Some of our middle school students recently competed in the Xavier High School Math Bowl. All students did well and enjoyed the day.
Special congratulations to Joseph who finished fourth in the individual sixth grade competition and Joseph, Ben, Christopher and Jacob, who finished in fourth place for the sixth grade team competition.
