3月14日是圆周率纪念日，也称为π Day，因为圆周率的近似值π≈3.14。
3月6-14日，广州暨大港澳子弟学校（ASJ）小学部第一届数学节π Day圆满举行。这场盛宴通过让学子们了解π的数学史，立足学科核心素养，激发孩子的兴趣和自我驱动力，培养学子的终身学习力，成为善于探究的学习者。
ASJ PYP日常的数学节着重培养学子们在数学学科中的八大能力：空间想象能力、推理能力、数学交流能力、“数感”、信息处理能力、批判思维能力、融合创新能力与综合分析能力。
G1数学大富翁比赛
数的世界永无休止，
小小黑板，承载对数学之美的追求。
G1初赛着重培养孩子的推理能力以及信息处理能力。通过轻松快乐的数学大富翁比赛，寓教于乐，寓学于趣，寓教于心，为未来的继续学习奠定深厚的基础。
决赛举办了紧张刺激的抢答比赛，这一环节不仅考验学生对知识点的掌握程度，同时也考验学生的反应力，能否优先抢答回的题目，最后决出三强。
G2过三关斩六将
公式推导，黑白交错。
是教导，更是教学相长的交流。
G2着重培养孩子们的“数感”，在收获快乐的同时也提高了数学核心素养，巩固了数学知识。
第一关就是记忆圆周率，在认识了π这个无限不循环小数后，我们鼓励孩子用不同方式记忆圆周率的数值，提高对数字的敏感度。这对于孩子们来说无疑是个考验记忆力的大难关，但很多孩子都富有挑战精神，一遍又一遍地尝试，最终有孩子挑战成功，背出了小数点后前50位数字！
在第二关游戏“一米叠叠乐”中，孩子们需要搭建立体图形并使其高度接近一米。比赛中，孩子们不仅要搭得稳，还要搭得“准”，大家在稳定立体图形之余，还要判断搭建的高度是否已经达到一米了。这小小的比赛需要孩子们熟悉各立体图形的特点和对米的概念，培养了量感和空间感，同时也考验了大家的耐心和坚持。
最后结合加减混合运算这一章节的学习，我们开展了第三关比赛活动“Making 314”。通过观察数的特点和估算，孩子们很快就能运用加减混合、连加或连减计算出314，提高了计算能力和数感。
G3叠卡牌游戏
3.1415926......π，
数学的美妙与奥秘，
在生活中随处可见随时可解。G3着重培养孩子们空间想象能力和数学交流能力，G3孩子体验了叠卡牌游戏，通过折叠、堆高等形式考验学生对基本模型的认识。活动还没开始，G3的孩子们就摩拳擦掌，早早准备好卡牌练习。
比赛时孩子们都很认真，有的孩子虽然卡牌一次次倒下，还是会不断重复，坚持到最后一刻，这样的毅力值得鼓励和表扬。一场看似简单的游戏，也考验了孩子们的耐心、毅力和坚持，培养孩子们成为善于交流者。
G4数学单词拼写比赛
圆形，有且仅有一个圆心。
每位ASJ孩子，都是独特的个体。G4着重培养孩子们的信息处理能力。G4的孩子们带着紧张的心情迎来了数学单词拼写比赛。为了这场比赛，孩子们提前就开始背数学单词。
进入复赛的孩子更是把“速度与激情”体现的淋漓尽致。这场单词的较量考验的不仅是对数学单词的记忆，同时也考验着大家的反应、灵活的大脑和敏捷的身体、以及稳定的心理素质。
孩子们都表现得很棒，相信这次认真备赛参赛的孩子对单词的熟悉度又更近了一步，为今后学习英文数学奠定了基础。
G5“一站到底”
π有无尽的数字，孩子有无限可能的未来。决定自己什么样的，只有自己。G5着重培养孩子们的批判思维能力、融合创新能力，G5的孩子经历了一场“一站到底”的比赛。从一起认识π的由来，到随机分组、组别淘汰赛，最后迎来冠亚军组对决。孩子们在比赛过程中也学会了如何通过团队的力量。解决问题，深化理解。在日常学习生活中能够及时反思，稳步向前。
一边了解π的由来，一边认真记笔记。开始分组了，每个人抽一张刮刮卡，刮开就能看到自己是哪一组了。谁才是那个对的眼神呢？
在组别淘汰赛环节和巅峰四强环节，孩子们一张张认真答题的脸让老师们印象深刻。队友团结合作，攻克一个个不同的数学问题，团队精神展现得淋漓尽致。
G6把π Day变成π Week
我们习惯不懈怠，一直努力。
每位孩子都是独立的圆，
走的每一步，
都在成就未来。G6将π Day做成了π Week。着重培养孩子们的融合创新能力，学生每天都能在π day Special发现到新的逻辑思维题。起初孩子们对于英数的拓展题不太敢轻易尝试，但是后来通过慢慢的摸索，第二天、第三天就有越来越多的孩子愿意去尝试，蜂拥而至的找老师讲解题目，最后甚至非常意外的获得了奖项。我们希望通过不断地引导、鼓励，让孩子们不仅仅在课堂上对数学保持热情，而是在生活中，认真对待每一件小事，都会感受到生活给我们带来的惊喜！成为一位全面发展的学习者！
另外，数学单词竞赛也是六年级π day活动的第二个重头戏。学生如火如荼地享受π day的活动，并通过两项活动的累积积分，激烈角逐出一，二，三等奖。
颁奖仪式努力终将获得回报
3月14日，ASJ小学部举行了π Day颁奖典礼，为在活动中展现出思考能力、拼搏能力和坚持的学子颁奖。
在颁奖仪式开始前，老师们准备了几道数学抢答题，G1-G6的孩子都十分踊跃参加。思考，不分年龄，永不停歇。ASJ小学部学子在抢答游戏中，也可以发现自己在思考中的不足之处，日后加以注意，成为更加全面思考的人。
March 14 is Pi Day, also known as π Day, because the approximate value of pi π≈ 3.14.
From March 6th to 14th, the first ASJ PYP π Day was held. By understanding the origin of π and the relevant mathematical history, children focus on stimulating children's interest in learning and self-motivation, and pay attention to the bits and pieces of children's daily life.
G1Math Monopoly Game
The G1 preliminary round held a relaxed and happy math monopoly competition, allowing students to fully feel the fun of playing middle school mathematics, not only allowing them to feel the fun of the game, but also helping them consolidate the knowledge of mathematics they had learned, laying a deep foundation for future learning.
The final held a tense and exciting quiz competition, which not only tested students' mastery of knowledge points, but also tested students' reflexes, whether they could prioritize the questions they answered back, and finally decided the top three.
G2Challenging All the Way Through
The Math Festival competition ended successfully, and the children of G2 actively participated in the game activities, which improved their mathematical literacy and consolidated their mathematical knowledge while gaining fun.
The first level is to memorize pi, after understanding the infinite non-cyclic decimal of π, we encourage children to memorize the value of pi in different ways to improve their sensitivity to numbers.
In the second game, "One Meter Stacking", children need to build three-dimensional shapes and make them close to one meter tall. In the competition, the children must not only build steadily, but also build "accurately", in addition to stabilizing the three-dimensional shape, they must also judge whether the height of the building has reached one meter.
Finally, combined with the study of the chapter of addition and subtraction mixed operations, we launched the third level of the competition activity "Making 314". By observing the characteristics and estimation of numbers, children can quickly calculate 314 using addition and subtraction, addition or subtraction, and improve their numeracy and number sense.
G3Card Stacking Game
G3 children experienced a card stacking game, which tested students' understanding of basic models through folding, stacking and other forms. Before the event started, the G3 children were ready for card practice early.
The children were very serious during the competition, and a seemingly simple game also tested the children's patience, perseverance and persistence.
G4Math Word
Spelling Competition
The children of G4 were nervous about the math word spelling competition. For this game, the children started memorizing math words in advance.
The children who entered the rematch embodied "Fast and Furious" to the fullest. This word contest tests not only the memory of mathematical words, but also everyone's reflexes, flexible brains and agile bodies, and stable psychological quality.
G5"One Stop to the End"
The G5 kids experienced a "one stop to the end" race. From the origin of knowing the π together, to the random grouping, group elimination, and finally ushered in the champion and runner-up group showdown. The children also learned how to make themselves better through the strength of the team.
While understanding the origin of Π, take careful notes.
In the group knockout round and the peak four finals, the teachers' faces were deeply impressed by the serious answers of the questions. Teammates worked together to solve different math problems, and the team spirit was vividly displayed.
G6Turn π Day Into π Week
G6 kids turned π day into π week. Students can discover new logical thinking problems in the π day corner every day. As soon as class starts, children rush out of the classroom and gather in the math corner, either to understand or discuss enthusiastically. After figuring out the answer, I can't wait to rush in the direction of the office as soon as possible and present the fresh results to the teacher to obtain a point "badge" that highlights the honor.
In addition, the Math Word Contest is the second highlight of the Grade 6 π Day activity. Students are in full swing to enjoy the activities of π day, and through the accumulation of points in the two activities, fiercely compete for the first, second and third prizes.
Award Ceremony
Hard Work
Will Pay Off
On March 14, ASJ Elementary held the π Day Award Ceremony to present awards to students who demonstrated their ability to think, work hard and persevere.
Before the award ceremony, the teachers prepared several math questions, and the G1-G6 children participated enthusiastically. Think, regardless of age, never stop. ASJ Junior School students can also discover their own shortcomings in thinking in the quiz game, pay attention to them in the future, and become more comprehensive thinkers.
