Through general review, students can systematically sort out and review what they have learned this semester, further consolidate the concept of numbers, improve their ability to calculate and solve problems, develop the concepts of space and statistics, gain successful experience in improving their own mathematical ability, and fully achieve the teaching objectives set this semester.
1. Check for leaks and fill gaps. By reviewing and practicing the basic knowledge, students' memory is strengthened, their understanding is deepened, and what they have learned is internalized into knowledge literacy. Enable students to grasp and understand knowledge from perceptual knowledge to rational knowledge.
2. Solve problems flexibly and improve the ability of comprehensive application and solving practical problems. In the process of reviewing and practicing, students can classify and sort out knowledge, help students find out the relationship between knowledge and the law of solving problems, re-integrate and form a complete knowledge system. By analogy, I can comprehensively and flexibly use what I have learned to solve simple practical problems and have strong mathematical application ability.
3. In the process of reviewing and practicing, we should pay attention to cultivating students' learning methods, mathematical consciousness and mathematical thinking, and develop students' logical thinking ability.
4. Cultivate students' good study habits of doing problems and checking carefully, and form good mathematical sentiment.
Second, review content:
1, Numbers and Algebra
Unit 1, Understanding of Large Numbers
Unit 3, Three Numbers Multiply Two Numbers
Unit 5. The division of divisor is a two-digit number.
2. The second unit of graphic geometry, the fourth unit of angle measurement, parallelogram and trapezoid.
3. Statistics and Probability Unit 6, Statistics
4. Mathematical thinking method unit 7. Mathematical wide angle (reasonable arrangement)
Third, review objectives:
1. Have a further understanding of tens of thousands and hundreds of millions of numbers, decimal counting method, expressing large numbers in tens of thousands and hundreds of millions, divisor, rewriting and other knowledge, and establish a cognitive structure about the concept of integers;
2. Further consolidate the written division calculation with divisor of two digits, further improve the operation skills of calculating large numbers and exploring laws with calculators, and deepen the understanding of calculators;
3. Mastering the characteristics of straight lines, rays and line segments, and knowing the angle, we can draw parallel lines and vertical lines correctly (a point outside the straight line and a point on the straight line), and further develop the concept of space;
4. Through sorting and reviewing, students can further master the basic knowledge and methods of statistics, and can sort out and make statistical charts according to the given data and analyze the results.
5. By sorting out and reviewing, students can further improve their ability to solve practical problems by comprehensively applying what they have learned, and further realize the value of mathematics in the process of solving practical problems.
6. Through sorting and reviewing, let students experience the review of their learning situation this semester and the process of combing the knowledge and learning methods they have learned, so as to stimulate students' desire for active learning and further cultivate students' reflective consciousness and ability.
IV. Specific measures for review:
"Understanding of Large Numbers"
1. Review related knowledge such as numbers, series, counting units and decimal counting methods by using the numerical sequence table, so that students can further master these basic concepts.
2. Review the reading rules, focusing on how to read numbers with zeros in the middle and at the end, and then complete the general review question 1.
3, review the writing methods, but also focus on how to write the numbers with 0 in the middle and at the end, and then complete the general review of the second question.
4. Review the method of rewriting large numbers into numbers in units of "10,000" or "100 million", and use the "rounding" method to find the approximate number to complete the general review questions 3 and 4.
(2) "multiplication and division method"
1, review the oral arithmetic of multiplication and division, and combine the relationship between factor and product, the changing law of quotient with oral arithmetic of multiplication and division, so that students can further understand oral arithmetic and use these laws flexibly to make oral arithmetic more correct and fast. Complete general review questions 5 and 8.
2. Review the written multiplication and division method. Let the students talk about the problems that should be paid attention to in the written multiplication and division, such as what should be paid attention to in the multiplication with 0 in the middle and at the end of the factor, and what is the principle of division, trial quotient and quotient adjustment. , and then complete the general review of questions 6 and 7.
3. Review how to solve simple practical problems by multiplication and division. Through review, students can understand the necessity of estimation in solving problems and realize the diversity of estimation strategies. Complete the general review questions 9 and 10.
(c) "Space and graphics"
1. Make proper systematic arrangement, so that students can clearly understand the concept of each graph, understand the connections and differences between graphs, and learn to describe the characteristics of various graphs in mathematical language.
2. Draw the relationship of various graphs with diagrams, so that students can see it more intuitively and clearly. Then complete the general review questions 1 1 and 12.
(4) "Statistics"
Review the connection and difference between composite bar chart and single bar chart, and the matters needing attention when drawing composite bar chart. Complete the general review questions 13.
