浅议初中数学圆的基本性质的复习

A Brief Review on the Basic Nature of Junior Mathematics Circle

圆这一几何图形,本来是我们日常生活中早已熟悉的,甚至可以说是司空见惯的图形,学生们多少都应该有一些感性认识,虽然司空见惯,但是一拿到数学中来研究,因为它的性质之完美性和复杂多样性,很多学生仍然会感到学起来费劲,本文针对圆的对称性,提出一个教学设计,供同行共勉。

This circle geometry was originally familiar to us in our daily life.It could even be said to be a common pattern.Students should have some perceptual knowledge.Although they are commonplace,they are used to study in mathematics because Its perfection and complexity of nature,many students will still feel difficult to learn,this paper aims at the symmetry of the circle,put forward a teaching design for peer encouragement.
