1.认真、细心的计算习惯数学课中的计算教学是小学低年级数学的重要而长期的内容,加减乘除计算循环反复,给教师提供训练学生细心的好机会。比如,在三位数加减三位数验算学习中,出现了竖式数位对不齐、忘记进位、验算方法不对、写错答案等多种错误。教师要引导学生看到 1. Conscientious and Computational Habits Computational teaching in math class is an important and long-term content for mathematics in the lower grades of primary school. Repeated addition, subtraction, multiplication and division cycles provide teachers with a good opportunity to train their students carefully. For example, in the three-digit addition and subtraction three-digit check learning, there has been a vertical digit mismatch, forgot carry, check the wrong way, the wrong answer and other mistakes. Teachers should guide students to see
