Teaching plan of the second volume of fourth grade mathematics
First, the analysis of learning situation
There are 34 students in this class. Most of them are good at learning routines, like learning mathematics, and can gain knowledge from 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. I'm not interested in mathematics, I'm passive in learning, I don't listen carefully in class, my homework can't be finished on time, I have difficulties in learning, especially the quantitative relationship analysis of application problems, so my grades are not ideal. This requires teachers to pay more attention to teaching students in accordance with their aptitude while facing all students in teaching.
Second, the teaching content and analysis
The teaching contents of this textbook include: understanding decimals, addition, subtraction, multiplication and division of decimals, understanding triangles, parallelograms and trapeziums, observing objects, playing fair games, and understanding equations.
(a) Number and Algebra field
1, unit 1 "Understanding and addition and subtraction of decimals". Including the meaning of decimal, the mixed operation of decimal addition and subtraction, and the problems solved by decimal addition and subtraction.
Unit 3 "decimal multiplication" Including the significance of decimal multiplication, the calculation method of decimal multiplication, decimal multiplication to solve simple problems in life.
Unit 5 "Fractional Division". Include fractional division calculation method, approximate method of product quotient, cultivation of estimation consciousness, cyclic decimal, decimal elementary arithmetic, etc.
Unit 7 Understanding Equation. Including letters can represent numbers, understand equations and their properties, and solve simple equations with the properties of equations.
(b) "Space and Graphics" field
1, Unit 2 "Understanding Graphics". Sort out some learned graphics; The classification of triangles and the characteristics of various triangles; The sum of degrees of three angles of a triangle, and the sum of any two sides of the triangle is greater than the third side; Further understand the characteristics of parallelogram and trapezoid; Simple design pattern.
2. Unit 4 "Observing Objects". Includes identifying photos taken from different positions and their sequence; Realize that the same scene is in different positions and the picture you see is different.
(3) The field of "Statistics and Probability": Unit 6 "Game Fairness". Experience the fairness of the rules of the game and design fair and simple rules of the game.
(4) The field of "comprehensive application": In each unit, this textbook is equipped with practical problems and practical activities with realistic themes and diverse and interesting presentation forms. 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) Arrangement and review: including arrangement and review (1), arrangement and review (2) and general review.
Third, the teaching objectives
1. Expand the understanding of decimals, initially connect decimals with fractions, and 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.
2. Combining with specific situations, make students understand the significance of fractional multiplication and division and experience the exploration of fractional multiplication.
And master the calculation method of fractional multiplication and sum, understand that sometimes only the approximate value of product quotient is needed in life, master the method of finding approximate value, and cultivate the awareness of estimation; Have a preliminary understanding of cyclic decimals; Using the knowledge of decimal multiplication and division to solve simple problems in life.
3. Let students understand that numbers can be represented by letters; Have a preliminary understanding of the equation and its properties, and can use its properties to solve simple equations.
4. Through classification activities, students can further understand the characteristics of triangles, parallelograms and trapeziums; 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. Will use the learned graphics to design some simple patterns.
5. Combined with the specific situation, I experienced the process of exploring the calculation method of fractional division, and initially realized 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.
6. Through practical observation, students realize that observing the same scene in different places will produce different pictures. Be able to identify the corresponding photos taken from different positions and their sequence; Be able to identify the corresponding photos and sequences taken from the height and distance of the observation point.
Through games, students can experience the possibility and fairness of the rules of the game. Can design fair and simple rules of the game.
Fourth, the difficulties in teaching
Teaching emphasis: understanding decimal, addition, subtraction, multiplication and division; Classification of graphics. Difficulties in teaching: mastering four decimal arithmetic methods.
Verb (abbreviation of verb) teaching measures
1. Strengthen purposeful education in learning, fully tap students' potential and give full play to students' main role. 2. Enhance students' practical ability and cultivate students' spatial concept.
3. Stimulate students' interest in learning mathematics, create more learning situations, boldly let students learn by themselves, solve problems and develop students' personality.
4. Pay attention to cultivating students' thinking flexibility and innovative consciousness; Pay attention to strengthen the connection between mathematics and real life, so that students can solve mathematical problems in life and feel, experience and understand mathematics.
5. Pay attention to let students participate in group cooperative learning and cultivate students' awareness of cooperation and communication.
6. Strengthen individual counseling, especially for students with learning difficulties, pay more love, appropriately reduce homework requirements, and strive to improve their grades.
