I taught fair games in the open class competition organized by the Education Commission a few days ago.
.
This math teaching activity.
1
Create a learning situation that students can easily accept. In this class, I showed a lively and interesting student learning process. An object that can be attacked reasonably
This content is full of life breath, which fully embodies the new curriculum concept of "there is mathematics in life and mathematics comes from life". And games have always been children.
Children's favorite topic. It is a child's nature to be active and playful. So, I thought, why not conform to this nature and let this content really come from life?
Coming? So from the beginning, I created the atmosphere where we play games today, and at the same time created the game activities of giving gifts, and enjoyed it.
The main line to teach. In this way, students are full of interest and greatly stimulate their awareness of subject participation.
A good beginning is only half the battle. After creating a situation that attracts students, how to make students really "play" in middle school?
I use the situation of Xiaoming and Xiaohua playing chess provided in the textbook to decide who should go first, and ask questions in time to make students think about what to do.
To decide who goes first. The students were very active at this time and came up with many ways, such as drawing lots, tossing coins, cutting paper with stones and so on. , the problem was mobilized.
The enthusiasm of students, they use their existing life experience to solve problems. Then naturally smile method:
"greater than
three
Electric pin
Time takes precedence, less than
three
Do you think this method is good? Is it fair? The students had a heated discussion and expressed their opinions in succession.
In terms of time, I arranged some time for students to talk and make them realize that laughing is unfair. In this way of discussion,
Students can easily accept new knowledge, because they are interested in games, so they devote themselves to exploration activities.

The content of this course has the characteristics of activity, process and experience, so I pay attention to let students engage in experiments in person and guide them to collect and try.
Check the data, analyze the test results, and experience the possibility in the process of activities and the fairness of the rules of the game. The students mentioned in the previous question.
The way of throwing dice and coins is just like laughing and being naughty. Organize students to discuss whether the method is fair or not. Because students
Only by personally passing the experiment can he have a better experience, so I ask the students to roll dice and coins before class. Every student throws it.

And record the experimental results. In class, students can analyze their opinions through data, so as to avoid superficiality.
Discuss it. This activity realizes everyone's participation, saves time for classroom teaching and makes teaching more effective. Through discussion and the math I showed,
Scientists' scientific experiments show that coin toss is fair, so students can understand the so-called fairness of the game and the possibility of winning or losing.
Sample.
three
Arrange exercises at different levels so that students can apply what they have learned. When the students gained new knowledge, I did some corresponding exercises. first floor
Second, students can judge whether the rules of the game are fair or not. At the second level, students can modify unfair rules of the game through new knowledge. The third level, learning.
Students will design fair rules of the game. The fourth level, students analyze some phenomena in life. My goal is to pass a series of
Practice can not only enable students to consolidate new knowledge, but also better apply new knowledge to solve some practical problems.
The overall feeling,
Through teaching
,
I think organizing activities should go from shallow to deep.
Through the experiment of "question-debate-conclusion"
Verifying-analyzing data-modifying rules-designing new rules of the game "allows students to fully participate in the whole process of activities and gradually deepen their learning."
The experience and feeling of the possibility of equivalence between students and the fairness of the rules of the game. At the same time, let students experience in activities: true knowledge comes from practice, using facts.
Let's talk about it. Experiments play a role in verification and are a good learning method. Of course, mathematics teaching is the teaching of mathematics activities, for teachers and students.
The process of interaction and common development between students. In a series of activities, don't forget to communicate with the whole class in time.
Everyone fully expresses their ideas, and teachers should not make a single statement, so that students' enthusiasm for participation will be higher. The teacher is not anymore.
The leader of the classroom, but the guide, grasps the wonderful generation of students in time to make the classroom more exciting and effective.
