试论数学计算教学“五步曲”

Discuss on"Five Steps"of Mathematics Calculation Teaching

计算贯穿数学教学的始终,又与生活息息相连,是数学教学中的重点内容。在数学计算教学实践中,教师要讲清算理,生成算法,鼓励学生算法多样化,对比优化算法,让学生学会迁移方法,活学活用,还要善用错例,分析悟法,并精练勤练,持之以恒,使学生养成习惯,从而提升学生的计算能力。

Calculation runs through the whole process of mathematics teaching and is connected with life and interest,which is the key content of mathematics teaching.In the teaching practice of mathematical calculation,teachers should make clear calculation theory,generate algorithm,encourage students to diversify algorithm,compare and optimize algorithm,let students learn migration method,learn to use flexibly,and make good use of wrong examples,analysis and understanding method,and practice hard and persevere,so that students can develop habits,so as to improve students'calculation ability.
