《义务教育数学课程标准》明确强调,要高度重视于学生的生活实践中学习数学,理解数学。所以,教学小学数学知识应着重从学生身边熟悉的生活情境着手,合理设计数学问题,引导学生自主参与,切实体验数学与生活间的密切联系,提高学生解决数学问题的能力。 “Compulsory education mathematics curriculum standards” clearly stressed the need to attach great importance to students’ life practice to learn mathematics, understanding of mathematics. Therefore, the teaching of primary school mathematics should focus on familiar life situations from the students, to design mathematical problems reasonably, to guide students to participate in their own work, to effectively experience the close connection between mathematics and life, and to improve students’ ability to solve mathematical problems.
