数学家华罗庚曾说:“宇宙之大,粒子之微,火箭之速,化工之巧,地球之变,日用之繁,无处不用数学。”这是对数学与生活关系的精彩描述。生活离不开数学,数学源于生活,数学与生活永远无法剥离。尤其是《小学数学课程标准》的颁布实施,使我们更加深切地体会到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的知识出发,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,学会从数学的角度去观察事物、思考问题,激发学生对数学的兴趣,以及学好数学的愿望。
Mathematician Hua Luogeng once said: “This is a wonderful description of the relationship between mathematics and life,” “the universe, the micro-particles, the rocket’s speed, the cleverness of the earth, the change of the earth, the complex of daily necessities.” . Life can not be separated from mathematics, mathematics from life, mathematics and life can never be stripped. In particular, the promulgation and implementation of the Standard for Primary Mathematics Curriculum enables us to understand more deeply that mathematics teaching should be closely linked with the students ’actual life. Based on the students’ life experiences and existing knowledge, we should create vivid and interesting situations and guide students to carry out Observation, operation, conjecture, reasoning, communication and other activities to enable students to master basic mathematical knowledge and skills through mathematical activities, to learn to observe things from a mathematical point of view, to think about problems, to stimulate students’ interest in mathematics, and to learn math .
