数学教学中,计算能力直接影响着学生的数学成绩。一份数学试卷一般包括四大板块,即概念、计算、操作、实际应用。除了基本操作外,其余三个板块都离不开计算。因此,能否提高学生的计算能力,将直接影响数学教学效果的好坏。口算既是笔算、估算和简便计算的基础,又是计算能力的重要组成部分。一年级作为起始年级,学生口算能力的高低将直接影响以后各年级计算能力的
In mathematics teaching, computing power has a direct impact on students’ math performance. A math test paper generally includes four sections, that is, concept, calculation, operation, practical application. In addition to the basic operation, the remaining three sections are inseparable from the calculation. Therefore, the ability to improve students’ computing ability will directly affect the quality of mathematics teaching. Mouth counting is not only the basis of pen calculation, estimation and simple calculation, but also an important part of the calculation ability. The first grade as a starting grade, the level of students’ ability to count will directly affect the ability of each grade
