一、要充分认识培养计算能力的重要性培养学生的计算能力,是小学数学教学的目的之一,教师必须有足够的认识。有些教师对培养和提高学生的计算能力重视不够,没有让学生去发现计算的规律和兴趣。这是培养和提高学生计算能力的一大障碍,必须除之。计算能力,是学生必备的能力。数与计算在日常生活、工作和学习中有广泛的应用。现实世界从数学的角度来看,主要是数、量、形三个方面,而计量又离不开数与计算,形体大小要量化也离不开 First, we must fully understand the importance of training to develop the ability to train students in computing power is one of the purposes of primary school mathematics teaching, teachers must have sufficient knowledge. Some teachers did not pay enough attention to cultivating and improving students’ computing ability, and did not let students discover the laws and interests of calculation. This is a major obstacle to developing and enhancing students’ computing power and must be divided. Computational ability, is the ability of students essential. Number and calculation in daily life, work and study have a wide range of applications. The real world from the mathematical point of view, mainly the number, quantity, shape of the three aspects, and measurement can not be separated from the number and calculation, body size to be quantified also inseparable
