今天的数学课，学的是有关“实际与计划”的应用题。由于这些内容距离学生的生活实际比较远，我生怕学生听不懂，就列举了许多例子。下了课，象往常一样，我坐在桌前先批改一些学习有困难的学生的作业，这样他们能提早把作业订正好。批着批着，发现从第一排的后面不时传来一阵? Today's math class, learning is the “practical and planning” application questions. Since these contents are actually far from students' lives and I am afraid that students do not understand them, I cite many examples. After class, as usual, I sat down at the table and criticized homework assignments for students who had difficulty in learning so that they could correct their homework early. Approved the batch and found from the back of the first row came from time to time from time to time?
