《小学数学课程标准》指出:“数学教学,要紧密联系学生的生活实际,从学生的生活经验和已有知识出发,创设生动有趣的情境,引导学生开展观察、操作、猜想、推理、交流等活动,使学生通过数学活动,掌握基本的数学知识和技能,初步学会从数学的角度去观察事物、思考问题,激发对数学的兴趣,以及学好数学的愿望。”因此,在数学教学中,教师巧妙联系学生身边熟知的现象和经验,将数学与身边的事物联系起来,将数学学习从书本转到生活中去,从现实生活中发现问题、提出问题,解决问题,这样既能提高自己的学习兴趣,又会让学生感 The standard of primary school math curriculum states: “Mathematics teaching should be closely linked with the students ’actual life. Based on the students’ life experiences and existing knowledge, they should create vivid and interesting situations and guide students to observe, manipulate, guess, reason and communicate And other activities so that students through mathematics activities, master the basic mathematical knowledge and skills, the initial learn to look at things from the mathematical point of view, thinking about problems, to stimulate interest in mathematics, as well as the desire to learn mathematics. ”Therefore, in mathematics teaching , The teacher ingeniously contacts well-known phenomena and experiences around the students, connects the mathematics with the things around him, transfers the mathematics study from the books to the life, finds the problems in the real life, asks questions and solves the problems, so that he can improve himself Interest in learning, but also make students feel
