The formation of pupils' thirst for knowledge goes through three stages: curiosity-knowledge-exploration. Curiosity is a child's nature, and many important inventions and discoveries of new technologies in the world often begin with curiosity. Newton's discovery of gravity is inseparable from his curiosity about the free fall of apples. Chen Jingrun's Goldbach conjecture is inseparable from his curiosity that 1+2 equals 3. Curiosity makes people full of the spirit of tracing the source. Willing to explore the mysteries of things and discover their strangeness. Therefore, students should be guided to ask curious questions in class. For example, when teaching the cone volume formula, students often pay little attention to the condition of equal bottom height after reading the book. At this time, I cleverly set a trap to set suspense. Students carry out the experiment of pouring water: fill a conical container with water and pour it into a cylindrical container. After a while, one group poured water, but it was not filled; Another group of students shouted: the water overflowed! What is the reason? The students are talking about it.

Second, active exploration leads to innovation.

Friedenthal, a Dutch writer, believes that the knowledge and ability gained through his own activities are more thoroughly understood and mastered than others. At the same time, he is good at application. Generally speaking, he has a strong memory. He also thinks that discovery is a pleasure. Re-creation is the main way and method to cultivate students' innovative thinking in primary mathematics. For example, when teaching the volume formula of a cylinder, let the students take out the cylinder and operate it according to the steps of cutting, spelling and turning, and then get the general volume formula. I asked this question: Can you put the spliced cuboid at a different angle? What do you find? At this time, the students raised their hands and said their findings. The volume of the original cylinder can be obtained by multiplying the radius of the bottom surface by half the area of the side surface. Students' innovative thinking has been well developed in the process of updating and perfecting the cognitive structure.

Third, communication stimulates innovation.

Innovative thinking is simply creative thinking, such as recreating existing knowledge and experience in different directions and to different degrees. So as to obtain new, unique and valuable new experiences, new knowledge, new methods and other creative achievements. In teaching, while cultivating students' positive thinking, students are encouraged to look at and understand things from a negative perspective and think. This is often unique, and uniqueness often leads to novel and unique discoveries and breakthroughs. Analyzing the quantitative relationship of application problems can guide students to understand reverse thinking while mastering positive thinking. If there are four more red flowers than yellow flowers, without changing the meaning of the question, let the students say that there are four fewer yellow flowers than red flowers, and four fewer red flowers are as many as yellow flowers.

Another example is that the number of students in class 6/kloc-0 is1112 of the number of students in class 62. Ask the students to say that class 62 is 12/ 1 1, and the ratio of class 6 1 to class 62 is1:65433. In the usual teaching, teachers should not only train students' concentrated thinking, but also create more opportunities for students to train and develop their thinking, and set up some open exercises to make students not only good at one-way thinking, but also get used to multi-directional thinking and develop different thinking. For example, in the content of year, month and day, the teacher did not follow the textbook order, but on the basis of introducing the relevant scientific knowledge of year and day, let the students calculate how many days there are in a year by themselves. The students used their original knowledge to come up with different calculation methods. ( 1) 3 1 * 7+30 * 4+28 3 1 * 7+30 * 4+29 (2) 90+9 1+92 * 2 9 1 * 2+92 * 2 (.

Fourth, encourage the successful cultivation of innovation

Psychological research shows that happy and excited mood and mild and relaxed learning environment have the function of expanding and strengthening knowledge innovation thinking activities. In teaching, we should strive to create an atmosphere, encourage success, let students experience the joy of success and show their talents. Therefore, teachers must let students express their opinions, choose their own learning methods and communicate freely. Suhomlinski said that the joy of success is a huge emotional force and a driving force for continuing learning. In classroom teaching, we should set up corresponding exercises for all students and students at different levels, so that every student can enjoy the joy of success in participating in activities and enhance their sense of innovation. The key to cultivate students' innovative consciousness lies in teachers' painstaking enlightenment and cultivation of students, fully tapping the sparks of teaching materials and students' divergent thinking, and infiltrating creative thinking into all aspects of teaching by using the organic combination of various thinking trainings. Students' innovative thinking and spirit must be fully developed.
