I took part in "Math Challenge" by Kevin in August. I didn't want to join at first, but my friend invited me to do, then I agreed so as to make a good friend. My classmates and I went to the challenge that night. Kevin asked us to answer a math question and build a tower, which needed knowledge and to practice. We worked together and we finished them in time. Our tower was the highest among twelve towers. How great and beautiful it was! Even we tried our best, we lost and were sad. It was very hard to success. But I believe I will be succeed in the future. It's my feeling. Thanks.
