估算是根据具体条件及有关知识对事物的数量或算式的结果作出大概推断或估计。它在很大程度上体现着一种近似的口算,它也是计算能力的重要组成部分。学生估算能力的培养是学习的需要,是适应实际生活的需要,也是训练思维和发展智力的需要。那么如何在小学数学教学中培养小学生的估算能力呢?
Estimates are based on specific conditions and knowledge about the number of things or the result of a general estimation or estimation. To a large extent, it embodies an approximate port count, which is also an important part of computing power. The cultivation of students’ estimation ability is the need of study, the need of adapting to real life and the need of training thinking and developing intelligence. So how to train pupils in elementary mathematics teaching estimation ability?
