新课标指出:“数学教学必须从学生熟悉的生活情境和感兴趣的事物出发,为他们提供观察与操作的机会,使学生体会到数学就在身边,感受到数学的趣味和作用,对数学产生亲切感。”因此,教师在教学中,应培养学生用数学的眼光从生活中捕捉数学问题的能力,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。同时还要充分挖掘数学知识本身所蕴含的生活性、趣味性,促使学生学会质疑和进行自主研究,主动寻觅数学与生活之间的密切关
The new curriculum standard states: “Mathematics teaching must start from students' familiar life situations and interesting things, provide them opportunities of observation and operation, enable students to realize that mathematics is at their side and feel the interest and function of mathematics. Mathematics produces a sense of intimacy. ”Therefore, in teaching, teachers should cultivate their ability to capture mathematical problems from the perspective of mathematics, take the initiative to use mathematical knowledge to analyze the phenomena of life, and independently solve practical problems in life. At the same time, we should also make full use of the life and interest contained in the knowledge of mathematics, urge the students to learn to question and conduct independent research, and actively look for the close relationship between mathematics and life
