Were you at the event? If so, it would be super helpful if you could fill out the event feedback form. We’d love to hear from everyone: competitors, coaches, chaperones, volunteers, spectators… anyone who attended!

The 2nd annual WBGMC will take place on Sunday, January 17th, 2021!

The Williston Math team is excited to announce the first Whitaker-Bement Girls in Mathematics Competition!

Our vision is to bring together 100+ elementary and middle school girls for a day of fun, centered around mathematics, empowerment, and growing a strong female-centric mathematics community!

The event will take place on Sunday, January 19, 2020 at the Williston Northampton School. Team check in will begin at 8 a.m. and the event will conclude at 3:30 p.m.

The event program is online right here!

This free event is being built by members of Williston’s math team.

The competition will be comprised of individual and team rounds. There will be two competitive tracks: one designed for elementary school students and one for middle school students.

Teams will be comprised of a maximum of four students. Schools/organizations are welcome to send more than one team. We have space for up to 150 competitors.

Individuals and groups of fewer than four people can register to compete. These registrants will be given the option to be joined with other similar groups to form teams of four.

Individual and team prizes will be awarded to top three finishers in both the middle and elementary school divisions.

Lunch is included for all participants and coaches. Additionally, the first 100 registrants will receive a free competition t-shirt!

Registration will close on Monday, January 6, OR when we hit out cap of 150 competitors.

    b) Be female or non-binary in gender identity.
    c) Be in grade 9 or below OR under 15.5 years of age on the day of the competition (January 19, 2020).

  • Where can I register?

  • Do participants needs to submit a completed waiver?

    Yes, they do.

    A waiver completed must be submitted for each competitor before they are allowed to compete.

    The waiver is online here in two formats. Both are the same: PDF, DOCX

    Scans of completed waivers should be emailed to Josh (jseamon@williston.com).

    While completed waivers can be submitted the morning of the event during registration, it’s preferred if the forms are emailed in before the event.

    Chaperones should make sure they are carrying a hard copy of all waivers with them at the event.

  • How can I submit team rosters? (Due Monday, 1/13/20)

    Please use this online form to submit your team roster(s) by Monday, 1/13/20.

  • Is there an age minimum?

    No, there is not, but keep in mind that problems in the elementary school division will be geared towards students in fifth and sixth grade.

  • Does someone who wants to compete need to be connected to a school or other organization?

    Nope! Individual competitors or groups of competitors can attend without being connected to a school or any other organization. They will need to have a chaperone, which could be someone like a parent or guardian or one of the competitors.

  • Which schools are competing? (Last updated 1/9/20)

  • Whitaker-Bement?

    Sarah Whitaker and Dorothy Bement founded the Northampton School for Girls in 1924. In 1971 the school merged with Williston Academy to become the Williston Northampton School. You can read more about Sarah Whitaker and Dorothy Bement right here.

  • Does my team need an adult chaperone?

    Yes! All organizations must have at least one adult chaperone with them at all times. If an organization is bringing more than one team, they are only required to have one adult chaperone, although one per team is recommended.

  • How difficult are the competition problems?

    We’re aiming for the difficulty of competition problems to span elementary school topics through a maximum difficulty of AMC 8 problems. Some challenge problems will work to push students to the level of AMC 10.

  • Can I see some example problems?

    Sure thing!

    Here you go: Problems, Solutions

    All of our example and competition problems are written by members of the Williston Math Team!

  • I want to sign up but I don’t know how many competitors we’ll be bringing. What do I do?

    When registering, teams only need to provide an estimate of their number of competitors. Teams will have until Monday, January 13, to finalize their rosters.

  • Where does the event take place?

    The Whitaker-Bement building located right here on the Williston Northampton School campus. The street address is 51 Park Street.

  • Where can I park? (UPDATED 1/17/20)

    Due to the inclement weather, ALL parking must be done in the Reed parking located right here across the street from The Schoolhouse building (19 Payson Ave, Easthampton, MA 01027).

    Drop off CAN still be done right next to the Whitaker-Bement building, but all vehicles will need to park in the Reed lot.

    Full-sized busses will not be able to drop off at WB. They will need to drop off on the main quad and then get instructions from security on where to park.

    Ms. Sokolow presentation to coaches and teachers is titled “Fractals: Artistic Mathematics and Shifting Perspectives of Mathematicians”. Her presentation to students is titled “A Discussion of Dimension: What is the 4th dimension and what happens if you fall into a black hole”.

  • How will the Individual Round work?

    The Individual Round is a 50-minute, 10-problems test where all answers are single values (i.e. short answers). The point weights for each problem are indicated on the exam.

  • How will the Team Round work?

    The Team Round is a 60-minute, 10-problem test where all members of a team work together. The point weights for each problem are indicated on the exam.

  • What’s the Guts Round?

    The Guts Round is an 60-minute team event with 42 short-answer questions on an assortment of subjects, of varying difficulty and point values. The problems are divided into sets of three. The point weights for each problem are indicated on the exam.

    All teams gather in one large room. At the starting signal, each team sends a runner to an assigned problem station to pick up copies of the first set of three problems. As soon as a team has answers for one problem set, the runner brings the answers to the problem station and picks up the next set of 3 problems. It is not expected that students will finish all the problems. Grading is immediate and scores are posted in real time.

  • How will teams be ranked at the end of the event?

    A teams’ final team score will be calculated as a sum of their scores from all three rounds.

  • Are calculators allowed? How should answers be formatted?

    Any calculator without a QWERTY keyboard is allowed.

    Answers must be exact or have 4 (or more) significant digits, correctly rounded.

  • Who will be awarded prizes?

    The top three finishers in all four divisions (Elementary and Middle School, Team and Individual) will receive prize plaques.

  • How will teams send in their rosters?

    Teams will use an online form to submit their rosters. The form will be posted by early December. The form will collect participants names, T-shirt sizes, dietary restrictions, and some additional miscellaneous information.

  • Do you have some promo materials we can use to spread the word about the event?

    We sure do!

    Here is our press release and here is a super-awesome poster!
