National Mathematics Mathematics Book 6

I. Analysis of textbooks: The textbook includes the following contents: a factor is a two-digit multiplication, divisor is a two-digit division, year, month, and day of recognition, mixed operation and set of questions. A factor that is a two-digit multiplication and a divisor that is a two-digit division is the focus of this book. Students master the two parts of the calculation, which lays a good foundation for learning the fractional multiplication and division in the future. Mixed computing and application questions are also a focus of this volume. This part of the content is based on the previous volume, continue to learn the mixed operation sequence of the three-step problem, continue to learn some of the two-step calculation of the application. By answering the applied questions, students will further understand and master some quantitative relationships, improve their ability to use the knowledge they have learned to analyze and solve practical problems, and develop students' skills and habits to check the answers. In terms of the measurement of quantity, the textbook of this book further expands the scope of measurement knowledge on the basis of the previous volume, and teaches the larger time unit year, month, day and 24 o'clock time method. Second, the analysis of the situation: A factor is a two-digit and divisor is a two-digit multiplication, division is the focus of this volume. Although students have learned that a factor is a number and the divisor is a multiplication and division of a single number, with a certain foundation, but begin to learn a factor is a two-digit and divisor is a two-digit multiplication, the division still has Some difficulties. When learning to multiply by two digits, the writing position of each partial product is often unclear for the order of multiplication. When learning to divide by two digits, it is better to try to get the exact quotient and the method of division than to use one digit. In order to better cultivate and improve the students' ability to analyze and answer the set questions, the textbooks in this book are based on the students' existing experience in the two-digit multiplication, division and multiplication, respectively. Common quantitative relationships, such as unit price, quantity and total price relationship, speed, time and distance relationship. These quantitative relationships are important basic knowledge for further study. Initially grasping some quantitative relationships not only deepens the understanding of various daily numbers and mutual relations, but also develops the ability of students to abstract their abstracts and raises the level of thinking in the process of solving problems. Third, the teaching requirements: 1, to enable students to master a factor is a two-digit and divisor is a two-digit multiplication, division of the algorithm, can be more skillful to calculate a factor is a two-digit multiplication and divisor is two The division of numbers, master the method of checking the multiplication and division, and develop the habit of checking. 2, to make students more proficient in the calculation of a single digit by two digits and the corresponding division, a factor and division is the multiplication and division of the whole ten. 3. Make the students know the time unit year, month and day, and know the number of days in each month and year, and use the 24-hour time method to express the time. 4. Make the students master the four mixed operation sequences, be able to calculate the general three-step questions more skillfully, and answer the two-step calculation of the text questions and the two-step application questions. Fourth, teaching measures: 1, efforts to study textbooks, conscientiously study the syllabus, strengthen their own learning, and constantly improve their own quality. 2. Praise the advanced, encourage poor students, actively mobilize the enthusiasm of students, and balance the development of the whole class. 3. Pay attention to the image and intuitive teaching. Cultivate students' observation ability and thinking ability, and consciously develop students' ability to analyze and reason. 4. Strengthen regular training, strengthen oral calculation training, and improve oral calculation skills. 5. Appropriate distribution of operations, and careful correction and timely revision. 6. Sub-unit, phase-by-stage acceptance of student learning effects, timely discovery of problems and resolution of five, class schedule: slightly. . . [1]
