一年级的计算课。尤其需要通过让学生动手操作寻求算理,亲身经历新知识的形成与发展过程。然而,在很多数学课堂中。我们经常会看到“形”和“数”脱节的现象,为了操作而操作,动手操作的实效性没有得到很好的体现。基于此,通过我自己执教的几节一年级的计算课,分别是《5以内的加法》、《9加几》、《十几减9》,谈谈我在一年级计算教学当中是如何将动手操作的有效性落到实处的。
First grade calculation lesson. In particular, it is necessary to experience the process of formation and development of new knowledge by letting students seek the arithmetic by hands-on operation. However, in many math classes. We often see the “shape” and “number” out of line with the phenomenon, in order to operate and operate, the effectiveness of hands-on operation is not well reflected. Based on this, several first-grade computing lessons taught by myself are “additions within five,” “plus nine,” “ten minus nine,” and talk about how I calculated in first grade computing The effectiveness of hands-on practices.
