星期六 
和孩子们一路前行3今天教学了四舍调商，课前给学生五分钟时间复习和预习。学生的参与度还是很高的。，真奇怪，这学期，还是去年的老师和学生，是什么让大家有一股劲，让课堂变得如此活跃？和往年一样，我在班级黑板的右侧角，开辟了小组学习情况评价栏目，有了比较，就有了动力，每个人都有一颗积极向上的心，不甘心落后，不甘心自己小组的智慧星比别的组少，因此，整个班级都在你追我赶中，有些学生一点不曾磨洋工，或许在我布置预习作业前，就进行了课本预习，不然怎么刚刚布置课本上的计算，有学生就大声回答，“我做好了。“我做好了。”怎样让这些涌在前面的学生安静，正面思考自己的作业？我仔细检查三到五名同学的作业后，说“安静，和你的同学一起检查。”或者穿插一道有些思考难度的作业，让他们静心思考，这样也算是在分层教学吧，一部分学生在板演，一部分在自己的座位上继续，一部分学生在思考他们的“小灶”。
知道四舍之后，除数变小，商会变大，调小减一，学生的计算正确率还不错，课本相应的练习量不大，难度也不深，全是商是一位数的算式，课到最后还有五分钟时间，我迅速从随身带来的补充习题中抽出六道计算，请学生扮演齐练，上讲台的完成一道题目，在座位上的完成两道。针对那些待进生，还是多多让他们扮演，及时了解他们的情况，便于帮助补救。
