《义务教育数学课程标准(2011年版)》指出:“培养运算能力有助于学生理解运算的算理,寻求合理简洁的运算途径解决问题。”从中可以看出培养学生运算能力的重要性。教学中,教师应审视算理和算法之间的内在联系,科学施教,让学生在理解、领悟的基础上学会灵活地运用法则和运算律正确地进行运算,使算理的学习与算法的抉择有机融合。从而,使得计算教学充满灵性、
“Compulsory Education Mathematics Curriculum Standard (2011 Edition)” points out: “The ability to develop computing power helps students understand the arithmetic of computing and seek a reasonable and concise way of computing to solve the problem.” "It can be seen from the importance of training students in computing power . Teaching, teachers should examine the internal relations between arithmetic and algorithm, teaching science, so that students understand and comprehend on the basis of learning to use the law and arithmetic law to correctly operate, so that the arithmetic of learning and algorithm Choice organic integration. Thus, making computing teaching full of spirituality,
