Description

本实用新型属一种九九葫芦串。
目前,为增加学龄前儿童的学习和娱乐而设计的用品有各种各样,例如专利88204252.1“九九”数码棋、专利88209558.7“九九”数学棋、专利91207460.4乘法口诀仪等,但结构复杂,使用较麻烦,不够直观,不易被学龄前儿童和低年级学生所接受,更难引起学习的兴趣。
本实用新型的目的是提供一种形以葫芦串,用来练习数学乘法口诀的教学用具。
本实用新型由串轴、定珠、转珠及轴帽组成,串轴(1)上有被乘数定珠(2)、乘号定珠(3)、乘数转珠(4)、等号珠(5)、乘积转珠(6)、(7),顶端套有轴帽(8),被乘数定珠(2)及乘号定珠(3)与串轴(1)为一体,乘数转珠(4)及乘积转珠(6)、(7)套在串轴(1)上可转动,等号珠(5)用键紧固在串轴(1)上,被乘数定珠(2)、乘数珠(4),乘积转珠(6)均有1~9个数码,乘积转珠(7)上有0~9个数码及一空位。
本实用新型将九九乘法口诀用葫芦串形式表达,巧妙地把口诀集中在算珠上,通过定珠与转珠在串轴上的转动变化,帮助学龄前及小学低年级学生学习和检验学习的效果,增加了形象感和趣味性,使儿童尽早学习乘法口诀成为现实,并将产生积极的社会效益。
附图说明:
图1是本实用新型结构示意图;
图2是本实用新型结构剖视图。
本实用新型中的串轴(1)、乘数转珠(4)、等号珠(5)、乘积转珠(6)、(7)均可用塑料加工而成,再按图1或图2装配好,转珠(4)、(6)、(7)转动灵活后,在串轴(1)的顶端压上轴帽(8),各数码及符号要清晰,各珠可按需要配上各种迷人色彩,使儿童乐用。使用时,转动乘数转珠(4),利用乘号定珠(3)及等号珠(5)的符号,便可在乘积转珠(6)及(7)上找到答案,使本来枯燥的学习内容,变得富有趣味性,富学于玩,由玩得学。
