Abstract

幼儿算术算盘,特点是算盘没有横梁,算盘框内由两部分组成,一部分是四串珠子,配有四则运算标志,可以从事加减乘除四则运算;另一部分有10串珠子,用于当运算的数字稍大时,直观显示出运算过程和结果。可以使幼儿快速掌握算术,既动脑,又动手,生动有趣,并开发幼儿右脑潜能,培养直观思维能力。

Description

幼儿算术算盘
【技术领域】本实用新型涉及一种学习算术四则运算的工具。
【背景技术】按传统方法,幼儿学习算术四则运算,往往不够直观,算出的很多数字,大脑里没有直观的印象;而且一般是动脑运算,很少有动手的,参与性和趣味性不够。
【实用新型内容】本实用新型提供一种学习算术的幼儿算术算盘,它的特征是,算盘框内,由两部分组成:一部分是四串算盘珠,每串算盘珠是9个珠子,算盘框上,加上四则运算标志,可以用于加减乘除计算;另一部分是10串算盘珠,每串10颗算盘珠,可以直观展示计算过程和结果。
本实用新型的优点是,加减乘除法中涉及的数字,列出来一目了然。学生学习时候,不仅动脑,而且动手,增加趣味性且容易吸引学生注意力。而且运算的过程和结果,可以直观地显示出来:例如学生背诵乘法口诀,口诀的每一句,都可以在算盘上,用珠子的数目,直观显示出来。
【附图说明】

图2幼儿算术算盘背面结构图
【具体实施方式】
图一为幼儿算术算盘正面结构图,图中1为算盘框,2是大算盘珠的竖梁,共四根,3是大算盘珠,每串九颗,4是小算盘珠的竖梁,共十根,5是小算盘珠,每串十颗,6是加号,7是等号,加号左侧的算盘珠,和右侧的算盘珠相加,等号后得出答案。9是减号,8是等号,实施运算模式和加号类似。
图二为幼儿算术算盘背面结构图,10是除号,11和13是等号,12是乘号,运算模式和加减法类似。
幼儿算术运算涉及到的比较大的数字,例如背诵乘法口诀,口诀等式中所有的数字,都可以用算盘珠列出来。
