Since its founding, the Wahaha Math Team has held weekly Sunday tutoring sessions led by volunteer teacher Xiaowei Sun, who guides students through the world of mathematics rain or shine.

娃哈哈青少年俱乐部的数学小组自成立以来，每周日由孙晓卫老师义务地给孩子们上辅导课，风雨无阻地带领孩子们在数学的国度里尽情翱翔。

The annual Knights of Pi Math Tournament is one of Washington State's most challenging math competitions, drawing nearly 150 teams from grades 5 through 8 across the greater Seattle area. On December 12, 2015, Wahaha sent a 6th-grade squad — Albert, Alan, Lenci, and Ryan — to compete for the very first time. Despite facing formidable established teams, the students were thoroughly prepared by their teacher and showed no nerves. They defeated all competitors to win 1st place in the 6th-grade group division! When "Wahaha" was announced in the Newport High School auditorium, the entire audience erupted in applause, and many curious students and parents came to ask about this "Wahaha" school or organization. This was Wahaha's first appearance on a math competition podium — and it is only the beginning. Under Teacher Sun's guidance, we are confident the team will keep achieving even greater results.

每年一度的Knights of Pi Math Tournament 数学竞赛，是华州难度较大的数学竞赛之一，吸引了西雅图周边从5年级到8年级的近150支队伍参加。2015年12月12日，娃哈哈数学小组派出了由Albert ,Alan, Lenci和Ryan四个人组成的六年级团队代表Wahaha首次参赛。尽管强队如林，但老师精心指导孩子们认真准备，丝毫不怯场。最后力克众传统强队，摘取了六年级组团体赛第一名的桂冠！当Wahaha的队名在偌大的Newport High剧场里响起时，全场掌声雷动！同时也有不少好奇的学生和家长们过来询问Wahaha是个什么样的学校或组织。这是Wahaha代表队第一次出战并出现在数学竞赛的领奖台上，但这还只是个开始，相信在孙老师的带领下，Wahaha代表队会越战越勇，继续取得更多更骄人的成绩！
