Program of Mathematical Practice Activities 1 I. Purpose of Activities:
Through mathematical practice activities, students can understand the close relationship between mathematics and nature, mathematics and human society, enhance their understanding of mathematics, enhance their confidence in applying mathematics, enable them to learn to observe, analyze and understand society by using mathematical thinking mode, and initially apply their learned mathematical knowledge to solve problems in daily life, thus cultivating students' spirit of exploration and innovation and making plans for mathematical practice activities.
Second, the principle of activities:
1. Discipline principle: Mathematical practice activities must closely focus on the application of mathematical knowledge and the content of mathematical textbooks;
2. Practical principle: Mathematical practice activities must be based on students' practical activities, and must be students' practical activities such as investigation, interview, interview, production and public welfare labor;
3. The principle of full participation: Mathematics practice should be an activity in which all students participate, and it is by no means an activity in which teachers or individual students demonstrate or some students operate, while other students watch the excitement and just talk without doing it;
4. Applicability principle of knowledge: In mathematics practice, students should apply what they have learned, and teachers should dig out the factors closely related to real life in textbooks, so that students can observe society and solve practical problems in daily life by using mathematical thinking mode;
5. Exploration and innovation principle: Mathematics practice is that students practice independently with the help of teachers. Teachers don't have to limit the ideas, ways and methods to solve problems, so that students can fully use their brains, make bold attempts and try to complete tasks with new inventions;
6. Principle of activity diversity: the diversity of mathematical practice activities includes the diversity of activity venues: indoor, outdoor, in-class, extracurricular, on-campus or off-campus; There are various activities: such as visiting, visiting, thinking, making, observing, experimenting, investigating, discussing, reading, operating, competing and performing. There are various forms of organization: individual activities, group activities, class activities, etc.
Three. Activity content:
The teaching contents of the twelfth volume of primary school mathematics textbook include: percentage; Cylinders, cones and spheres; Simple statistics, sorting and review, etc. According to the teaching content of the textbook, the content of mathematics practice activities in the next semester of grade six is determined as follows:
1, according to the percentage of the teaching content of the textbook, carry out mathematical practice activities with the theme of "small banks". Through practical activities, students can understand the meaning of saving and relevant knowledge about saving. The activity time is in March, and the planning scheme is "Mathematical Practice Activity Plan".

3. According to the knowledge of simple statistics, carry out mathematical practice activities with the theme of "simple statistics", let students conduct social surveys, and use the statistical knowledge they have learned to make simple statistics on the survey data. The activity time is in May.
Fourth, the activity organization:
1. Divide the class into several groups according to the students' living range, and choose the students with strong ability as the group leader. Team members should consider the performance of students in all aspects and put forward requirements for each group's activities.
The head teacher should get in touch with the community and units and get strong support from all walks of life; Or seek help from parents to facilitate students' activities.
2. The time of group activities is mainly in students' spare time, such as Saturday, Sunday and holidays. The activity mode is mainly group activities, or under the coordination of the group leader, the activities are reasonably divided and dispersed.
3. Set the ten-minute evening meeting every Friday as the exchange and summary time of practical activities of each group. The head teacher should understand the activities of each group and make reasonable adjustments to the form and content of the activities in order to effectively control the students' practical activities; At the same time, each group leader should summarize the activities of the past week and put forward specific requirements for next week's activities.

Activity flow:
First, create a situation and ask questions.
1. Teacher's statement: Xiao Qiang's grandmother's family recently built a new house. The floor occupied by the new house is rectangular, with a length of 15m and a width of 5m.
These days, Xiao Qiang's grandmother is thinking about building a fence. She wants to enclose a rectangle 20 meters long and 10 meters wide. Even the iron gates on the fence have been bought. The iron gate is 2 meters wide. However, she hasn't figured out how to build a fence yet. Students, today, let's all be "little designers" to help Xiao Qiang's grandmother with her ideas, shall we?
2. Let the students speak fully. Then the teacher summarized: affirmed the rationalization suggestions put forward by the students, and pointed out that today's class focused on the location of the fence.
Second, collaborative discussion and exploration methods
1. Group activities.
Distribute models of houses, fences (detachable) and doors to each group so that students can cooperate with each other and design the location of fences.
2. Panel report.
Each group sends a representative to the stage to demonstrate and explain their own design scheme. According to the student's demonstration, display the physical diagram on the computer and abstract the plane diagram.
It is estimated that there may be the following schemes (the shaded part indicates the house and the thick line indicates the iron gate):
3. In-depth study.
Guess.
Ask the students to guess which scheme Xiao Qiang's grandmother will choose, and give a preliminary explanation. (Encourage students to think from various angles)
2 calculation.
A. Question: How do we estimate how many bricks are needed to build the fence?
If it takes 200 bricks to build a fence with a length of 1 meter (the physical map is shown), can you calculate how many bricks are needed to build a fence designed by yourself? What about the enclosed open area? (The following table is displayed: length of fence. The number of bricks needed and the data of closed open space area are temporarily empty and need to be filled in)
B. students are divided into groups.
C. reporting. According to the student's report, the teacher gradually shows the completion of the following table:
3 think about it.
Question: Look at the calculated data. What are you going to say?
Focus on thinking:
A. what is the most economical material? Why? (After answering, the corresponding part in the table flashes)
B. what kind of map shows the largest open space area? Why? (After answering, the corresponding part in the table flashes)
After the students fully expressed their opinions, the teacher made a brief summary.
Third, apply what you have learned and solve problems.
1. Show me the problem.
2. Independent design.
3. Report on the discussion.
(1) Name the student to be reported, and the teacher will show the floor plan according to the student's report:
② Discussion: Which is the most material-saving? Why?
Obtained the second economic material. (Blink both sides of the fence in the second schematic diagram, and delete Figure ①)
4. Budget materials.
(1) Give the condition: If thin bamboo poles are used as fences and inserted every 5 cm, how many thin bamboo poles are needed to enclose this vegetable field?
(2) Students' calculations (free to discuss if there are difficulties).
(3) Student Report: (The computer is displayed next to the schematic diagram)
The area of a square is 4 square meters, which means that the side length is 2 meters.
Fence length: 2x2=4 (m) = 400 cm.
Number of bamboo poles: ①400÷5=80.
②400÷5-l=79 (root)
(4) Discussion: Should we "subtract 1"? Why "subtract 1"?
The computer simulates the process of inserting bamboo poles: flash a 5 cm long edge, insert a bamboo pole (accompanied by the sound of "Ding Dong"), (after inserting four bamboo poles in this way, the middle process is omitted until the last two are 5 cm) flash the penultimate 5 cm, insert a bamboo pole, and then flash the last 5 cm. Q: Do you need to insert another bamboo pole? Why? The flashing fence shows that the last bamboo pole can be omitted, so it should be "negative 1". (Delete the first item)
Fourth, summary method, activity summary
1. Summary method.
2. Choose "excellent designers" and let them tell their research results to Xiao Qiang's grandmother after class.
Activity hypothesis
At present, it is common among students that although the "two basics" are solid, their practical application ability is poor. This scheme selects the common example of "building a fence and enclosing a fence" in life. Starting from cultivating students' mathematical consciousness, while improving students' practical ability, we strive to do the following:
1. Focus on students as the main body and face all students.
From "creating situations and asking questions"-"collaborative discussion and exploring methods"-"applying what we have learned and solving problems"-"summarizing methods and carrying out activities", we always put students in the position of "subject of activities" and create a classroom environment in which students actively participate and learn. It provides a stage for each student to display their talents through group activities, class discussions and independent design, which fully embodies the integrity and autonomy of student activities.
2. Pay attention to cultivating students' innovative consciousness.
Guide students to try and guess boldly from different sides and angles, and put forward reasonable and unique methods to solve problems, which embodies the openness of activities and cultivates students' innovative consciousness. For example, the design of the fence, from the design scheme to the selection scheme, pays attention to let students fully express their opinions, thus reflecting the openness of classroom teaching.
3. Pay attention to the cultivation of students' sense of cooperation.
When designing the fence, group activities and group discussions are adopted, and when preparing the fence material budget, students are allowed to solve problems through free discussion, so as to cultivate students' consciousness and ability of unity and cooperation and enhance their practical ability.
4. Pay attention to cultivating students' practical ability.
It is an important way to learn and consolidate all kinds of knowledge. In teaching, we should try our best to dig out the contents related to real life in textbooks, so that students can practice, measure, test and use them, so that they can observe and analyze the real society with mathematical thinking in middle school. It is necessary to solve problems in daily life and then cultivate children's application skills.
Three activities and tasks are planned for mathematical practice activities:
1. Measure the circumference of the frustum.
2. Find out the items that have been placed according to the location.
3. Design the platform with the acquired items.
Activity objectives:
1. Students can use the given tools and try to measure the circumference of the central truncated cone in different ways.
2. Students can use their knowledge to judge the direction on the spot and find out the preset items according to the given orientation description.
3. After searching for articles, students can design square seats and tables according to their own aesthetic standards and the settings of the articles, which is beautiful and generous.
4. In the activities, students can actively discuss, cooperate in groups and exercise their cooperation ability.
Activity Form: This activity consists of four groups: Dividend, Yellow, Blue and Green, which are carried out in the form of group cooperation, group evaluation and joint coordination.
Activity arrangement:
1. Actual measurement: According to the tools provided (rope, tape measure, protractor), the division of labor within the group is reasonable, and different measurement methods can be adopted to compare who can finish the task within the specified time.
2. Searching for treasures in the square: according to the preset orientation, bury the "treasures" (decorations needed for designing the podium) in different orientations with different colors. Each group will describe the position in their hands and find the treasures corresponding to their own colors. We can't take the treasures of other groups and see which group takes the least time to win.
3. Little designer: According to the found treasures, discuss in the group and jointly design the layout of the podium in the square. The layout should be reasonable, beautiful and generous, and the time should be less. Designers who can clearly express their own group will win.
Activity evaluation: As a group, every time you win an activity, you will get a star. After all the activities were completed, which group won the most stars and which group finally won, and was awarded the title of "small expert in practice".
Activity focus: Complete the actual operation according to the tools provided.
Prepare moving tools: stopwatch, tape measure, rope, protractor, and students should bring their own small protractor.
Activity flow:
Students, today we gather in Yingtaogou Square for practical activities. This is a rare opportunity. In this activity, we will complete the task of breaking through the three customs. I hope that the students will actively use their brains and hands to complete the task together.

Mathematical Practice Activity Scheme 6 Chen Shibin Since the introduction of mathematical activity class as a new class in teaching, the advantages of the activity class have gradually emerged. Practice has proved that activity classes can cultivate students' flexible use, cultivate their interest in mathematics, broaden their thinking, induce their intelligence, and give full play to their personality, psychology, specialty and ability. However, there are still many problems in the development of activity classes. In order to implement activity classes, truly show the charm of activity classes, enable students to study, play and cooperate in middle schools, broaden their horizons, experience the value of mathematics, enhance their feelings for mathematics, form a sense of solving problems in mathematics, and further cultivate their interests, hobbies and innovative talents. The plan for this math activity class is as follows:
First, the student situation analysis:
Through understanding, the second-year students have acquired some preliminary observation ability, understanding ability and analysis ability after studying in the first grade for a whole school year. However, because students are young, active and inattentive, it is very necessary to carry out activity classes. The famous educator Suhomlinski once said: "The wisdom of children is at the fingertips." I think it is more suitable for junior primary school students. Therefore, in this activity class teaching, we should pay special attention to cultivating students' various abilities imperceptibly, gain more experience in exploring knowledge, and lay a good foundation for future study.
Second, the activity content:
In the process of implementing and developing education, various activities should complement other subjects. This activity class will take questioning and thinking after class as part of the activity class according to the age characteristics of students and the content of teaching materials, and arrange appropriate practical activities related to the teaching content, so that students can comprehensively improve their abilities of observation, operation, experiment, guessing, reasoning and communication through independent inquiry and group cooperation.
Three. Activity objectives:
1. Through the organization and development of activity classes, students are equipped with preliminary calculation skills, logical thinking ability and spatial concepts, as well as the ability to solve some simple practical problems by using the learned mathematical knowledge.
2. Cultivate students' interests and hobbies in learning mathematics.
3. Expand the vision of mathematics and broaden the field of knowledge.
4. Cultivate good thinking quality and reasonable thinking habits.
5. Develop personal advantages and stimulate potential functions.
6. Cultivate sentiment and develop good thinking habits and study habits.
Fourth, arrange the activities of observing objects to deepen the understanding and mastery of "symmetry". I will design patterns to appreciate and design patterns to guess and learn simple reasoning knowledge. Fifth, the methods and measures of activity classes:
1. Math game class: Through roaming the kingdom of mathematics, guessing digital puzzles, playing math poker, opening a math clinic, swimming in the maze of wisdom, "passing passwords", "finding friends", "delivering letters by postman" and "finding homes for small animals", teachers and students can jointly collect interesting questions and play games, which can not only cultivate students' interest, thinking ability and language expression ability, but also cultivate them.
2. Thinking training class: Students not only exercise the flexibility and profundity of students' thinking, but also induce their innovative thinking through independent activities, such as quick calculation and skillful calculation, multiple solutions to one problem, changeable problems, discovering laws, geometric figure transformation and recognition, testing your judgment, and open-ended topic training, so that their enthusiasm and creativity in learning can be maintained and developed.
3. Competition activity class: According to the characteristics of students' competitiveness, hold competitions such as "See who learns correctly and quickly", "See who puts it correctly and skillfully", "Win the red flag competition", "Men's and Women's competition", "Team competition" and "Little Expert". Cultivate students to participate in competition from an early age, not afraid of competition, and learn the ability to compete.
4. Practical application class: arrange practical activities to let students experience the close connection between mathematics and daily life. Such as social investigation, special interview, actual measurement, throwing, skipping, running, playing football, publishing newspapers and so on. These special practical activities make students gradually learn to observe and understand the things around them from the perspective of mathematics, thus cultivating and developing their mathematical ability, their awareness of mathematical application and their awareness of cooperation and communication with others.
5. Hands-on operation class: Use activity class to guide students to make intuitive learning tools, so that they can swing, fold, divide, weigh, measure, touch, count, daub and spell, so that students can use their hands and brains, which can not only consolidate and apply knowledge, but also improve students' hands-on operation ability, stimulate their interest, make them actively participate in learning and develop their abilities.
