First, the analysis of learning situation

Judging from the final exam results of the first volume of the seventh grade mathematics, the excellent rate of this class has exceeded 10, which can be regarded as the expected goal, but the passing rate has only reached more than 43%, which is still far from the expectation. Generally speaking, although most students study hard and master some methods and skills of learning mathematics, the lack of solid basic knowledge has become a bottleneck restricting their study, leading to unbalanced class development and serious polarization.

Second, the guiding ideology

Adhere to the educational policy of the 17th National Congress of the Communist Party of China, and implement the new curriculum reform based on the new curriculum standard of junior high school mathematics. Taking improving students' basic knowledge and skills as the fundamental task, we should formulate practical teaching plans and pay attention to cultivating students' innovative thinking and applied mathematics ability. Through this semester's mathematics teaching, students' interest in learning mathematics is further cultivated and their thirst for knowledge is stimulated. At the same time, complete the mathematics teaching task of the second volume of the seventh grade.

Third, the teaching objectives

Knowledge and skill goal: learn parallel lines, master the drawing method of plane rectangular coordinate system, learn the solution of binary linear equations, inequalities and inequality groups, and be able to draw simple statistical charts. At the same time, further improve students' geometric drawing ability. Process method goal: learn to observe and analyze geometric figures, find the relationship between the characteristics of figures and figures, and learn to sum up laws. Initially establish the idea of equations, and learn to express the relationship between quantities with algebraic expressions. Attitude and emotional goals: Know life, feel life, and understand that mathematics serves life. Class teaching goal: excellent rate:15%; Qualified rate: 50%.

Fourth, teaching material analysis.

Chapter 5, Intersecting Lines and Parallel Lines

This chapter mainly discusses the positional relationship between two straight lines in the same plane: ①, intersection ② and parallelism on the basis of the fourth chapter "Preliminary Understanding of Graphics". This chapter focuses on the concept of vertical line and the determination and properties of parallel line. Difficulties in this chapter: the idea, steps and format of proof, the nature of parallel lines and the application of judgment.

Chapter 6, Plane Cartesian Coordinate System

The main content of this chapter is the plane rectangular coordinate system and its simple application. This chapter focuses on the understanding and establishment of plane rectangular coordinate system and the determination of point coordinates. Difficulties in this chapter: the determination of coordinates and points in the plane rectangular coordinate system.

Chapter VII, Triangle

This chapter mainly studies the sum of line segments, angles and internal angles of polygons related to triangles. This chapter focuses on the properties and applications of the sum of internal angles of triangle segments, angles and polygons. Difficulties in this chapter: correctly understand the properties of the height, midline and bisector of a triangle, draw and prove the sum of the internal angles of the triangle, and explore the sum of the internal angles of the polygon.

Chapter 8, Binary linear equations.

This chapter mainly studies the concept, solution and application of binary linear agenda (group) and its solution. This chapter focuses on the solution and practical application of binary linear equations. Difficulties in this chapter: enumerate binary linear equations to solve practical problems.

Chapter 9, Inequalities and Unequal Groups

The main content of this chapter is the solution and simple application of one-dimensional linear inequality (group). This chapter focuses on the basic properties of inequality and the solution and simple application of one-dimensional linear inequality (group). Difficulties in this chapter: understanding and application of basic properties of inequalities, listing linear inequalities (groups) to solve simple practical problems.

Chapter 10, data collection, collation and description

This chapter mainly studies the collection, collation and analysis of data, and makes a correct description of the respondents according to the data. This chapter focuses on the significance, characteristics and classification of the survey, and describes the data with fan chart, frequency distribution histogram and frequency disconnection chart. Difficulties in this chapter: drawing statistical charts of data and how to use various statistical charts to make a correct description of the respondents.

Fourth, teaching measures.

1, study the new curriculum standard seriously, study the teaching materials, select exercises, prepare lessons carefully, do a good job in teaching the new curriculum. At the same time, carefully correct homework, give good guidance, find problems and solve them in time, and conscientiously sum up the experience and reasons of success or failure.

2. Make full use of modern teaching facilities to make teaching props, set up teaching situations, and combine daily life step by step. Guide students to actively participate in classroom learning and discussion, and actively participate in the exploration of knowledge and the summary of laws.

3. Create a democratic, harmonious, equal and independent learning atmosphere, and guide students to explore, communicate and share the joy of discovery. So as to realize the fun of learning and stimulate students' enthusiasm for learning.

4. Carefully design the theme of inquiry, guide students to learn divergent thinking, cultivate students' creative thinking ability, and realize multiple solutions to one problem, draw inferences from others and draw inferences from others.

5. Carry out hierarchical teaching mode, set up mutual learning groups, and promote the future with excellence. At the same time, pay close attention to middle school students, coach underachievers and make progress together.

Five, the schedule

Please make an appropriate class plan according to your actual teaching situation and students' learning situation.
