Abstract
GirlsGetMath is a weeklong mathematics summer dayprogram for 9th and 10th grade high school girls in the Providence, RI area.
GirlsGetMath occurs in an encouraging environment that builds young women's confidence in math and science.
GirlsGetMath expands participants' understanding and knowledge of mathematics through computations and experimentations.
GirlsGetMath provides expert mathematical training and mentoring.
GirlsGetMath will become a replicable national model of mathematical outreach for high school girls, with an emphasis on mathematical experimentation.
This fiveday nonresidential mathematics program is open to high school girls from the greater Providence, RI area who will have just completed either grade 9 or grade 10 by July 2015.
GirlsGetMath@ICERM will encourage 20 young women to explore, and invite them to excel in, the mathematical sciences. Accomplished professional women, enthusiastic about serving as career models as well as scientific mentors, will lead the program. Potential topics include: cryptography, the mathematics of voting, image processing, prime numbers and factoring, and fractals.
The goals of the program are:
 to show high school women that the study of mathematics can be exciting, beautiful, and useful
 to build confidence in students' mathematical knowledge through engaging and expert mathematical instruction
 to introduce high school students to a variety of career opportunities in which sophisticated mathematical ability plays a key role
 to emphasize the strategic role mathematics plays for success in STEM careers
 to provide the participants with a support group and expert mentors who are successful undergraduate, graduate students, postdocs, and professionals from the STEM workforce
 to have a positive influence on the way students view their mathematical interest and ability.
Program Details
 Instructors
 The faculty organizers will be joined by undergraduate, graduate students and postdocs who will serve as teaching fellows in the program. Two GirlsGetMath alumni will be chosen to assist during the program as well.**
 Location
 Pandemic permitting, the program will take place at the Institute for Computational and Experimental Research in Mathematics (ICERM) on the Brown University campus.
 Participant Requirements

 Students must not have attended a previous GirlsGetMath@ICERM program (unless they are applying to be an alumni intern  see below**)
 Students must be in the 10th or 11th grade in the fall of 2015 (NOTE: applicants from the canceled 2020 program will automatically be included in the pool of applicants for the 2021 program; there is no need to reapply.)
 Students must live in or near the greater Providence, RI area
 Students must ask one math teacher to submit a letter of reference
 Tuition
 Tuition is $100. Full financial aid is available. Daily lunch included.
 To Apply as a Participant
 Applications are accepted through MathPrograms.org. You will need to create an online MathPrograms cover sheet, answer a series of brief questions, and hit the "Apply" button. You can edit your application up until the deadline. On the cover sheet, where it says "Reference #1", please enter your reference writer's name, email, and affiliation (school). IMPORTANT: Next to your reference's name, click on the box that says "email notify writer on submit"; this will generate an automated email asking your reference writer to submit a letter on your behalf through MathPrograms. Your reference writer should be a current or recent math teacher.
 **To Apply as an Alumni Intern Volunteer
 ICERM will only accept alumni internship applications from the 2019 GGM alumni group. Alumni only need to submit a onepage personal statement explaining why they wish to return as an intern when they apply. No teacher reference is required for alumni interns. Intern applications are accepted through MathPrograms.org.
 Application Deadline
 Applications for the 2015 program are now closed. Applications open in late winter, and the application deadline is midtolate May.

Purpose of Program
Despite the fact that jobs in STEM are multiplying and pay better than other careers, women remain woefully underrepresented in science, technology, engineering and math jobs. Some of this imbalance may be traced back to attitudes about mathematics and sciences in middle school and high school. There is a documented decline in girlsâ€™ positive feels about mathematics beginning in middle school, and from this point forward girls are far less likely than their male peers to choose elective courses in mathematics and the sciences^{[1][2]}. The absence of girls in mathematics and science elective courses is especially severe among lowincome and disadvantaged students. Research has shown that schoolaged girls may not realize that their preferred career choice requires coursework in mathematics and sciences^{[3]}, so these decisions can have long lasting consequences.
GirlsGetMath@ICERM aims to build knowledge and confidence in mathematics ability early in education, ultimately shaping the way the students view themselves and their mathematical interests and potential. The program will:
 Demonstrate through handson activities, games, and computer simulations that the study of mathematics can be exciting, beautiful and useful;
 Introduce the high school participants to a variety of career opportunities for which sophisticated mathematical ability plays a key role, with an emphasis on the central role mathematics plays for success in STEM careers; and
 Provide the participants with a support group of likeminded peers and mentors.
 An outstanding feature of the GirlsGetMath@ICERM program is its commitment to quality. The program content is created by Ph.D. mathematicians who collectively have many years of experience as researchers and educators. The content is chosen to be at the appropriate level for the participants, but at the same time challenging, useful, and engaging to high school students. The Faculty Organizers of GirlsGetMath are college and university faculty in mathematics with experience leading summer mathematics programs for students. The Teaching Assistants are undergraduate and graduate students in mathematics and computer science.
