In the fun and challenge, students can learn to think about problems in an orderly and comprehensive manner, enjoy the fun of mathematical reasoning, and improve their mathematical thinking ability.
Teacher Deng Weiwei led the children of Class 4.1 to explore the characteristics of triangles, starting from the students' self-learning questions, what is the height of a triangle, how to draw the height of a triangle, etc., and led the children to explore the characteristics of triangles. In the classroom, students give full play to the main position of students through a variety of activities such as looking, talking, drawing, and thinking, and hand over the class to students.
In this lesson, Ms. Lv Yan, the third-grade teacher, made full use of the students' existing life experience and intuitively understood the meaning of the area: by touching the action of touching the book desktop, looking for what other activities around her had area, and initially perceived the meaning of the area; Ms. Lv designed various gradient exercises according to the psychological characteristics of the students in the middle section, which stimulated the students' strong interest in learning. When comparing the area of a rectangle and a square, ask the students if they can compare them at once, so that the students can further realize the necessity of a unified unit of measurement in the process of arranging the shop.
Teacher Lai Ying brought a lesson of "The Sum of the Inner Angles of Triangles" in Class 4.3, and tried to let students gain direct experience through experimental operations such as geometric drawing boards, origami and paper-cutting, starting from students' direct experience, gradually turning to symbolic processing, and finally achieving reasoning and argumentation, and learning to express mathematical laws in mathematical language. Let students rise from perceptual thinking to rational thinking. In this process, the idea of "transformation" was used to transform the three inner angles of the triangle into flat angles, and the sum of the inner angles of the triangle was explored and proved to be equal to 180° from multiple angles, which broke through the difficulties of this lesson, infiltrated the idea of mathematical transformation, and focused on cultivating students' mathematical literacy.
Teacher Huang Qianqian brought - "cuboid, cuboid surface area exercises", the teacher's basic teaching skills are solid, in the classroom, step by step, from the surface area formula - surface area calculation - piecing together the calculation of surface area, guide students to think actively, let students find rules in practice and calculation, summarize methods. When teaching new knowledge, students can experience the connection between knowledge and life, and can guide students to engage in independent learning and cooperative inquiry throughout the teaching process. Immediate evaluations of students are developmental and motivating. Moral and intellectual education is also infiltrated into the curriculum to cultivate students' all-round development and cultivate students' core values.
Teacher Yang Yi brought the "Movement of Graphics - Rotation", which is introduced by daily life experience, attaches importance to the creation of scenarios, and strives to play an active role in mathematical inquiry, mathematical discovery, teaching abstraction, mathematical modeling, and teaching understanding. It also attaches great importance to the participation of students, and strives to reflect the main position of students in teaching and learning. The design ideas are clear, the board book design is organized, and the layout is reasonable. Students work in small groups to design solutions and experience the joy of self-directed learning in the midst of conflicting ideas, so that they can learn to think mathematically.
Teacher Hu Qiao's "Surface Area of Cuboids and Cubes" focuses on starting from students' existing knowledge, actively constructing, exploring new knowledge while reviewing old knowledge, and teaching pulse is clear, interlocking, and progressive, so that students can fully study, research, and discuss independently, so as to draw conclusions, cultivate students' thinking ability and practical operation ability, give full play to the main position of students, stimulate students' interest in learning, and ignite the flower of students' thinking.

After a series of wonderful class activities, we not only saw the professionalism and teaching talent of the teachers, but also felt their love and dedication to education. These classes are not only the transmission of knowledge, but also the touch of the soul, the collision of wisdom, the burning of passion, and the condensation and application of achievements. As the saying goes, "an individual goes fast, a group of people goes far", so behind the competition is what we should pay more attention to. The real significance of this competition for young teachers lies in the organic combination of competition courses and subject discussions, and the promotion of professional growth of subject teachers in the simplest way. The competition class is never the growth of one person, but the growth of a group of people. Let us move forward hand in hand, continue to explore and make progress on the road of education, and jointly write a beautiful chapter of education.
