There are 5/kloc-0 students in Grade Three, including 28 boys and 33 girls. Basically, students' habits in study, work and rest have become formalized. However, because students come from different families, parents' educational level and moral quality are quite different. Therefore, some students' study habits and behavior habits are poor. Most students just stay in class and listen attentively, lacking the consciousness and habit of active participation. Some students are lax in class discipline, like to talk at will, refuse to finish their homework on time, and like to drag their homework.

Therefore, this semester, in view of these characteristics, mathematics classes should not only be rich in content, diverse in forms and attractive; Moreover, it is necessary to cultivate students' interest in learning mathematics and let them participate in it, so as to strengthen students' confidence in learning mathematics well, enhance students' willpower and develop good study habits. To this end, the plan for this semester is as follows:

Second, teaching objectives: knowledge and skills.

1. In oral calculation, I can calculate the whole hundred divided by the number of lesson plan channels in China Education Universal Network (quotient is whole hundred or whole ten), the easier hundred divided by one digit, and the easier two digits multiplied by the whole ten digits.

2. Written calculation: it will calculate three digits divided by one digit (including the case that there is a 0 in the middle and the end of the quotient) and two digits multiplied by two digits (including the simple vertical calculation of multiplying two digits by an integer of ten), and it will calculate the addition and subtraction of a decimal.

3 estimation: the quotient of three digits divided by one digit is several digits, and the product of two digits multiplied by two digits is estimated. Can tell the process and method of estimation.

4 A preliminary understanding of a score or a whole score, a preliminary understanding of a meter's score is a few tenths of a meter, and a few horns are several tenths of a yuan.

5 can understand the meaning of a decimal place according to the specific situation, read and write a decimal place and compare the size of two decimal places.

Know the year, month and day, distinguish the big month from the small month, judge the normal year and leap year, and calculate the number of days in a quarter, half a year and the whole year.

7. Understand the meaning of area with examples. Knowing the square centimeter, square decimeter and square meter of the lesson plan channel of China Education Universal Network, we can choose the appropriate area unit to estimate, measure and express the graphic area. Explore and master the area formulas of rectangles and squares, and calculate or estimate the related areas. Knowing the forward speed between every two adjacent units of square centimeter, square decimeter and square meter, simple unit conversion will be carried out.

8. Understand the meaning of the average with examples. Will find the average of a set of simple data (the limit result is an integer). Will use the average to describe the situation of a set of data. The average value will be used to compare and analyze the two sets of data.

Emotions and attitudes:

1. Understand the content of mathematics in real situations, use the mathematical knowledge you have learned to solve practical problems around you, gain successful experience, and enhance your confidence in learning mathematics well.

2. Under the organization and guidance of teachers, we can acquire mathematical knowledge through our own active exploration, and initially develop innovative consciousness and practical ability.

3. Learn more about mathematics through the "Do you know" column in the textbook, and realize that mathematics is a method and theory gradually formed by human beings in their long-term life and labor, and is the crystallization of human civilization. Understanding mathematics is closely related to the development of human history.

Under the specific guidance and organization of teachers, they can criticize themselves and evaluate others realistically.

Third, mathematical thinking.

1. Experience the process of understanding decimals in real situations, learn to describe and express phenomena in the real world with numbers, and develop a sense of numbers.

2. Using the existing mathematical knowledge and life experience, explore the writing calculation and estimation methods of the process of dividing three digits by one digit, multiplying two digits by two digits, and adding and subtracting one decimal, and cultivate the ability of abstract generalization and reasoning.

3. In the process of using mathematical knowledge and life experience to solve practical problems, understand some common quantitative relations and develop abstract thinking.

4. In the process of exploring the formula for calculating the area of rectangle and square, mathematical activities such as observation and experiment are carried out. Develop the ability of rational reasoning and deductive reasoning.

5. Develop the concept of statistics in the process of studying the method of averaging a group of data and solving practical problems by using statistical methods.

6. Cultivate students' initial ability to clearly express their thinking process.

Fourth, solve the problem.

1, can apply the operational knowledge learned in this textbook, solve practical problems in life, and cultivate application consciousness. On the basis of understanding the meaning of area and the calculation method of rectangular and square area, some practical problems are actively solved.

2. Further learning to collect and sort out the data in real life according to the practical problems to be solved can solve some simple practical problems related to the average, realize the importance of data and enhance the statistical concept.

3. Increase the experience of cooperating with peers to solve problems, take the initiative to learn from classmates, and actively exchange ideas and methods for solving problems with classmates.

4. Under the guidance of teachers, they can often reflect on their learning activities and accumulate experience in mathematics activities. Estimation can be used to judge the rationality of the solution.

Action taken by verb (abbreviation of verb):

1. Create a free, open and safe learning atmosphere, expand students' thinking and stimulate innovation.

2. Introduce open examples in the classroom, so that students can promote the development of divergent and divergent thinking in exploration.

3. Reform the spatial organization form of classroom teaching, adopt the forms of problem-based teaching and group cooperation and exchange in the lesson plan channel of China Education Universal Network, reveal the laws of knowledge and methods to solve problems, learn to help each other in problems and cooperation and exchange, realize the complementarity of learning, enhance the sense of cooperation and improve the communication ability.

4. Create problem situations and encourage students to question boldly.

5. Encourage students who have spare capacity to study to actively participate in outward bound training, and prepare some exercises at different levels in class to stimulate their interest in learning mathematics and give full play to their potential.

Sixth, the goal of struggle

1. Under the guidance of teachers, collect and combine information from real life and real situations, find and put forward simple mathematical problems, thus developing the consciousness of mathematical application.

2. Under the guidance of teachers, make a preliminary study reflection and evaluation.

3. Under the encouragement and guidance of teachers, I can actively participate in observation, operation, exploration, communication and other mathematical activities, and I am curious about some things related to mathematics around me, interested in learning content and learning activities, and have the desire to learn mathematics well.

With the encouragement and help of teachers and classmates, we can overcome the difficulties in mathematics activities, gain successful experience initially, and further cultivate our desire to learn mathematics well.

5. In the process of solving practical problems, further study the lesson plan channel of China Education Universal Network to think in an orderly way, grasp the relationship between quantity and cultivate rational reasoning ability and deductive reasoning ability.
