2011版《义务教育数学课程标准》指出了几何直观的作用,即借助几何直观可以将复杂的问题简单化,突出形象,以助于探索出解决问题的方法,形成思路。结合小学生的思维特点,我们在实际教学中要挖掘出几何直观的教学价值,让学生借助于形象思维来形成自己的思考,并降低问题难度,突破原有的认识,具体可以从以下几方面着手:厘清数与形,找到联系点华罗庚先生说:“形缺数时难入微,数缺形时少直观。”这句话精准地诠释领悟数与形之间的依托关系,在教学中我们要找
2011 edition of the “compulsory education mathematics curriculum standards” pointed out the role of geometric intuition, that is, with geometric intuition can simplify complex issues, highlighting the image to help explore the ways to solve the problem, the formation of ideas. Combined with the thinking characteristics of primary school students, we should excavate the teaching value of geometry and intuition in practical teaching so that students can form their own thinking through image thinking and reduce the difficulty of the problem and break through the original understanding. Specifically, we can start from the following aspects : To clarify the number and form, find the point of contact Mr. Hua Luogeng said: “When the number of missing form is difficult to micro, when the lack of shape less intuitive.” This sentence accurately interpret the relationship between the number and form of understanding, in teaching We are looking for
