小学数学教学大纲对计算能力的要求是“正确、迅速、合理、灵活”,其中计算正确是基本要求,合理、灵活是较高的要求。一、认真审题,提高计算的正确性计算要正确,首先要养成认真审题的好习惯。一要看清题目的每一个数字、运算符号;二要按照运算法则,确定先算什么,再算什么;其次解题的书写格式要整洁、规范,并进行认真检验,确保计
Primary mathematics syllabus requirements for computing power is “correct, rapid, reasonable and flexible,” which is the basic calculation of the correct requirements, reasonable and flexible is a higher requirement. First, conscientiously examining questions and improving the correctness of the calculation The calculation is correct. First, we must develop a good habit of carefully examining questions. First, we must see clearly the subject of each number, operator symbols; second, according to the algorithm, to determine what to count, then what; second problem solving the writing format to be neat, standardized, and carefully tested to ensure that the total
