Module 1: 1. The new curriculum standard points out that students' effective teaching activities cannot rely solely on imitation and memory, and hands-on practice, independent inquiry and cooperative communication are important ways for students to learn mathematics. Based on this understanding, we should pay attention to the reality of life from a scientific perspective in the teaching of cognitive scoring course. Different methods of solving problems have their own advantages and disadvantages. We should pay attention to students' existing knowledge and experience, understand the laws, and flexibly inspire and mobilize students' learning desires in various ways to meet their learning needs. And provide rich operating materials, so that students can participate in learning with their hands, mouth and brain, establish an intuitive mathematical model, gain a successful experience and enhance their self-confidence in learning. Throughout the class, teaching has the following characteristics: First, good teacher-student relationship promotes students' effective learning.

In the classroom, students are the "protagonists" and teachers are just a "supporting role". Only by fully reserving time and space for students and paying attention to students' emotions, attitudes and thinking in the learning process can teachers and students realize * * * in the classroom and promote students' effective learning. In the whole class, teachers always maintain a peaceful attitude and respect, treat and trust every student equally. From subtle movements, kind eyes and kind and polite teacher language, the tense psychological distance between teachers and students can be shortened, and students can be enthusiastic about cooperation with teachers. Please say something. You are absolutely right! You guys really think! These words and so on Let the listener feel that it is from the heart, reflecting family and humanistic care. It not only satisfies students spiritually, but also creates an atmosphere of exploration for the classroom.

Second, close the connection between mathematics and life, and cultivate students' consciousness of applying mathematics.

The curriculum standard points out that mathematics classroom teaching should emphasize understanding, learning and applying mathematics in the process of studying real life problems from students' knowledge, experience and life background. According to the cognitive characteristics of primary school students, this lesson starts with the familiar situation of "food for outing", and then expands its application, showing the familiar pictures around students, finding and talking about the things they like in life, which not only makes students feel that mathematics comes from life and is rooted in life, but also gradually cultivates their awareness of using mathematics.

Third, provide students with the opportunity to "do math"

In traditional teaching, the process of knowledge formation is taught by teachers. Teachers' teaching replaces students' operation and thinking, and students can't experience the formation process of knowledge. In this class, teachers fully provide students with opportunities to do mathematics, so that students can actively construct knowledge. Students form a shallow understanding of the meaning of fractions through courseware demonstration, and then communicate and express on the basis of concrete overlapping paintings, showing different graphic judgments and understandings. Through intuitive operation, demonstration, observation and association, the meaning of students' expressing scores is more and more clear and profound. From the initial appearance, a cake is divided into two parts on average, which can be expressed by half of the score, and gradually develops into the establishment of dividing an object into several parts on average, each part is its score, which can be expressed by half of the score. These mathematical knowledge is not directly instilled by the teacher, but experienced by the children themselves, forming certain skills, gaining positive experience and developing mathematical thinking ability.

In short, in the whole teaching process, teachers dare to let go, giving students time and space, so that they can gain mathematical knowledge through operation, observation, thinking and communication, get the bloom of thinking and glow with vitality.

In this way, students not only know the score, but also better understand its meaning.

Module 1 2. Applying reasonable mathematical conjecture can stimulate students' interest in learning, guide them to actively participate in the process of mathematics learning, urge them to have the desire to explore knowledge, improve their ability to observe and analyze problems, and enhance their creativity.

1. From a scientific point of view, different methods of solving problems have their own advantages and limitations. 2. The diversification of this problem-solving strategy is the new requirement of the new curriculum for teaching.

(4)。 Let the students know more about the meaning of a quarter.
