Abstract

本发明为一种算术运算规则演示工具，其结构包括底盘、演示条、演示珠三部分组成，三部分组成可拆卸；底盘最多可规则排布10个演示条；每个演示条有10个空位，最多可容纳10个演示珠。演示条最多容纳10个演示珠的设计，用于演示十进制规则；底盘和演示条可分离，可演示运算中十位数的加减；演示条和演示珠可分离，可演示运算中个位数的加减。本发明基于儿童认知水平，以十进制概念和规律为基础，培养儿童识数和运算能力，更直观地帮助儿童树立正确的数量和算术概念，在动手总结规律的过程中可培养儿童的探索精神。

Description

一种算术规则演示工具
技术领域
本发明涉及小学数学教育领域，具体涉及一种算术规则演示工具。
背景技术
识数和加减乘除的四则运算在幼儿和儿童教育中，占据重要地位。受幼儿和儿童认知水平限制，树立正确的数量和加减乘除的概念并非易事。教授儿童识数阶段，多采用数手指、小棒等实物形式；教授儿童运算阶段，多采用灌输“凑十法”等技巧，其不足之处在于：通过数手指或数小棒识数，儿童较难掌握数量中十进制中“十”的涵义，就难以理解后续运算中的技巧；仅仅灌输运算的技巧，不够形象，不利于儿童掌握四则概念，同时这种直接告知结论的方法，不利于儿童科学精神的培养。
发明内容
为了解决上述问题，设计了一种符合十进制规则的可拆卸的算术规则演示盘。本发明将抽象的十进制下识数和运算规则形象化，解决了儿童识数和运算过程存在的困难。
为达到上述目的，本发明的技术方案是这样实现的：
提供一种算术演示工具，其结构包括底盘、演示条、演示珠三部分组成，三部分组成可拆卸；
本发明的一种改进是，所述的底盘有10个凹槽，最多可规则排布10个演示条；
本发明的一种改进是，每个演示条有10个空位，最多可容纳10个演示珠。
本发明的有益效果是：演示条最多容纳10个演示珠的设计，用于演示十进制规则；底盘和演示条可分离，可演示运算中十位数的加减；演示条和演示珠可分离，可演示运算中个位数的加减。可帮儿童树立正确的数量和运算概念。
附图说明
图1为算术规则演示工具示意图
具体实施方式
识数：摆满演示珠的演示条表示十位数，未摆满演示珠的演示条中演示珠的数量表示个位数。
运算：摆满演示珠的演示条的增减，可演示运算中十位数的加减；演示珠的增减，可演示运算中个位数的加减。
