珠算是以数学原理为基础,以算盘为计算工具,用算珠运算的独特计算技术。珠算式心算(简称珠心算)是在大脑中以算珠表象为载体,运用珠算法则进行心算的方法,俗称“在脑中打算盘”。珠心算的操作是一个多种感觉器官、运动器官协同作用的过程。计算时,需一边瞬间记数,一边模拟拨珠,一边珠像内化,眼、耳、口等器官的密切配合,它同时协同思维力、记忆力、注意力、空间想象力等来完成运算任务,有利于促进学生大脑发育,提高智力水平。下面仅就“满五加”一课来谈谈对 Abacus is based on the principles of mathematics to abacus as computing tools, abacus calculation with a unique computing technology. Abacus calculation (Abacus calculation) is in the brain to calculate Abacus as the carrier, the use of bead algorithm is the method of calculating, commonly known as “in the brain intent plate.” Abacus calculation operation is a variety of sensory organs, sports organs synergistic process. When calculating, you need to momentarily count, while simulating the beads, one side of the beads as internalization, eyes, ears, mouth and other organs in close cooperation, it also coordinate the thinking power, memory, attention, space imagination to complete the computing tasks , Is conducive to promoting students’ brain development, improve intelligence level. The following is only “full five plus ” a lesson to talk about right
