计算在数学中占有很大的比例,数学知识的学习几乎都离不开计算。因此,计算教学是小学教学的重要部分。新课程对计算教学进行了大幅度的改革,对计算教学的价值重新定位:计算教学不再是单纯为了计算而计算,它把计算教学和应用数学相结合,要求学生的计算学习活动要从单纯地依赖模仿和记忆,转化成一个生动、主动和富有创造性的过程,让学生学习生活中的数 Calculation occupies a large proportion of mathematics, almost all of mathematics knowledge can not be calculated. Therefore, the calculation of teaching is an important part of primary school teaching. The new curriculum has revolutionized computing teaching and repositioned the value of computing teaching. Computing teaching is no longer calculated solely for computing. It combines computational teaching with applied mathematics, and requires students to study their computing activities from simple Relying on imitation and memory, into a vivid, proactive and creative process that allows students to learn life’s number
