First, the analysis of learning situation
There are 0/9 students in this class, including 0/5 boys and 4 girls. The problems after my class took over this class: there are many boys and poor discipline; Study habits, don't attend classes, dare not answer questions loudly; Finish homework on time and so on. In terms of grades, the students in the class set have poor grades; There are few top students; Poor mathematical calculation ability, sloppy, not fond of thinking and analyzing problems.
Second, teaching material analysis and teaching
This textbook has nine units. The unit arrangement and main contents in the four fields of number and algebra, space and graphics, statistics and probability, and practical activities are as follows:
(a) Numbers and algebra
● Understanding of numbers
1. In the scenario, the decimal counting method will use "10,000" and "100 million" to represent large numbers.
2. Feel the meaning of large numbers in real situations and estimate them.
3. Understand the role of numbers in daily life, express things with numbers and communicate with each other.
4. From the natural number of 1- 100, we can find the characteristics of all multiples of a number in 10 and multiples of 2, 3 and 5.
5, in the natural number 1- 100, you can find all the factors of a certain number.
6. Odd, even, prime and composite numbers.
Low numerical operation
7. You can multiply (or divide) two digits within 100 by one digit. The content comes from www.hbban.cn
8. You can calculate the division of three digits divided by two digits.
9. With the help of calculator, you can solve simple problems and simple mathematical rules.
(b) space and graphics
● Understanding of graphics
1, two points, a straight line and two intersecting straight lines.
2, can distinguish between straight lines, line segments and rays.
3. Experience is that the line segment between two points is the shortest, until the distance between two points.
4. Know the concept of fillet and flat angle and the relationship between fillet, straight angle, obtuse angle, right angle and acute angle.
5, life scene, the parallel and intersecting (including vertical) relationship between two straight lines on the plane.
● Measurement
6. I will use a protractor to measure the specified angle, draw an angle of a specified degree, and draw an angle of 30, 45, 60, 90 with a triangle.
7. The volumes of "liter" and "ml" are called 1 liter = 1000 ml.
(3) Statistics and probability
● Simple statistical process of data
1. Experience the process of collecting, sorting, analyzing and describing simple data (use a calculator if necessary). Haohebei education network
2, example, know the bar chart (one grid represents multiple).
3. The data can be represented intuitively and accurately by bar charts.
4, can consciously obtain data information from newspapers, magazines, television and other media, and can read bar charts.
(4) Comprehensive application
1, with comprehensive experience in solving simple problems and confidence in applying mathematics to solve problems.
2, comprehensive application of knowledge to solve simple problems, experience and methods.
3, feel the knowledge of mathematics, understand the role of mathematics.
Third, the main teaching measures
1, the creation of teaching scenes, paying attention to students' life experience, new perceptual materials, students' operational activities, and mathematics concepts that life helps students.
2. Cultivate students' estimation consciousness and ability.
3. Let students learn the effectiveness of calculation and teaching by solving problems.
4. Use the "transfer" teaching method to cultivate students' ability to draw inferences from others.
5, students think independently, cooperate and communicate, so that students can experience the fun of inquiry. Appropriate and timely use of cooperative learning to cultivate students' application awareness and problem-solving ability.
6, intuitive teaching, the role of teaching AIDS and learning tools.
7. Pay attention to students' understanding of the calculation process and methods, grasp the difficulties, and let students lay a good foundation of knowledge.
8. Let students go through the process of guessing, experimenting and verifying to construct mathematical knowledge.
In short, in the new semester, I will closely focus on the center of classroom teaching reform, with the new curriculum as the driving force and scientific research as the starting point. Facing the east wind of the new curriculum, we will bravely climb the peak along the established course and create new glory in educational reform.
