Mathematics is highly generalized and abstract. Traditional teaching methods will make classroom teaching boring and students' learning efficiency is extremely low. How to make boring classroom teaching acceptable to students? According to educational psychology, an internal motivation that directly promotes students' learning is learning motivation, which is manifested in the forms of learning intention, desire and interest. Interest is a psychological tendency for a person to try to contact and know something, which can generate motivation for people's actions; Interest in learning is the power to promote students' knowledge. Therefore, in order to improve teaching efficiency, teachers should work harder to stimulate students' interest in learning. In teaching practice, I stimulate students' interest in learning from the following aspects:

First, cleverly set the situation and introduce interest

How to introduce new knowledge skillfully is an excellent opportunity to stimulate students' interest in learning and desire for knowledge. Primary school students are in a transitional period of unintentional and intentional attention, and some novel and interesting things can easily attract their unintentional attention. Therefore, carefully creating a good educational situation can make children concentrate and stimulate their interest in learning, which will bring twice the result with half the effort to classroom teaching. Mathematics originates from life, exists in life and is used in life. Therefore, in mathematics classroom, we should create a "life-oriented" teaching situation, organically combine the contents of teaching materials with students' real life, and design interesting and meaningful classroom situations, so that students can realize that mathematics is around and there is mathematics everywhere in their lives, so as to feel the fun of learning mathematics and fall in love with it.

For example, when teaching classification, I designed the classroom as a small shopping supermarket, allowing students to shop freely: treat themselves as "customers", and students go to various fields of the supermarket to choose what they need and see who is the fastest. The children's enthusiasm is very high, and their enthusiasm is mobilized at once, which deepens their understanding of classification in mathematics activities. This kind of teaching comes from the life situation, allowing students to observe with their eyes, operate with their hands and think with their brains. Let children's various senses participate in learning activities to stimulate thinking, which embodies the teaching concept of "learning by moving" and "playing with learning".

Second, use visual teaching AIDS, operational learning tools and audio-visual teaching methods to stimulate learning interest.

The junior students think better in images, but worse in abstractions. At this age, they tend to remember vivid, vivid and concrete things, but have no interest in boring, single, boring and abstract mathematics knowledge. Therefore, I attach great importance to intuitive teaching in mathematics teaching. Through various sensory activities such as listening, doing, speaking and thinking, students gradually accumulate rich perceptual knowledge and gradually become interested in new things, which is the main means for students to learn new knowledge and promote the development of thinking. For example, when I teach the understanding of numbers within 10, students can form a correct concept of numbers by putting sticks and drawing pictures. When I was teaching the decomposition of 5, I drew it vividly and asked the students to take out five sticks. First of all, I take 1 in my left hand and 4 in my right hand, which makes ***5. Ask the students to look at their hands and say, "5 can be divided by 1 and 4." Then let the students take two in their left hand and three in their right hand. Let the students look at their hands and say, "Five can be divided into two and three. Periodical articles are classified and inquired in periodical library. Using five sticks, students can talk while holding sticks. Students quickly master the composition decomposition of 5 and the addition and subtraction of 5. In addition, the basic knowledge of geometry in senior one needs intuitive teaching, so that students can see and touch it, so as to cultivate their observation ability and get a preliminary understanding of geometric shapes. For example, when teaching cuboids, cubes, cylinders and spheres, I ask students to find matchboxes, flashlights, medicine boxes and cans from home, classify these things according to the characteristics of cuboids, cubes, cylinders and spheres, guide students to understand the characteristics of these shapes after classification, and then ask students to cite examples in daily life. Because of the intuitive teaching, combined with common things in life, it aroused students' interest. On the physical education class, they pointed to the ball and said sphere, and pointed to the mat and said cuboid. In this way, students quickly mastered the teaching content of this course.

Thirdly, diversified teaching methods stimulate students' thirst for knowledge.

Diversified teaching methods can make children concentrate and stimulate their interest in learning, which will bring twice the result with half the effort to classroom teaching. So when teaching students to recognize and count, I use concrete images and some interesting stories to stimulate students' interest. For example, in order to make students remember the shape of the number 1-9, I taught them to recite the jingle: "1 is like chalk, 2 is like a duck, 3 is like an ear, 4 is like a flag, 5 is like a hook, 6 is like a whistle, 7 is like a silver hoe, 8 is like a gourd and 9 is like a tadpole." Help students memorize glyphs. Through this kind of teaching, the content of mathematics is endowed with certain emotional color, and the knowledge of mathematics is infiltrated into fairy tales, thus stimulating students' interest in learning mathematics. In addition, you can also make your own games and nursery rhymes according to the teaching content or the actual situation of students, so as to create a pleasant learning atmosphere for students and let them experience the fun of learning, thus generating a strong interest in learning.

Fourth, clarify the purpose of learning mathematics and stimulate students' interest in learning mathematics.

Students' clear learning purpose and correct learning attitude are long-term factors that play a role in improving learning enthusiasm. Teachers should take every opportunity to educate students on the importance and necessity of learning mathematics, so that students can clearly understand the social significance of learning mathematics, see the practical value of mathematics and induce their learning motivation.

In the teaching process, teachers should present mathematics in a life-like way, so that students can feel that mathematics comes from life and mathematics is everywhere. To clearly put forward and explain the significance and importance of subject content, we can also solve practical problems in life through what we have learned, so that they can feel that there is mathematics everywhere in their lives, realize the importance of mathematics learning, and stimulate and cultivate correct learning motivation. For example, after learning the "length unit", students can first estimate the height of desks and chairs, and then actually measure them with decimeters to see who estimates them most accurately. You can also use the method of step measurement to measure the length of a circle of the school playground and so on. This fully mobilized the students' enthusiasm and made all students actively participate in learning activities. Students experienced the practical application of mathematics knowledge in life through their own personal practice, thus improving their enthusiasm for learning. In the long-term mathematics study, students gradually clarify the meaning of learning and have fun in exploring mathematics knowledge, so as to maintain a positive attitude in the future mathematics study and actively participate in teaching activities, thus obtaining the best learning effect.

In short, the cultivation and stimulation of students' interest in learning mathematics depends on the careful cultivation and care of mathematics teachers. As long as we can carefully create some fascinating teaching scenes and dig out some interesting factors in each math class, the math class will be full of climax and fun, which will fundamentally improve the negative characteristics of mathematics, make students feel happy in the process of learning mathematics, and make students realize that they are the discoverers of learning activities.
