Abstract

本实用新型提供了一种小学生数学演算装置。 该装置的特点是:在一演算板的无数个小圆孔下面, 分别装有带旋钮的数字转盘和带旋钮的运算符号转 盘。小学生用手拨动各个有关旋钮就能进行小学数 学四则运算练习。

Description

本实用新型涉及一种小学生数学演算器具装置,该装置特别适用于小学生进行数学四则运算的练习。
现市场上虽有不少帮助儿童,学生学习识数,计算的玩具,数数具,但适用范围小,计算方法单一,操作呆板,携带不便,有的家里虽备有辅导孩子学习的小黑板,但家长学生都不习惯板书,并且写时满手沾染粉笔灰,擦时粉笔灰尘飞溅,影响家庭卫生。
为了帮助、辅导小学生进行数学四则运算的练习,使知识性趣味性学习融为一体寓休息娱乐之中,特设计一种小学生数学演算器装置,学生在校学习,回家自学,家长辅导均能适用。
本实用新型小学生数学演算器装置是这样完成的,现结合附图说明。
用木材或塑料制(注)一长方形(或其它形状)的演算板面(一),在演算板面上钻一较大孔和三组(各组含3孔以上)等距,直径的小孔,每个小孔下边都分别安装一个带有旋纽并能转动的小园盘(二),每个小园盘的边上都依次注有等距离,大小的阿拉伯数字0123456789并留一空白处,较大孔下边安装一个带有旋纽并能转动的小园盘(三),该园盘的边上注有等距,大小的+-×÷运算符号并留一空白处,根据运算需要,用手拨动每个旋纽时,各孔就会呈现你所需要的数字和运算符号,而整个板面小孔呈现的数字和运算符号就构成了一道你所需要进行运算的算式,另在每个小孔上边分别注上个、十、百、千……定位标记,整个板面设计成可供学生看书的看书器,并设有温度计,电子表钢笔的放置处,板面背面还设有课程表,日历卡的装贴处,整个板面、转盘、注字全部彩色。
现结合算式:9×9=81进行演算举例。
先用手拨动左边个位小孔下边的旋纽,使此孔呈现被乘数9;再拨动运算符号小孔下边的旋纽,使此孔呈现×号;拨动正中间个位小孔下边旋纽,使此孔呈现乘数9;最后分别拨动右边十位,个位小孔下边旋纽,使十位小孔呈现8,个位小孔呈现1,这样整个板面小孔呈现的数字和符号就构成了一道9×9=81的算式,其它不呈现数字孔全部拨到空白处,如要进行两位数以上的四则运算操作方法同上。
如果家长辅导学生时,家长只拨出题部分旋纽,答案部分旋纽由学生拨;也可两学生进行互出题演算;学龄前儿童可用它作为识数,数数练习。
附图一是演算板。附图二是数字转盘。附图三是运算符号转盘。附图四是演算器正面图。附图五是演算器背面图。
