Description

数学教学板
技术领域:本实用新型属于数学教学用具技术领域,具体地讲是一种数学教学板。
背景技术:目前,在数学教学过程中经常的需要在黑板上作图讲解演示,现有技术主要是由教师一手高举固定直尺,一手持粉笔作图,这样操作十分麻烦、费时费力,给教师增加了工作难度。
发明内容:本实用新型的目的是提供一种在数学教学过程中作图操作简便、省时省力的数学教学板。
本实用新型的技术方案是:包括黑板,其特征是在黑板下边缘中段设有伸缩臂,伸缩臂上设有转轴,转轴上设有伸缩尺。
本实用新型的有益效果是:本实用新型结构简单,在数学教学过程中作图操作简便、省时省力,减轻了教师的工作难度。
附图说明:附图1为本实用新型的结构示意图。
图中1、黑板,2、伸缩臂,3、转轴,4、伸缩尺。
具体实施方式:包括黑板1,其特征是在黑板1下边缘中段设有伸缩臂2,伸缩臂2上设有转轴3,转轴3上设有伸缩尺4。在数学教学过程中作图时,调节伸缩尺4作图即可。
