清香“金脑杯”趣味数学竞赛正式拉开帷幕。比赛特邀数学专家、清华大学优秀共产党员、海淀区教学骨干、数学竞赛优秀辅导教师——张波副校长主持。

THISDL Golden Brain Cup Mathematics Competition officially kicked off. The competition was hosted by vice principal Zhang Bo, a mathematics expert, an outstanding communist party member of Tsinghua University, an excellent teacher of Haidian District, as well as an excellent tutor of mathematics competition.

“金脑杯”趣味数学竞赛——促进数学思维能力提升

“金脑杯”竞赛采用小组积分制,共分为三大环节:操作类题目,抢答类题目,擂台类题目。题目广泛涉猎各级各类数学知识及应用,对学生的数学知识,数理思维及综合数学素养有着极高的要求和挑战。

The Golden Brain Cup adopted bonus point system, which consistd of three stages: operation questions, rush answer questions and challenge arena questions. The questions covered all kinds of mathematical knowledge and practice at all levels, which challenged for students' mathematical knowledge, mathematical thinking and comprehensive mathematical ability.

猜谜答题的热身环节后,正式进入动脑动手比试的环节。第一题是如何在不解开绳结的前提下将胶带从环结构中拿出。题目应用了数学拓扑的原理,通过学生不断的动手尝试,以及老师的点拨,各小组都成功的解出了问题,从实践中得到了具象化的数学拓扑经验。

After the warm-up of guessing game, it officially began. The first question was how to take the tape out of the ring structure without untangle the knot. The principle of mathematical topology was applied to the topic,when all groups had successfully solved the problem and gained concrete mathematical topology experience from practice after students’continuous attempts and the teachers‘guidance.

后面的题目紧贴初中重点的平面几何。这类拼接问题不仅考察学生观察力,想象力,更考察学生的数学分析与应用能力。通过厘清分析边关系和角关系,逐渐摸索规律,学生完成拼接的成功率和速度都有大幅提升。

The following maths problems were closely related to plane geometry, which was the key knowledge of junior high school. This kind of problem not only tested students' observation and imagination, but also tested students' mathematical analysis and practice ability. By clarifying and analyzing the relationship between edges and angles, and gradually exploring the rules, students’splicing had been greatly sped up.

抢答类题目是各参赛队战得火热的环节。黄金分割,二次方程,24点,中国剩余定理,面积比等轮番上阵,各队比分交错上升。在张校长的主持引导下,学生的竞争意识转化为了克服难题的勇气和决心,思路不断拓宽,灵感不停涌现,数学技能愈加精进,灵活方法刻入心扉。

The rush answer questions stage was fierce for all teams. A variety of questions covering from Golden section, quadratic equation, 24 points, Chinese remainder theorem,area ratio to others etc raised students‘ interests when teams took turns to play for higher points. Under the host and guidance of principal Zhang, students' competitive spirit had turned  into the courage and determination to overcome problems. Their minds had been constantly broadened, inspiration had been constantly emerging, mathematical skills had become more skillful, while the flexible methods have been engraved into their hearts.

比赛过程中,张校不忘引导学生放开眼界,游戏数学。通过数学史的故事和任务分享,激发学生兴趣,推动学生进一步自主探索数学世界。

In the competition, principal Zhang always guided students to broaden their horizon so that they could played with the maths. Students' interests were inspired in exploring the mathematical world independently through the stories of the mathematical history and tasks sharing.

最后来到擂台类题目,擂台题分值大,难度高,时间短,答对加分,答错扣分。即便面对如此高的风险,以邵明乾为代表的二组的学生依旧勇于挑战,学习的积极性远超往常。最后一题是非常巧妙的一题,既用到了加法竖式,逻辑推理,容斥原理等数学知识,又同时是一道英文字母题,在数学和语言的艺术性上达到完美的平衡。

Finally, the challenge arena questions came. The challenge arena questions stage was challenged by high bonus points in very short time. If students answer correctly, they would get extra points and if they fail, the points would fell. Facing the high-risk challenge, the students of the second group( represented by Shao Mingqian) still showed their courage in longing for exploring more than usual. The last question was a very clever one, which not only covered mathematical knowledge such as addition vertical form, logical reasoning, inclusion exclusion principle, but also formed an English alphabet question, keeping a perfect balance between mathematics and language.

最终,由霍子奥、李汶晓、吴雅清、刘宇轩、李思源五位同学组成的三组获得了本届“金脑杯”趣味数学竞赛的冠军。通过本届趣味数学竞赛,学生们探索了更多类型的数学问题,又一次体会到了数学的趣味性,广泛地应用了不同的数学方法,更深度体验了数学学科的内在知识联系。期待学生们能在关注数学、亲近数学、应用数学解决问题、提升思维能力的道路上越走越远。

As a result, Huo Ziao, Li Wenxiao, Wu Yaqing, Liu Yuxuan and Li Siyuan won the championship of this competition. Through this interesting mathematics competition, students explored more types of mathematical problems, realized the interest of mathematics again, widely applied different mathematical methods, and deeply experienced the internal knowledge connection of mathematics. Students were expected to go further and further on the road of mathematics from paying attention, getting close to solving problems, and at last develop their thinking ability.
