在数学教学中,我们摸索出了利用木折尺可以很方便地组成各种平面图形、立体图形等各种教具模型,作一些数学教学演示,进行直观性教学,收到了良好的教学效果。实践证明,妙用木折尺,一物多用,既方便又实用且经济,一举三得。 In mathematics teaching, we explored the use of wooden folding rulers to easily form a variety of graphic models, three-dimensional graphics and other teaching aid models for some mathematical teaching demonstrations, intuitive teaching, received a good teaching effect. Practice has proved that the magical use of wooden folding rulers is a versatile tool that is convenient, practical and economical.
