数学来源于生活,又应用于生活。数学家华罗庚曾经说过: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。这是对数学与生活的精彩描述。新的课程标准更多地强调学生用数学的眼光从生活中捕捉数学问题,主动地运用数学知识分析生活现象,自主地解决生活中的实际问题。因此,在数学教学中应重视学生的生活体验,把数学教学与学 Mathematics comes from life, but also used to life. Mathematician Hua Luogeng once said: the universe, the micro-particles, the rocket speed, the cleverness of the earth, the Earth’s change, the complex of daily use, ubiquitous mathematics. This is a wonderful description of mathematics and life. The new curriculum standard emphasizes that students should capture mathematical problems from the perspective of mathematics, take the initiative to use mathematical knowledge to analyze the phenomena of life, and independently solve the practical problems in life. Therefore, in mathematics teaching should pay attention to the student’s life experience, the mathematics teaching and learning
