第一篇:《四年级数学日记50字》
我喜欢这样的数学课
—— 记—次数学试听课
6月30日 星期六 天气：晴
今天是考试后的第一天，我参加了一次校讯通众享教育的数学公开课，这是四升五的—次数学试听课。
郭老师，站在讲台上阳光帅气！他的课像他的人一样出色而富有魅力！他对我们说：“小朋友，刚刚考试完，让我们好好放松，一起玩吧！玩什么呢，我们就来玩数学！首先请问，谁会乘法分配律？”
我连忙举手回答了用字母表示：“a×b+a×c=a×(b+c)。”“好，那么我出一道题： 9999×2222＋3333×3334
我们拿了题就做，结果四位数乘法根本没学过，我们用乘法分配律进行简便吧，又找不到共同的乘数。1分钟过后，大家没算出来！
于是，郭老师给我们讲了“观察法”：“9999可以分解成3333×3，然后运用乘法交换律，让2222×3，所以这道题可以这样解：
＝（3333×3）×2222＋3333×3334
＝3333×（3×2222）＋3333×3334
＝3333×（6666＋3334）
＝3333×10000
＝33330000
这让我想到大数学家高斯小时候，老师给几个上课说话的同学出的一题是1＋2＋3＋4＋……＋97＋98＋99＋100，这个说其他同学都去直接相加法，而高斯却不动笔，一直观察思考，观察思考，而用了1＋99＝100，2＋98＝100，最后算出5050的结果。
郭老师又给我们出了一道题：“那大家算算333……3（共2012个3）×333……3（共2012个3）等于多少？”
老师又给我们讲了“退回去，找规律”法
3×3＝9
33×33＝1089
333×333＝110889
推出333……3（共2012个）×333……3（共2012个）＝111……1（共2011个）0888……8（共2011个）9
这种方法真得很实用，特别是很多数字运算时
郭老师又说：“大家都知道，四边形具有不稳定性。把一个长方形变成平行四边形，它的周长不变，那它的面积是变小了，变大了，还是不变？”
同学们七嘴八舌的议论，有的说变大，有的说变小，还有的说不变。
郭老师给我们讲了“极端化法”：“可以把它一直拉长，最后把这个平行四边形拉到一条线段上，它的面积肯定变小了！”
郭老师还给我们讲了许多数学趣题，我们越听越有趣，越有趣我们就越喜欢数学！试听课讲完了，我们念念不舍地回家了。路上，我在想：“原来数学这么有趣！我一定会学好数学，将来像我们河南的刘洋姐姐一样为祖国效力！”
