著名数学家华罗庚先生曾经说过:“宇宙之大、粒子之微、火箭之速、化工之巧、地球之变、生物之谜、日用之繁,无处不用数学。”此言是对数学工具性和应用性的最精辟的描述,同时揭示了数学与生活千丝万缕的联系,也对我们数学教学提出了明确的要求,即“依托生活,返回生活,实践第一”。的确,生活是一切教育的源头活水,更是数学知识产生的天然场所,只有将教育与生活密切联系起来,才能让教育回归生活世界,实现教育最根本的目标。一、创设生活化情境,使数学知识充满生活气息
The famous mathematician Mr. Hua Luogeng once said: “The universe is large, the tiny particles, the rocket speed, the cleverness of the earth, the change of the earth, the mystery of biology, the complex of everyday use, and mathematics everywhere.” The most incisive description of the instrumental and applicative properties of mathematics reveals both the inextricable link between mathematics and life and the explicit requirement of our mathematics teaching that “relying on life, returning to life and practicing first” ". Indeed, living is the source of all education. It is also a natural place for the production of mathematical knowledge. Only by closely linking education with life, can education be brought back to the real world and the most fundamental goal of education. First, create a life situation, full of life knowledge of mathematics
