口算在数学教学中有着重要的作用,它可以培养学生的数感,有助于学生智力的提高,培养孩子的数学思维能力,全面激发左右脑潜能,开发全脑。经过训练,学生可以深刻的理解数学的本质,数的意义,数的运算机理。下面就其重要性及训练方法简单地谈一谈。一、口算,有它独特的意义和价值在《2011版小学数学新课程标准》中,新课标对笔算内容的复杂性和熟练程度要求降低了,减少了整数四则混合运算的复杂性,降低了数的整除等一系列内容的要求,但唯 Mouth arithmetic plays an important role in mathematics teaching. It can raise students’ sense of number, help students improve their intelligence, develop children’s mathematical thinking ability, fully stimulate the potential of the brain and develop the whole brain. After training, students can profoundly understand the nature of mathematics, the significance of numbers, the number of computing mechanism. Let’s talk briefly about its importance and training methods. First, the word count, it has its own unique significance and value In the “2011 edition of the new mathematics curriculum standards for primary school”, the new curriculum standards for the complexity of the content and proficiency requirements reduced, reducing the complexity of the integer mixed four operations and reduce Divided by the number of divisions and a series of content requirements, but only
