I joined the first Maths challenge.That was on a saturday night,we class 6 go to the hall to jion the activity.During the activity,I had chance to communicate with kevin.I was a little shy,but the exciting experience is worth to remember all my life.Otherwise,I also looked others work.All of them all so wonderfull that most of them can hold many coins.And the team behind us even held all of the coins.I think they are great.朱惠琴Huiqin Zhu
