π Day
March 14th
G1-4
As an essential subject, mathematics plays an important role in a child’s life. From primary school to college, math has accompanied almost every child's educational career. It is the Math Week from 11th March to 15th March, and the day, 14th March is designated as π Day since the date is linked to the π.
“π Challenge”, “Math Themed Handbags Design”, “Math Carnival”, a series of math-related activities and games were carried out in each grade which immerse the students in the joy of mathematics learning this week.
On 14th March, teachers and children wore costumes with numbers, and each grade also prepared various of activities to celebrate π Day. The first grade teachers gave each student in the class a quarter of a circle to decorate on their own. They put the quarters all together to make this stunning class or hallway collage. The teachers in second grade hid ten interesting math problems outdoor, the children worked in groups to find and completed together. The Math Carnival in third grade is, Dominoes, Chinese Sliding Blocks and Memory Power Game. They enjoyed these competitions very much. The children of the fourth grade started the "π challenge" finals early in the morning, and the students worked in groups in the afternoon who got an envelope and went outdoors to find various mathematical symbols and graphics according to the questions or instructions in the letter.
The π Day is aimed to stimulate students’ interest in learning mathematics. We hope that every student can truly discover the infinite mystery of mathematics, be willing to explore mathematics, fall in love with mathematics, and apply mathematics in their daily life!
数学是陪伴每个孩子学习与成长必不可少的一门学科，对于提升孩子们的运算能力，激发大脑活力，培养逻辑思维能力，起着非常重要的作用。本学期3月11日到3月15日为数学周，借由数字314，将日期与数学中的π联系，将3月14日这一天定为π日。为了让学生体验数学学习的乐趣，每个年级都开展了一系列与数学相关的活动和游戏。“背π挑战”“设计数学主题的手提袋”“数学嘉年华”等，都让学生在这一周沉浸在数学学习的欢乐中。
3月14日，老师和孩子们都穿上了带有数字的服装，每个年级也准备了各种形式的活动来庆祝π日。一年级的老师为每个孩子准备了四分之一圆的纸张，孩子们为它涂画，画好后老师们将这些五颜六色的1/4圆打散拼成一幅不规则的贴画；二年级的老师则是先把十道趣味数学题藏在户外，小朋友们分组合作找到后一起完成；三年级的数学嘉年华，为学生准备了华容道、多米诺、记忆比赛三个数学游戏，让孩子们通过小组活动、双人活动和个人学术活动体验数学游戏的乐趣；四年级的孩子们一早就开始了“背π挑战”的决赛，大家都为了一块好吃的“pie”争先恐后挑战，下午学生们分组领到一个信封，按照信中的问题或提示，去户外寻找各种数学符号、图形。
π日这天，以“知识性”“实用性”“趣味性”的活动形式，激发学生对数学的兴趣，寓教于乐，让孩子们学数学、用数学、玩数学，激发了孩子们强烈的求知欲，让孩子们感受到数学的魅力与学习数学的乐趣。希望每一个学生都能够真正发现数学的无穷奥秘，乐于探索数学、爱上数学、运用数学！

“Ring—!” The students swarmed in like a pack of bees, running and yelling. What was happening? Something exciting, happy, and fun—the Math Bazaar!
“We are going to have a Math Bazaar, where all of you are going to sell things. Use discounts, activities, or whatever you can do, to attract people to come buy your things,” the math teacher explained. After hearing that announcement, the students were buzzing with excitement.
Before the Math Bazaar officially began, students started to tear off the packages of their food, stationary, or whatever items they were going to sell. Advertisements had already begun a day before, and students were determined to be the one who made the most money. This Math Bazaar would be helpful for learning how to sell things in the future. It would also help provide money to donate to charity.
“Come and buy our things! It’s very cheap!” All types of voices mixed together, advertising for their own stand. Break time made the classrooms even more crowded. People from other blocks and classes all came to buy things.
It was definitely a great lesson and experience for the students. The Math Bazaar was a great success, and it was fantastic.
下课铃一响，教室里、走廊里，到处都是激动的学生。这是同学们期待已久的数学集市！
前几天，数学课上学生们提前得知此事。数学老师解释了这次活动要干什么，课后，所有人都非常激动激烈的讨论着期待着。
集市开始前，所有人都迫不及待的将准备好的食物包装袋撕开，一阵阵香喷喷的味道传来。而关于集市的广告和宣传，早在前一天就已经开始了。老师们和同学们都非常期待这次活动，学生们下定决心要努力挣到最多的钱，去帮助更多的人！这次活动主要是要同学们学会怎样买卖、合理打折等商业技巧。这跟同学们数学课上正在学的东西很有关联。寓教于乐，在玩中学。
两堂课中间的休息时间使走廊里和教室里挤满了喧闹的人们，也有很多其他班的同学来买东西了。活动结束后，同学们将部分收入捐给了慈善组织。
同学们在活动中学到了很多买卖的方法。这次的数学集市十分成功，相信同学们都很有收获！

What is pi (π)? Pi is a tool for communicating and rejoicing in mathematics. It represents not only a math constant close to 3.14 but also every SHSIDer’s passion toward exploring the beauty of math. On 14 March 2019 (3.14) students celebrated this number.
During the first CAS period, students of grades seven and eight watched fun math videos in homerooms. These videos displayed ingenious application of math on daily lives and interesting math problems. To some students, regular math classes may have arid circumstances, but this special “math lesson” was able to grab all students’ attention and convey the fun knowledge to them. Some topics included Schrodinger’s Cat, Fibonacci Sequence, and infinity.
Then came the more exciting second CAS period. Every seventh or eighth grade homeroom had a math-related activity that encouraged students to use their math skills to solve the problems. All the rooms were crowded with intelligent young mathematicians, competing against each other to extract the essence of the problems. Some activities were 24-point calculation, Sudoku, board games, π decimal-recitation, and Crazy Math problem-solving. The picture full of love to math was magnificent and luxuriant.
Time passed quickly, and many students complained about the short duration of the mirthful time. Looking at the stamps on the pi-day passport, batches of memories flowed by students’ minds. It is an unforgettable day of math!
什么是pi（π）圆周率？这问题也许不难，但在3月14日这一天，它成为了一个帮助我们用数学的独有语言去交流、谈笑的助手。它不仅代表了近似值为3.14的数学常数，还代言了所有上中国际部学生对于探索数学的无限热情。
下午第一节CAS课上，七、八年级的学生们在各自教室里观看了许多有趣的数学视频。这些视频展示了一些巧妙的数学应用与问题解法，引起了不少同学的赞叹。也许对于一些学生来说，平常的数学课程略显枯燥，不过这一次特别的数学课堂，吸引了所有人的注意力，并授予他们那些有意思的知识点，诸如“薛定谔的猫”定律、斐波那契数列的神奇和无限的奥妙。
随后的第二节课，便是学生们期待已久的数学探索活动。每个七、八年级的教室都有一个特定的活动，等待着好奇心和好战心强的学生前来挑战、讨论。所有的教室顿时簇拥着许多小小数学家，以聪明的才智相互对决，一起吸取那些挑战的精华。趣味活动包括了24点计算、数独、棋牌游戏、圆周率小数背诵和“疯狂数学”挑战。所有的活动绘制成了一幅壮观而富有生气的图片。
不过，快乐的时光总是短暂的。许多学生都遗憾地说活动时长太短，不能尽兴探究。看着通过挑战得到的那些印章，一波波美好的回忆掠过我们脑中。真是一个好不充实的数学节日啊！
Pudong Campus
From March 11th to March 15th, our Pudong students celebrated the remarkable Math Week. In this week, a variety of math fantastic activities and games were carried out. Our lower graders enjoyed their math activities such as Pi Word Challenge, Scavenger Hunt, Sudoku, while upper graders focused on more challenging events, like Presentations of Mathematicians and Bag/T-shirt Design of Pi Elements. 
The most exciting part in this week was the Pi Day. It is well known that Pi Day is celebrated on March 14th around the world. Pi is the symbol used in mathematics to represent the ratio of the circumference of a circle to its diameter — which is approximately 3.14. On the afternoon of March 14th, all of our Pudong students took part in the Pi Day Carnival with great enthusiasm. Students celebrated this day by dressing up as mathematicians creatively and went around to experience different math events. People enjoyed a game called “Where is the Time” in Class1-1, which required a candidate to find numbers related to the clock time in classroom. Some of our students chose to play Math Board Game and Tangram in Class2-1 and Class2-2. Games such as Rounding Bingo in Class 4-2 required participants to calculate intensively in seconds. Admittedly the atmosphere was tense when the competition began, however, all students tried every effort to get higher scores and win more medals.
Although the Math Week comes to the end, Pi Day is a wonderful opportunity for our little math enthusiasts to understand more math concepts, experience the glamor of math and challenge themselves. Hopefully they will continuously play more math games, learn more about math and practice more in the future!
3月11日至3月15日，春光明媚，草长莺飞。经过老师和同学们的精心筹备，浦东校区的数学周活动拉开了序幕，多种多样、妙趣横生的数学游戏和活动牢牢地吸引了大家的眼球。一二年级在数学课上开展了丰富的活动，比如搜索“Pi”打头的单词比赛、数学寻宝、数独等；三至五年级也不甘落后，推出了数学家演讲比赛以及π元素手绘拎袋、手绘T恤等更富有挑战性的活动。
本周，最激动人心的时刻莫属我们的圆周率日了。众所周知，国际圆周率日即每年3月14日，圆周率是圆的周长与直径的比值，一般用希腊字母π表示，约等于3.14。3月14日下午，全体浦东学生以百分百的热情参与到数学嘉年华的活动中。当天，同学们身着和数学有关的服饰，在浦东各大教室穿梭，体验各种有趣的数学互动项目。每个游戏项目区，人头攒动，同学们个个乐在其中。比如，在1-1班，参赛者体验了一把“时间在哪里”，这个小游戏需要大家在教室里找到隐藏的数字，以对应时钟上的时间。2-1和2-2班分别开展了数学桌游和数学七巧板活动，4-2班则进行了“凑整数”比赛，此项比赛需要每一位同学认真计算，绞尽脑汁，才能与众多参赛者一决高下。数学嘉年华活动，使原本枯燥的数学知识变得生动起来，同学们在数学领域不断超越自我，感受到了数学的巨大魅力。愿他们今后继续尽情玩数学、学数学、用数学！
