数学课程标准提倡算法多样化,也强调要重视口算,而且在口算的速度上有一定的要求。因此,算法多样化后应该提倡优化,而且必须优化。只有实施算法优化,学生掌握了高效的计算方法,学生才会有一定的口算速度。 Mathematical curriculum standards to promote the diversity of algorithms, but also stressed the importance of port count, but also in the mouth of the rate of certain requirements. Therefore, the algorithm should be promoted after the diversification of optimization, and must be optimized. Only the implementation of algorithm optimization, students master the efficient method of calculation, students will have a certain speed.
