计算教学是小学数学的一个重要环节,由于长期重复而又机械的训练,致使学生谈虎色变,大部分学生对计算产生了厌烦心理,造成了准确率低,计算速度慢,方法单一等不良后果。计算是学好数学的基础,计算能力是每个学生必备的数学技能,怎样才能让学生计算准确、迅速而又方法得当,是每位教师必须探索的教学问题。 Computational teaching is an important part of primary school mathematics. Due to long-term repetition and mechanical training, students are discouraged. Most students are annoyed with the calculation, resulting in low accuracy, slow calculation speed and single method. Computation is the basis for learning mathematics. Computational ability is an essential mathematical skill for every student. How to make students calculate accurately, quickly and properly is a teaching problem that every teacher must explore.
