计算具有基础性和工具性,它是人们生活、学习、科学研究和生产实践中应用最广泛的一种数学方法,。如果学生在小学阶段就能熟练掌握计算方法,并形成一定的计算能力,无疑将终身有益。计算方法的习得、计算能力的提高、计算技巧的形成都是通过反复练习实现的,而练习的设计安排应有针对性,有层次性,形式多样的练习才能保证在不加重学生负担的前提下取得良好实效。那么,如何在教学计算练习课时构建一个充满生机和活力的数学计算课堂呢?笔者认为应从以下几个方面寻求突破:
Calculation is basic and instrumental. It is the most widely used mathematical method in people’s life, study, scientific research and production practice. If students can master the calculation method in primary school and form a certain amount of computing power, they will no doubt benefit themselves for life. The acquisition of calculation methods, the improvement of calculation ability, the formation of calculation skills are all realized through repeated exercises, and the design of exercises should be targeted, structured and varied in practice to ensure that without prejudice to the burden on students Achieve good results under. So, how to construct a dynamic and dynamic math classroom in teaching calculation practice class? I think we should seek breakthrough from the following aspects:
