计算在小学数学教学中占有很大的比例,是学生必需掌握的数学基础知识、基本方法和必要的基本技能,是数学学习与数学能力发展的根基。但长久以来计算教学得不到师生的青睐。老师不喜欢上计算教学,觉得计算教学过程枯燥无味,只要告诉学生运算顺序以及容易出错的地方即可。学生也不喜欢上有关计算教学的课, Computation occupies a large proportion of primary school mathematics teaching, which is the basic knowledge of mathematics, basic methods and necessary basic skills that students must master. It is the foundation of mathematics learning and development of mathematical ability. However, teaching and learning have not been favored by teachers and students for a long time. The teacher does not like to calculate the teaching, that calculation of teaching process boring, just tell the students the order of operations and error-prone place. Students also do not like to spend on teaching courses,
