Math Prize for Girls, Part 1



This weekend was the fourth annual Math Prize for Girls competition, which is a math competition for middle and high school girls. Students qualify for the competition based on AMC scores from the previous year. I participated in the first three years of the competition, and this year I was very excited that the competition was held at MIT because I was able to volunteer!

There are several ways to get into Boston from Olin. The easiest way is to drive, but then you have to park, which isn’t as simple. Most people take either the T (Boston’s subway system) or the commuter rail. Olin isn’t conveniently located for any of the stations, though. It’s between a mile and a half and two miles from four different commuter rail stations, and there’s a T station about five miles away. I walked to one of the commuter rail stations. It’s also pretty normal for emails to go out on a list called helpme asking for rides.

I left Olin on Friday afternoon and walked to the Wellesley Hills commuter rail station, which is a twenty or twenty-five minute walk from the West Hall dorms. I took the train all the way to its last stop – South Station. I’m really familiar with South Station because the silver line from the airport runs there. When I got off the train and walked into South Station, I had to try really hard to contain my excitement. It was so familiar and comfortable, and I was that much closer to Cambridge.
I spent the summer of 2011 doing research in Cambridge , which is across the Charles River from Boston and is home to both MIT and Harvard. This was through a camp called Research Science Institute, or RSI. I lived on the MIT campus, so I know it and the area surrounding it very well. Even though I had no interest in MIT, I have lots of friends there, there are certain spots on campus that I love, and I have favorite restaurants and stores throughout Cambridge. Going back to Cambridge for the first time since last February felt like going home.

From South Station, I took the red line T to Kendall Station, which is in Kendall Square, right by MIT. My first stop was the MIT student center, or the W20. There’s an ATM there, and I’m used to getting work done there. I didn’t have any plans until later that evening, so I’d been planning on sitting in the W20 and working. Soon after I got there, though, as I was looking for an open seat, I turned around to see three of my friends who are sophomores at MIT, including Brigitte, whom I call my sister and who was letting me sleep in her room over the weekend.

I went with them back to their dorm, Random Hall, which on a map looks like it’s off-campus. (MIT’s campus is not easily defined, unlike Olin’s.) On the way and at Random, we ran into several people I know – mostly people from camps. Brigitte, one of the counselors from camp, and I went to Thelonius Monkfish to get sushi, and then Brigitte and I walked to Math Prize Games Night.
Games Night first occurred at the second Math Prize, and it definitely strengthens Math Prize. Before Games Night, Math Prize was just a contest in the morning, a lunch, and then an awards ceremony. Girls might talk before the contest or during lunch, but most people only talked to competitors they knew already. Games Night is two hours of food, board and card games, and it gives time for the competitors to actually talk to each other and meet new people as well as for reunions.

Games Night was Part 1 of the Mathcamp reunion. There were about a dozen Mathcampers, both contestants and volunteers, there. I met the 2011 and 2012 campers who were competing, and I also met a 2012 staff member. We told Mathcamp stories from a wide range of years, pressed each other’s noses (Mathcampers have nosefunctions!), played card games, and ate lots of yummy chocolate and fruit.

After Games Night, a group of us walked back to Random. There, we played word games (I think that night it was the one where you find the midpoint of words) and Bananagrams before going to bed. Brigitte hosted three of us, one competitor and two volunteers.

The next day was the contest! I was helping with grading, so I didn’t have to go over to the academic buildings until 11:45. Most people either proctored or helped with registration, and they had to be in the academic buildings between 8:30 and 9:00. I got up with the others and went to the W20, where I ate breakfast, sat on the first floor in my favorite RSI spot, and did reading for anthropology.  It was Saturday morning, so I didn’t think many people would up, but I posted on the RSI 2011 Facebook group anyway, hoping that maybe someone would stop by and say hi. Within ten minutes, one of the Rickoids who had been in both my counselor group and my tutor group came by, and we talked and worked. (He had an essay to write.)

Grading for Math Prize isn’t very difficult. There are four versions of the test with the questions scrambled. There were twelve graders, so we split into four groups of three. All exams were graded by at least two people; if the student had a potentially award-winning score, three people graded the paper. There are twenty questions, and the competitors write in their answers – it’s not a proof contest. The answer is either right or wrong. We say we’ll only take certain forms, but to a certain extent we’re lenient about that. If the question asked for a + sqrt(b) and a student wrote sqrt(b) + a, we accepted that, but if the question asked for a/b and the student wrote a mixed number, we marked the answer as incorrect.

In past years it has seemed like grading took a while, but it went really quickly this year – we were done less than forty minutes after the exams arrived. We spent the time before the exams arrived eating lunch and talking. The graders were a really wide range of ages – long-established math coaches and teachers to a junior in high school (Brigitte’s brother).

The awards ceremony started at 1:45 with a performance by one of MIT’s a cappella groups, the Logarhythms, and a group of MIT cheerleaders. The medals from the 2011 Math Prize Olympiad (a follow up competition to MPfG) were presented, and then there were opening speakers, including Stephen Wolfram and Tom Leighton. The keynote speaker was Esther Duflo, an MIT professor of economics. She talked about the economics of poverty, like whether mosquito nets should be provided for free or if they’re more likely to be put to the best use if people have to pay for them.
After that, there was a round onstage to break ties. When people tie, they all split the cash prizes evenly, but the tie breaks determine who gets which trophies. The tiebreaking problems are easier than the majority of the test problems, so it’s pretty normal for audience members to work out the problems, too. After that, they handed out awards to everyone who got a score of nine or above. Nines or tens were honorable mention, and there were around twenty of those. Five people tied for eighth with scores of 11, two people tied for sixth with 12s, two people tied for fourth with 13s, two tied for second with 14s, and the winner had a 15. (I graded the 15!)

The winner was Victoria Xia, an eleventh grader who goes to Thomas Jefferson (TJ) in Virginia. The people who tied for second were Danielle Wang and Julia Huang, who were second and third place last year, too. The top three (Danielle won the tie) were the same as last year. Danielle was actually the winner two years ago and I think second place in the first year of Math Prize, as well. Both Danielle and Julia are 10th graders. The two girls who tied for fourth are both ninth graders. That means that everyone in the top five should be back next year!

I really hope I can volunteer again next year; I definitely enjoyed grading and being at the awards ceremony!
