新课程标准指出:“数学教学活动必须建立在学生的认知发展水平和已有的知识经验基础之上。”平时的教学经验告诉我们,学生学会了数学知识,却不会解决与之有关的实际问题,造成了知识学习和知识应用的脱节,感受不到学习数学的乐趣。这对学生实践能力、创新能力和解决问题能力的培养是不利的。因此,作为教师要善于结合课堂教学内容,捕捉生活中的数学现象,挖掘数学知识的生活内涵。一、结合生活实例,创设情境,激发学生的学习兴趣 The new curriculum standard states: “Mathematics teaching activities must be based on the level of cognitive development of students and the existing knowledge and experience.” "The usual teaching experience tells us that students have learned math and can not solve problems associated with them Relevant practical problems have caused the disconnection between knowledge learning and knowledge application and can not feel the joy of learning mathematics. This is detrimental to students’ ability to practice, innovate and solve problems. Therefore, as teachers, they should be good at combining classroom teaching, capturing the mathematical phenomena in life, and exploring the life connotation of mathematical knowledge. First, with examples of life, create situations to stimulate student interest in learning
