First-year primary school students have just come out of kindergarten. They are naive and love to talk and move, and have poor binding force on their own behavior, and their attention is easily distracted. In order to stimulate their interest in learning mathematics and feel the charm of mathematics, teachers should pay special attention to the introduction of new courses. Yu Yi, a famous special-grade teacher, once said, "The first hammer in class should knock on students' hearts, stimulate their thinking sparks, or attract students as firmly as a magnet. "A good introduction of new courses can quickly arouse students' cognitive conflicts, stimulate students' interest in learning, and let students naturally enter the best learning state. According to the usual teaching practice, I have compiled the following guiding methods:

First, the story introduction method

Children who have just entered school like listening to stories best. Now, the textbook of senior one mathematics has undergone great changes in form, just like a beautiful fairy tale book. The content of each question in each class can be expressed by a short story, which is closely related to students' real life.

For example, when teaching "how much to compare", I told a story: three little pigs learned the skills of building a house, the first little pig learned to build a straw house, and the wolf blew it down in one breath; The second little pig built a wooden house, and the wolf slammed the door open. The third little pig studied hard and built a brick house. The wolf did his best, but he didn't destroy it. The children said that brick houses were stronger, and then I went on to say that because pigs have experience in building houses, rabbits invited pigs to help. Let's have a look. What are they doing? Through this lively and interesting story, new knowledge and questions are put forward, which naturally stimulates students' interest in learning and allows students to start learning in a pleasant environment, which is in line with the age characteristics of students.

Second, the game introduction method

Chen Heqin, a famous educator, said: "Children are naturally active and born of games." First-year students have obvious characteristics of children, and play is still their important spiritual food. Therefore, the introduction of games can often arouse their interest and achieve good teaching results.

For example, when teaching the concept of "up, down, front, back, left and right", the teacher said, "Children, reach out your hand and do actions with the teacher (up, down, front, back, left and right). Let's compare and see who is the best, shall we? " The speed of the game is from slow to fast. After the game, let the children say which directions are mentioned in the game. Students will say up, down, front, back, left and right quickly.

This kind of lead-in is lively and interesting, which enables students to start teaching with their familiar "hands" in a relaxed atmosphere, highlights students' direct feelings, integrates knowledge and interest, and makes education entertaining.

Third, the introduction method of physical demonstration

Primary school students' thinking is mainly based on figurative thinking, while abstract logical thinking depends largely on perceptual experience. Therefore, using physical demonstration to transform abstract concepts into concrete objects can clear the way for new curriculum teaching. Physical demonstration allows students to explore knowledge, master knowledge and enjoy the happiness of success through their own hands and brains.

For example, when teaching "separation and combination", I asked students to put four discs on the table, and then divided the four discs into two parts, asking: how many, how many? Students look at the discs on the table and quickly get the answer: they can be divided into 1 and 3,3 and 1, 2 and 2. For example, when teaching ordinal numbers, students can queue up in groups and talk about where they are and who they are.

Introducing the physical demonstration method into the new class is vivid, intuitive and vivid, which leaves a deep impression on students, not only enriching their perceptual knowledge, but also multiplying their interest in learning.

Fourth, music introduction method

Music can arouse students' emotional singing, thus creating a harmonious teaching environment, creating a warm and elegant classroom atmosphere and stimulating students' interest in learning.

For example, I skillfully used this method when I was teaching "10 addition". "Find a friend, find a good friend, salute and shake hands, you are my good friend ..." With the song played, I took the math card 4, and then found the children with the math card 6, and they saluted and shook hands. Q: Why are we good friends? Students can quickly answer, "Because your math cards add up to 10." I said while the iron was hot, "Can you find your good friend?" The children consolidated the addition of 10 while singing "Finding Friends". With the charm of music, students are attracted to the mathematics knowledge to be taught soon.

Above, I have analyzed several methods of classroom teaching introduction, but the methods of teaching introduction are far more than these. In teaching, teachers should combine teaching practice and choose effective methods to realize the optimization of classroom teaching. In short, the introduction of mathematics classroom teaching is the key for teachers to open the door of teaching situation, which can play a leading role and attract attention. It is the comprehensive embodiment of teachers' knowledge, eloquence and wisdom, and should be explored continuously in teaching.
