同学们,你们听过数学日记吗?会不会写呢?今天就让我们一起来学学吧!首先让我们一起来欣赏灏灏同学的数学日记:2013年9月7日星期六晴今天,天气可好了。一大早我就跑去表弟家,因为表弟要在课上表演一个节目,介绍年月日,所以姑姑把我这个大哥哥邀请过去一块儿练习。练习开始了,姑姑扮演年,我扮演月,表弟扮演日。由于我早已学过年月日的知识,所以主要由我来介绍,我边做动作边说:“大家好,我是‘月’。我有一个姐姐叫‘年’,还有一个弟弟名叫‘日’。” Classmates, have you ever heard a diary of mathematics? Will you write it? Let’s learn together today! Let’s start with a math diary of our students: Today is the weather Okay Early in the morning I ran to my cousin, because my cousin had to show a program in the class, introducing the year, month, and day, so my aunt invited me to practice the big brother together. Practice began, aunt played the year, I play in the month, cousin to play day. Since I have already learned the knowledge of the years, I mainly introduce me. As I say, “Hello everyone, I am the month.” I have a sister named ’year’ and a younger brother named ’day’."
