笔者从事小学数学教学工作近30年,在教学中我发现:数学课堂是否高效,很大程度取决于计算教学是否高效。因为数学计算几乎贯穿整个数学学习过程。学生在计算中出现的错误严重干扰着小学生对数学学习的兴趣以及教师的正常教学,而小学生计算能力的强弱则直接影响着学生的学习成绩 I engaged in primary school mathematics teaching work for nearly 30 years, I found in teaching: Math classroom is highly efficient, largely depends on the calculation of teaching is efficient. Because mathematics almost runs through the entire mathematics learning process. Students ’mistakes in the calculation seriously interfere with the primary school students’ interest in mathematics learning as well as the normal teaching of the teachers. However, the calculation ability of pupils directly affects their academic performance
