Description

小学数学认知时钟
技术领域:本实用新型属于教学用具技术领域,具体地讲是一种小学数学认知时钟。
背景技术:在小学认识时间的教学中,由于时间特有的抽象性使其讲解和练习时都具有一定的难度,特别是对于抽象思维能力还不强的小学低年级学生难度更大,需要用到加法或乘法运算,现有教学中一般采用表盘教具来示教和训练,训练方式单一,没有其他的提示,影响学习效率和教学效果。
发明内容:本实用新型的目的是提供一种结构简单,易于推算,便于学生认知时间的小学数学认知时钟。
本实用新型的技术方案是:包括表盘和芯轴,其特征是在表盘外侧设有滑槽,滑槽内设有滑轮,滑轮上设有转轴,转轴上设有指示针,滑轮上设有多条转杆,转杆上设有对应数字。
本实用新型的有益效果是:本实用新型结构简单,使用方便,易于推算,便于学生认知时间,大大提高了学习效率和教学效果。
附图说明:附图1为本实用新型的结构示意图。
图中1、表盘,2、芯轴,3、滑槽,4、滑轮,5、转轴,6、指示针,7、转杆,8、对应数字。
具体实施方式:包括表盘1和芯轴2,其特征是在表盘1外侧设有滑槽3,滑槽3内设有滑轮4,滑轮4上设有转轴5,转轴5上设有指示针6,滑轮4上设有多条转杆7,转杆7上设有对应数字8。在数学时间教学时,时针一般容易认知,滑动滑轮4指示针6所指的位置,拨动对应数字8便于认知和训练以此加深记忆即可。
