good decimal consciousness.
3. Pay attention to the comparison of mathematical knowledge. First, through comparison, let students experience calculation methods, discover calculation rules, generate new experiences and improve calculation ability; Second, through comparison, help students master the connection and difference between area and perimeter. For example, by putting together, calculating and listing, let students realize that some figures have the same area, but their perimeters are different. On the contrary, some figures have the same perimeter, but their areas may be different. In this way, students will gradually understand the concept and calculation method of graphic area and perimeter under specific circumstances, and be promoted.
4. Translation, rotation and axial symmetry are all methods to transform graphics. When arranging teaching materials, we should pay attention to selecting materials that students are familiar with and interested in, so as to attract students' attention and stimulate their enthusiasm for actively participating in learning activities. Design various operation activities, so that students can gradually deepen their experience in the operation; Combine observation and operation activities to guide students to appreciate and make beautiful patterns, so that students can acquire mathematical knowledge, be influenced by beauty and cultivate positive and healthy aesthetic taste.
5. Mathematical practice highlights the integrity, reality and application of mathematical knowledge. One is to emphasize the connection and integration of mathematical knowledge in different fields. For example, after knowing the time unit "year, month and day", we arranged the "birthday quick day" practice, sorted the birthdays of middle school students by month and quarter respectively, and completed statistical charts and tables, so that the knowledge of "year, month and day" was organically combined with the knowledge of "statistics", which reflected comprehensiveness. The second is to emphasize the connection with students' real life. For example, after understanding "kilometers and tons", arrange practical activities of "understanding kilometers" to guide students to understand kilometers from different angles and experience the wide application of kilometers in life by consulting sports, transportation, astronomy, geography and other related knowledge. Third, emphasize the comprehensive application of what you have learned to solve problems. For example, after learning the "Statistics" unit, the practical activity "Exercise and Body Change" is always focused on researching and solving problems, thus highlighting the application of mathematical knowledge.
Third, teaching suggestions
1, prepare necessary teaching AIDS and learning tools. Teaching AIDS should be prepared for the teaching content in the fields of space and graphics, as well as for the creation of situations in other fields and the reproduction of real life materials. We should make full use of the situations provided by textbooks to stimulate students' enthusiasm for learning. Teachers' teaching AIDS should be ready, and every student can prepare the necessary learning tools so that students can fully observe and operate activities.
2. Accurately grasp the teaching requirements. First, we should accurately grasp the degree of teaching content, and we should not artificially increase the difficulty and density of teaching and increase the learning burden of students, and vice versa; Second, we should respect students' individual differences, allow students to try, practice and revise repeatedly, and encourage students to help each other and cooperate to complete tasks.
3. Pay attention to the development of students' estimation strategies and cultivate students' estimation consciousness and ability; Pay attention to ask students to calculate first and then check and check, and cultivate students' good checking habits.
4. When solving problems, we should first encourage students to think independently, let them make use of existing knowledge, methods and experience, experience the process of exploration, and then fully communicate, so as to cultivate students' application consciousness and the habit of careful observation and positive thinking.
5. Strengthen the design of exercise questions, strive for various forms, novel and flexible questions, avoid single, boring, repetitive and mechanical training, be precise and concise, and let students communicate with each other in practice, so that they can exchange some relevant information and accumulate feelings. When solving problems, we should pay attention to comparison, communicate the links between some practical problems and form a good cognitive structure. After solving the problem, students can talk about their own ideas and develop mathematical thinking. In the teaching of thinking problems, students should be guided to explore their own solutions on the basis of understanding the meaning of the problems, rather than teaching them as examples.
6. Pay attention to the evaluation of teaching. When evaluating students' mathematics learning, we should not only pay attention to the understanding and mastery of knowledge and skills such as multiplication and division, but also pay attention to the evaluation of students' independent exploration, cooperation and exchange in the learning process, and pay attention to the formation and development of students' positive feelings and attitudes towards learning mathematics. There are various evaluation methods, so we should grasp the opportunity of evaluation, guide and enhance students' self-confidence in learning mathematics, stimulate students' interest in learning and continue for the future.
