数形结合是初中数学教学中十分重要的一种教学思想,在初中数学新课标中,一共有“数与代数”“空间与图形”“统计与概率”“实践与综合”四个部分,每个部分都需要数与形两个元素。只有将两者结合起来,巧妙应用于数学课堂,学生才能在学习过程中开拓思路,融会贯通,对数学知识才能理解更深刻。一、以形补数,直观易懂在教学过程中,我们会遇到一些表达数量关系的、较为抽象的理论知识,这时就可以将其转化为几何图形,用直观的图
Combination of number and shape is a very important teaching idea in junior high school mathematics teaching. In the new curriculum standard of junior high school mathematics, there are altogether “number and algebra”, “space and graph”, “statistics and probability”, “practice And synthesis ”four parts, each part requires two elements of number and shape. Only by combining the two can be applied cleverly in mathematics classrooms so that students can develop their thinking in the process of learning and find a better understanding of mathematical knowledge. First, to form the number of completions, intuitive and easy to understand In the teaching process, we will encounter some expression of the number of relations, the more abstract theoretical knowledge, then you can convert it into a geometric figure, with an intuitive map
