PI (π) Day数学竞赛-我们的π,无所不在的数学

美校宣 CAIS长春美国国际学校

May I ask you a question? How many digits can you recite PI from memory?

考考大家,您可以背到π的第几位?


Maths is full of mystery! On PI Day, March 14, a "PI Day" Competition was held in order to celebrate PI Day and to inspire students' enthusiasm about Maths. CAIS Maths Teachers invited all the MYP and DP students to participate in this event.

数学就是这么充满奥秘!314日,和π3.14一样的日子,这一天为了纪念人类发现了圆周率这个规律,也为了激发学生们对数学的热忱,数学组最强教师团队邀请了所有MYPDP学生参与了一场竞争激烈的πDay 最强大脑比赛。


Simply speaking, we divided students into different groups and they had the competition in rounds. What they gained during the competition was not only speed, intelligence but also team collaboration as well.

简单来说,就是划分小组,分轮竞技。我们的竞赛比速度,比脑力还要比团队合作。 


Students' reflection after the competition: They all agreed that the maths problems of the competition were very innovative. 

"Teachers like to set some tricky questions. We can hardly work them out if we don’t think hard. But in general, it was exciting and full of fun. We really enjoyed it. "

据参赛小组的赛后回顾:竞赛的题目很有新意,但是老师们太喜欢“挖坑”了,很多题目想不到那个点,错失了机会。但是总的来说,真的很刺激,题目很有趣,我们很享受这个过程。 

Teachers' reflection after competition: We really felt happy to see the fierce competition. We also made a Pie, the same sound as π, to celebrate our great subject. We believe that the positive competition and a united team will surely help students reflect themselves. The communication after the competition was also important. Different solutions to the same problem can open up their minds and inspire them to solve problems in flexible ways. 

据数学教师们赛后回顾:我们很很开心能观看孩子们竞争激烈的场面,我们制作了派,和π同音,一起庆祝我们伟大的数学学科。我们认为,良性的竞争和团结的小组氛围一定会带给学生很多反思,竞赛结束后的交流也很重要,同一题目的不同解决方式可以开拓他们的思路带给他们不一样的解题灵感。 

We are sure that you or your friends have complained how boring and difficult Maths is. However, we can hardly explore other fields in the world without the help of Maths.

相信从小到大,您的身边一定有朋友或者同学抱怨过数学是多么难,多么枯燥。可是事实上,对于每一种全新领域的探索都在依赖着这门古老而基础的学科。

 

Maths is the foundation of many subjects such as Physics, Chemistry, Biology and Computer Science. In the long process of the development of the human civilization, Maths has already penetrated every bit of our life. Calculus is used to design the best turning point and time for racing drivers. The golden section ratio has been widely used in the art of photography and paintings. Mathematics modeling helps the supermarket to predict the sales and inventory in different modes……

数学是物理、化学、生物、计算机等多种学科领域的奠基石,在人类漫长的文明进展中,它已经细化到了生活的方方面面,微积分将赛车手的转弯轨道设计成可量化的角度和时间点;黄金分割点被广泛地应用到摄影和绘画的艺术品中;数学建模将超市的库存与销售绘制成可预测的不同模式

Maths emphasizes laws, but there isn’t any pattern behind the decimal point in π. It’s an amazing world, isn’t it?

数学讲究规律,偏巧π的小数点后又没有规律,这真是一个神奇的世界,你说呢?

Congratulations to the champion team and thank you all to the Maths teachers for preparing the PI Day activities and baking the delicious Pie. What will the surprise be that the Maths teachers will bring to us for the next PI Day? Stay Tuned!

恭喜冠军团队们,感谢所有数学组教师准备的π Day活动和可口的派!下次π DayCAIS数学组会带来什么创意呢?敬请期待!
