心算是一种只凭思维及语言活动,不借助任何工具的计算方法。心算能提高学生快速计算的技巧,发展学生的注意力、记忆力和思维能力,开发学生大脑的运算和思维潜能。"数学课程标准"提出小学生"要能够正确地进行整数、小数、分数的四则计算,对于其中一些基本的计算要达到一定的熟练程度,并逐步做到计算方法合理、灵活"。学生计算能力的提高与其思维的发展密切相关。因此,我们组织具有丰富教学经验的小学数学教师与教研专家,编写了"小学数学快速心算"丛书。 本书依据数学课程标准,内容与人教版小学数学一年级教材同步,设题形式多样,充分激发学生的学习兴趣,通过练习让学生掌握更多的心算技巧和方法,提高学生快速、准确的心算能力。
