How to Make Rational Mathematics Classroom Full of Interest

Primary school students are in the initial stage of life, lively and active, and have some antipathy and resistance to the rigid classroom teaching mode. According to the characteristics of primary school students, primary school mathematics classroom should not only be a simple knowledge transfer, but also be interesting and participatory. Under the guidance of interest, students participate in the process of knowledge generation and development through various forms of autonomous learning activities, so that students can think freely, discuss equally and imagine boldly in a harmonious atmosphere. Only in this way can students get rid of boredom, stimulate interest, develop their personality and experience success.

Bruner, an American psychologist, said: "The best motivation for learning is to be interested in the textbook itself." Therefore, teachers should carefully choose interesting text contents, such as math stories, interesting math problems, math riddles, math historical materials and so on. As long as students find these questions difficult, interesting and unattainable, they can be free from the restrictions of textbooks and curriculum standards. For example, after teaching the lesson "Divisibility of Numbers", I chose an interesting topic: "Slaughterhouse wants to kill 100 pigs, butchers arrange pigs in a row, first kill the first one, then kill the other one. After killing the first time, don't disturb the pig team, kill the second time in the same way, and so on, until there is only one left, he will stop killing. Please think about it: How many pigs are safe? " After reading the questions, the students scrambled to speak, but they couldn't get to the point of solving the problems. Therefore, I suggest killing 10 pigs first to see which pig can survive. Students number 10 pigs, and kill odd numbers instead of even numbers according to the method of killing 100 pigs. It turns out that the eighth pig can avoid being killed. A stone stirs up a thousand waves. The floodgates of students' thinking are opened and their enthusiasm is high. In a happy and tense atmosphere, they finally found the correct answer: the pig in position 64 is safe.

Six or seven-year-old children's attention can only last 10 to 15 minutes, and older children can't last. In teaching, teachers should pay attention to creating a pleasant learning environment for students, adopt flexible and diverse teaching methods and forms that students like, stimulate students' subjective initiative and develop students' attention. For example, in the "Interesting Geometry" class, I first let the students listen to a soundtrack story "Geometry in Ancient China". Its content is an unearthed painting with two primitive people, Fuxi and Nu Wa. Fuxi holds a "moment" (triangular ruler), and Nu Wa holds a "gauge" (compass). Then, I showed a problem: count the number of squares. On this basis, I asked the students to guess a riddle: "Round head and sharp legs, flying on one foot when walking. Turn around and stand up again and draw a grand blueprint. " The students were eager to try, and after a heated debate, they guessed the answer.

Finally, play the game of "delivering packages". I chose a student as a drummer, covered his eyes with a towel, and asked the rest of the students to pass a small red flower in turn in the rapid drums. I put a small paper roll in the stamen of this little red flower in advance, and interesting geometric questions were written on the paper roll. As soon as the drums stop, whoever reaches the small red flower will open the small paper roll and read the questions on the paper roll, which will soon be solved. When playing games, the classroom is full of happy atmosphere. In the enthusiastic game activities, the students' learning enthusiasm was mobilized.

Interest is the secret of successful teaching. Teachers use a variety of teaching methods to enhance the interest in mathematics classroom teaching, which can arouse students' enthusiasm and make students change from passive to active, learn to learn and be willing to learn. In my opinion, it should be the teacher's goal to let students acquire knowledge in a relaxed and pleasant atmosphere, let their thinking soar, inspire their inspiration and make the classroom colorful.
