Jiangsu Education Press, Grade 2, Volume 2, Work Plan of Mathematics Teaching Part I, Analysis of Classroom Situation
There are 92 students in two classes in Grade Two. After a year and a half of mathematics study, they basically achieved their learning goals in basic knowledge and skills. They are interested in learning mathematics and are willing to take part in learning activities. Especially some hands-on, cooperative learning content is more interested. However, when encountering problems that are difficult to think deeply, there is a retreat. Although the child did well in the final exam last semester, the results did not represent the whole situation of his learning mathematics. Only in the classroom and mathematics learning activities can the real situation of a child's learning be fully reflected. Therefore, for these students, I should pay more attention to maintaining the interest that has basically formed, and gradually let students successfully experience the fun they get in thinking.
Second, the teaching content
The teaching contents of this book are as follows: Unit 1: Understanding numbers within 10,000; Understanding of meter, decimeter and millimeter; Unit 3 Addition and subtraction of numbers within ten thousand (1); Unit 4 Graphics and Assembly; Unit 5 Addition and subtraction of numbers within ten thousand (2); Unit 6 Mixed operation; Unit 7 Statistics; Unit 8 multiplies two or three numbers by one number; Unit 9 Understanding of Time, Minute and Second; The perimeter of the cell 10 graph; Unit 1 1 is reviewed frequently.

Fourthly, the difficulties in teaching.
Understanding and comparison of numbers within 10,000 in Number and Algebra; The diversity of calculation methods, remainder division and addition and subtraction of numbers within ten thousand are the key teaching contents. Understanding and transformation of kilometer, decimeter and millimeter, understanding symmetry phenomenon and understanding the characteristics of rectangle and square are the key teaching contents in Space and Graphics. In statistics and probability, subsection statistics is the key teaching content.
In the teaching of Space and Graphics, it is difficult to understand the spatial concepts of kilometers, decimeters and millimeters and the conversion between units. It is a difficult point in teaching to make students understand the symmetry phenomenon in life. The conversion between hours, minutes and seconds is a difficult point in teaching.
In the part of "Statistics and Probability", the form and method of subsection statistics are the difficulties in teaching.
Five, the specific measures of teaching
1. Stack the knowledge of "Number and Algebra" into a knowledge block to teach. Follow the principle of easy to difficult to teach. Strengthen students' oral expression ability. Take the form of quick calculation before class, calculation while listening, and mutual examination by opponents.
2. In the course of "Space and Graphics", students' spatial imagination can be cultivated with the help of physical objects. In the process of exploration, students' ability of observation and operation has been improved, and the initial concept of space has been developed. Design various exercises and games according to the age characteristics of students.
3. In Statistics and Probability, you can take the data around students as statistical data, guide students to make statistics in stages according to the sequence of events, and gradually learn statistical methods. Make full use of learning tools to make students fully understand what they have learned and cultivate their practical ability.
4. Get in touch with students' real life and learn what they have learned. For example, know the number within 10 thousand. Ask students to collect the prices of some items on some leaflets in the supermarket, deepen their understanding of three or four digits, and embody the truth that mathematics comes from life.
5. Increase practical activities to cultivate students' consciousness of applying mathematics. Combine the mathematical knowledge in this book to strengthen the cultivation of ability and good study habits.
Analysis of Students' Knowledge Mastery in Part 2 1 of Mathematics Teaching Work Plan for Grade Two of Jiangsu Education Press.
There are 65 students in this class, including 35 boys and 30 girls. The students in the class have a good learning foundation, but they have poor awareness of class participation, lack of enthusiasm for learning, and have not formed good study and homework habits. The construction of study style and class spirit needs to be further strengthened. A few students are biased, selfish and narrow-minded. Most students are healthy, but a few students are poor, so we should strengthen physical exercise.
