在初中数学教学中,数字和图形是有利于教师教学和学生学习的重要因素,把二者结合起来,就是数形结合,利用这种思想来解各种几何问题,比如平面几何的大题。本文主要阐述运用数形结合在初中教学中的作用和应用,把数形二者结合运用到教学中,使之发挥重要作用,达到教学目的。
In the mathematics teaching of junior high school, figures and figures are important factors conducive to teacher teaching and student learning. Combining the two is the combination of numbers and shapes. This idea can be used to solve various geometric problems, such as the big problem of plane geometry. This article mainly elaborates the function and application of combination of number and shape in junior high school teaching. It uses the combination of number and shape in teaching to make it play an important role in achieving teaching goals.
