珠心算假期练习1(初级).doc

致家长的话尊敬的家长：你们好！首先感谢你们一直以来对我班珠心算教学工作的大力支持和努力配合。在家长和教师的指导下，小朋友们取得了可喜的成绩！心理学家认为：“儿童的智慧在儿童的手指尖上，小朋友动手就是动脑”。珠心算的训练正好是通过双手协调拨珠来进行的。利用算盘的直观来引导幼儿进行实际的双手操作，使幼儿通过双手的活动，起到手脑并用的效果，促进幼儿左右脑平衡发展。同时快速记数、认数，计算准确、迅速要求幼儿眼耳手口共同参与，有效地培养幼儿记忆力、理解力、注意力、思维能力，强化了意志，增强分析、判断能力。然而，珠心算的教学要求教师精讲，儿童多练，才能实现珠算向珠心算的转化。愈是纯熟的珠算技巧，愈发挥高超的心算程度。所以为了使我们的小朋友学得更好，更精，我们特地制定了以下一份练习资料供家长和幼儿作为平时练习的题型进行反复练习。要求家长妥善保管这份资料，让幼儿学到哪练到哪，每天坚持练习15分钟。在题量上家长可以从中挑选1020道题来让幼儿做，在熟练以后再由易到难、由少到多进行练习，以免让幼儿感到压力过大而影响学习的积极性。而对于幼儿每一次取得的进步，家长都要给予及时的肯定和鼓励，以增强幼儿学习的主动性。再次谢谢家长们的配合！
