计算是数学知识中的重要内容之一,数学计算能力是一项基本的数学能力,包含了计算的准确率和正确率两方面的计算能力,是学习数学和其他学科的重要基础。在小学数学教材中计算所占的比重很大,尤其是低年级,学生计算能力的高低直接影响着学生学习的质量,因为数学中有些概念的引入需要通过计算来进行;数学中解决实际问题的解题思路、步骤、结果也要通过计算来落实。几何知识的教学要涉及周长、面积、体积的求法,这些公式的推导与运用同样离不开计算,至于简易方程、比例和统计图表等知识也无不与计算密切相关。可见学生的计算能力是至关重要的。所以提高学生的计算能力,就要从低年级的学生入手,认真、严格的训练,这样才有助于培养学生的数学素养,有助于培养学生解决问题的能力,有助于树立学生认真、细致、耐心、不畏困难的品质。
Computation is one of the important contents of mathematical knowledge. Mathematical calculation ability is a basic mathematical ability, which includes the computing ability of accuracy and correctness of calculation. It is an important foundation for learning mathematics and other disciplines. The calculation of primary school mathematics textbooks accounted for a large proportion, especially in the lower grades, the level of computational ability of students directly affects the quality of student learning, because the introduction of some concepts in mathematics need to be calculated; mathematical solution to practical problems Problem-solving ideas, steps, results must be calculated to implement. The teaching of geometric knowledge involves the calculation of the circumference, the area and the volume. The derivation and application of these formulas can not be separated from calculation. The knowledge of simple equations, proportions and statistical charts are all closely related to the calculation. Visible students’ computing power is crucial. So to improve students ’computing ability, it is necessary to start with the students in the lower grades, serious and rigorous training, which will help to develop students’ mathematical literacy, help students develop their ability to solve problems, help to establish students seriously, Meticulous, patient, fearless quality.
