Summary of the review plan of the fourth grade mathematics volume 2 of Beijing Normal University Edition 1. Teaching content and purpose requirements of this semester
(a) Number and Algebra field
1. Unit 1 "Understanding and addition and subtraction of decimals". On the basis of learning "Yuan, Angle, Minute and Decimal" in the second volume of Grade Three, the understanding of decimals is expanded, and decimals are initially linked with fractions to further understand the meaning of decimals. Combined with the specific situation, learn the mixed operation of decimal addition and subtraction and addition and subtraction, use decimal addition and subtraction to solve some problems in daily life, and feel the close connection between decimal and real life.
Unit 3 "fractional multiplication" Combined with specific situations, let students understand the significance of decimal multiplication, experience the process of exploring the calculation method of decimal multiplication, master the calculation method of decimal multiplication, and use decimal multiplication to solve simple problems in life.
Unit 5 "Fractional Division". This unit includes decimal division, product quotient approximation, cyclic decimal, decimal elementary arithmetic, etc. Combined with the specific situation, I experienced the process of exploring the calculation method of fractional division and experienced the mathematical thought of reduction. Understand that sometimes in life, you only need to ask for the approximate value of the product quotient, master the method of finding the approximate value, and cultivate the consciousness of estimation. Have a preliminary understanding of cyclic decimals, and use four decimal operations to solve simple problems in daily life.
Unit 7 "Cognitive Equation". Let students understand that numbers can be represented by letters in combination with life scenes. Understand the equation preliminarily through intuitive teaching AIDS; Through game activities, we can get a preliminary understanding of the properties of the equation, and we can use the properties of the equation to solve simple equations.
(b) "Space and Graphics" field
1. Unit 2 "Understanding Graphics". Sort out some figures learned through classification activities; Through the classification of triangles, we can understand the characteristics of various triangles; Through calculation, it is found that the sum of the degrees of the three angles of the triangle is equal to 180 degrees, and the sum of any two sides of the triangle is greater than the third side. Further understand the characteristics of parallelogram and trapezoid; Will use the learned graphics to design some simple patterns.
2. Unit 4 "Observing Objects". Be able to identify the pictures taken by different observation points of high and low, far and near and their sequence; Through practical observation, students can realize that the same scene is in different positions and the pictures they see are different; Be able to identify photos taken from different locations and their sequence.
(c) "Statistics and Probability" field
Unit 6 "Fair Play". Through games, students can experience the possibility and fairness of the rules of the game. Can design fair and simple rules of the game.
"Comprehensive application" field
In the teaching content of each unit, this textbook is equipped with practical problems and practical activities, and the presentation form is real and interesting. In addition, three special activities were arranged, namely "Knowledge in Numbers", "Passion Olympics" and "Laws in Numbers", to enable students to comprehensively apply what they have learned to solve practical problems.
(5) sorting out and reviewing
Including review (1), review (2) and general review.
Second, the teaching objectives of this semester
1, so that students can know natural numbers and integers, master the counting method of decimals, and read and write three-level multi-digits correctly according to the series of numbers.
2. Make students understand the meaning of four integer operations and master the relationship between addition, subtraction, multiplication and division.
3. Make students master the operation rules of addition and multiplication, and use them in some simple operations to further improve the oral calculation of integers.
4. Make students understand the meaning and nature of decimals, and skillfully perform written calculation and simple oral calculation of decimals.
5. Make students know the simple method of data arrangement and the simple statistical chart, and understand the meaning of the average, and they will find the simple average.
6. Make students further master the elementary arithmetic order, calculate the general three-step calculation problems more skillfully, and use brackets to solve some easy three-step calculation problems.
7. Enable students to solve some application problems of two-step calculation with slightly complicated quantitative relationship, solve some relatively easy application problems of three-step calculation, and learn the examination method initially.
8, combined with the relevant content, to further cultivate students' inspection habits, patriotism education and dialectical materialism education.
Third, the class situation analysis
The school has good teaching conditions, strong teachers and advanced teaching facilities, and has modern teaching equipment such as electric classroom, language lab, microcomputer room and multimedia classroom. Most students have good family conditions and relatively high quality. In particular, students have experienced nearly four years of curriculum reform experiments and become the beneficiaries of curriculum reform. The students in this class have high learning enthusiasm and strong learning ability. There are three students in class * * *, most of whom can gain knowledge from their existing knowledge and experience. The level of abstract thinking has developed to a certain extent, the basic knowledge is firmly grasped, and the students have certain mathematics learning ability. Individual students have poor basic knowledge. Not interested in mathematics, passive in learning, not listening carefully in class, unable to finish homework on time, and having difficulties in learning, especially in the quantitative relationship analysis of application problems. There are also some students who are smart, but they don't study hard and their grades are not ideal.
Fourth, specific teaching measures
1. Strengthen ideological education and learning purpose education so that students can further correct their learning attitude.
2. Take students as the main body, advocate heuristic teaching, pay attention to trial teaching and stimulate students' curiosity.
3. Pay attention to classroom teaching reform, use various methods to arouse students' enthusiasm, require homework to be completed in the classroom, and give timely feedback.
4. Do a good job in counseling underachievers, implement the method of "making up lessons in class" and organize mutual learning.
5. Cultivate students' analytical ability, comparative ability and comprehensive ability.
6. Cultivate students' abstract generalization ability.
7. Cultivate students' ability of migration and analogy.
8. Cultivate the flexibility of students' thinking.
I recommend it carefully.
