River Valley Math Challenge

來學校接兒子，他去參加RV math challenge! 他們學校得到冠軍！他在電話中和我說，trophy 很大！接到他時看到奬座，果然很大！
RIver Valley math challenge is a team competition. Pinche told me the champion school can keep the trophy for a year. If the school is champion for 3 consecutive years, they can keep it permanently!!😁
