《义务教育数学课程标准》明确指出:“数学教学是数学活动,教师要紧密联系学生的生活环境,从学生的经验和已有的知识出发,创设生动的数学情境……”“数学教学应努力激发学生的学习情感,将数学与学生的生活、学习联系起来,学习有活力的、活生生的数学。”可见,生活离不开数学,数学离不开生活。数学知识源于生活而最终服务于生活。尤其是小学数学,在生活中都能得到其原型。我们必须强化小学数学教学的生活性,从实际出发,捕捉生活中的数学现象,挖掘数学知识的生活内涵,把教材内容与“生活现
”Compulsory education mathematics curriculum standards“ clearly states: ”Mathematics teaching is a mathematical activity, teachers must closely contact students ’living environment, starting from the students’ experience and existing knowledge, to create a vivid mathematical situation ... “ ”Mathematics Teaching should strive to stimulate students ’sentiments of learning, linking mathematics with students’ life and learning, and learning dynamic and living math. "It can be seen that life can not be separated from mathematics, and mathematics can not be separated from life. Mathematical knowledge originates from life and ultimately serves life. Especially in elementary mathematics, in life can get its prototype. We must strengthen the life of mathematics teaching in primary schools, start from the reality, capture the mathematical phenomena in life, dig the life connotation of mathematics knowledge,
