格雷戈里●柴延说：数学是一门奇妙而疯狂的学科，充满了想象力、幻想和创造力，它不受物质世界的细节所限制，只受我们内心灵光的制约。

“正话反说”，是一场考验大家专注力、逆向思维的挑战。帮助大家提高数感，让数学变得更加有趣和生动！

“感知时间”，一场关于时间与数学的美妙邂逅。我们希望通过有趣的数学游戏和实验，让大家深刻感受到时间的流逝与数学的关联，让大家更好地理解时间的概念和体会我们所处的空间。

在图形猜猜猜的环节中，培养孩子成为一名交流者（Communicators），如何准确高效的表达交流图形的特征；在记忆大比拼的挑战中，孩子们都是一名名小小的冒险者（Risk-takers），挑战自己的记忆，呈现出思维与语言的碰撞。

采访R同学，他表示数学节活动很好玩，尤其是感知时间，又紧张又有趣。很喜欢这样的活动，非常期待下次的数学节活动！

高段数学节的另一个活动--“数学周挑战”，则是特别侧重探究者（Inquirers）和勇于冒险者（Risk-takers）的品质。活动共持续了一周，学生每天都需要主动到不同地方发现题目，解题完毕去老师处“惊心动魄”核对答案，这需要学生有冒险者的勇气。这些题目既考验了他们的是否能灵活运用数学知识，锻炼了他们的解决问题的能力。通过解题，学生们积极探索解题方法，培养了学生独立探索的意愿和能力。

“一站到底”活动，是一场考验学生数学知识储备和应变能力的智慧盛宴。这不仅是对学生数学能力的挑战，更是对逻辑思维、快速反应能力、团队合作的锻炼（communicators）。而“比大小”活动，则是一场数学与策略的完美结合。在这个环节中，你将与同学们一起比较数的大小，对团队的决策能力和抗风险能力有着很大的考验，培养学生的策略思维和竞争意识（balanced）。

活动参与者之一的学生S表示，活动对他来说是一次很大的挑战，但也是一次很有意义的经历。“这次数学挑战让我感受到了学习的乐趣，我喜欢在解题过程中不断探索，寻找解决问题的方法。”他说道，“希望下次可以持续久一点，让我们有更多的时间去挑战自己。”

Gregory Cheyenne says: Mathematics is a wonderful and crazy subject, full of imagination, fantasy and creativity, which is not limited by the details of the material world, but only by the light of our inner spirit.

The two wonderful activities, "Talking Back" and "Sensing Time", fully reflect the IB cultivation goals, which are to cultivate children to be Thinkers, Inquirers, and Reflective.

"Forward and Backward", a challenge to test everyone's concentration and reverse thinking. It helps everyone improve their number sense and makes math more fun and lively!

"Sensing Time", a wonderful encounter about time and math. We hope that through interesting math games and experiments, we can give you a deep sense of the connection between the passage of time and math, so that you can better understand the concept of time and appreciate the space we live in.

In the graphic guessing session, children are trained to become Communicators, how to accurately and efficiently express and communicate the characteristics of the graphic; in the Memory Challenge, children are Risk-takers, challenging their memories and presenting a collision of thinking and language.

Interview with R. He said that the Math Fest activities were fun, especially sensing time, which was intense and interesting. He enjoyed this activity and is very much looking forward to the next Math Festival activity!

"Codebreaker" allows students to become a codebreaker, swim in the sea of numbers, experience the connection between numbers and letters, and after a series of operations, find the letters corresponding to the numbers in the codebook, which can be converted into words and then into sentences, combining numbers and language. Students go on to experience math as the language of the world, the poetry of the universe, the art of abstraction, and the aura of wisdom. Students are trained to be Knowledgeable.

Another activity of the Upper School Math Festival, the Math Week Challenge, focuses specifically on the qualities of Inquirers and Risk-takers. The week-long program required students to take the initiative to go to a different place each day to discover a problem, and then to go to the teacher's office to "thrill" them with the answer, which required the courage of risk-takers. These problems tested their ability to use math flexibly, and honed their problem-solving skills. By solving the problems, students actively explore solutions and develop a willingness and ability to explore independently.

The "One Stop to the End" activity is a feast of wisdom that tests students' math knowledge and adaptability. It is not only a challenge to the students' math ability, but also an exercise in logical thinking, quick reaction ability, and teamwork (communicators). The "compare size" activity is a perfect combination of math and strategy. In this session, you will work with your classmates to compare the size of numbers, which is a great test of your team's decision-making ability and risk tolerance, and develops students' strategic thinking and sense of competition (balanced).

Student S, one of the participants of the event, said that the event was a great challenge for him, but also a very rewarding experience. "This math challenge made me feel the fun of learning, and I like to keep exploring the process of solving problems and finding ways to solve them." He said, "I hope that next time it will last longer and give us more time to challenge ourselves."
