计算能力是一项基本的数学能力,培养孩子具有一定的计算能力是小学数学教学的一项重要任务。数学大纲中明确提出,要使学生能“正确、迅速、灵活、合理”地进行计算。让学生掌握简便运算的方法,是提高学生运算速度的重要途径。一、简算意识的基础1、基本运算达到要求简便运算实际上是建立在口算的基础上,简便运算的最终目的是将复杂的计算转换为简单的口算。因此,口算能力的好坏,决定着简便运算结果是否正确的一个重要方面。
Computational ability is a basic mathematical ability, and training children with a certain degree of computing power is an important task in elementary mathematics teaching. The mathematics curriculum clearly states that students should be able to calculate “correctly, promptly, flexibly and reasonably”. To enable students to master the simple method of operation is an important way to improve the speed of students. First, the basis of a simple summary of consciousness 1, the basic operations to meet the requirements Simple calculations are actually based on the mouth of the calculation, the ultimate goal of simple operation is to convert complex calculations into simple calculations. Therefore, the ability to speak or not determines the accuracy of simple calculations is an important aspect.
