Abstract

本发明公开了一种圆教学用具，其特征在于，在圆环体上均布设有多个通槽，在多个通槽的空隙处分别设有凸起，在多个通槽内分别设有滑块，所述滑块可在通槽内滑动和固定，在其中的两个凸起和两个滑块上设有弹性绳Ⅰ，在其中的两个凸起设有弹性绳Ⅱ。通过以上设置，本发明可在教学中演示圆的各种性质，便于学生直观理解记忆，提高了教学质量。

Description

一种圆教学用具
技术领域
本发明涉及一种教具，具体说是一种圆教学用具。
背景技术
教师在几何教学中，会涉及圆的内容教学，如在同一弧上的圆周角相等、弧长、扇形面积，以及圆的内接四边形、正多边形、圆的性质等方面的教学，只凭讲述比较抽象，难于理解记忆。
发明内容
本发明的目的便是提供一种圆教学用具，以便于学生理解记忆，更好的提高在教学质量。
为了实现上述目的，本发明在圆环体上均布设有多个通槽，在多个通槽的空隙处分别设有凸起，在多个通槽内分别设有滑块，所述滑块可在通槽内滑动和固定，在其中的两个凸起和两个滑块上设有弹性绳Ⅰ，在其中的两个凸起设有弹性绳Ⅱ。
通过以上设置，本发明可在教学中演示弧长、扇形面积，以及圆的内接四边形、正多边形、圆的性质等，便于学生直观理解记忆，提高了教学质量。
附图说明
图 1 为本发明的结构示意图。
图中： 1 圆环体 2、通槽 3、凸起 4、滑块 5、弹性绳Ⅰ 6、弹性绳Ⅱ。
具体实施方式
如图 1 所示，本发明在圆环体 1 上均布设有多个通槽 2，在多个通槽 2 的空隙处分别设有凸起 3，在多个通槽 2 内分别设有滑块 4，所述滑块 4 可在通槽 2 内滑动和固定，在其中的两个凸起3和两个滑块4上设有弹性绳Ⅰ5，在其中的两个凸起3设有弹性绳Ⅱ6。
通过以上设置，本发明可在教学中演示圆的各种性质，便于学生直观理解记忆，提高了教学质量。
