explore our CAMPUS

What's cool about our campus is that it's spread out over seven acres in Philadelphia's historic neighborhood of Germantown. The buildings are an eclectic mix of old and new, a unique look and feel more consistent with a college campus. With three gyms, three auditoriums, a student center, numerous open, green spaces and nine classroom buildings, it's a place worthy of adoration and exploration. The Meetinghouse, at the center of it all, provides a beautiful and spiritual focal point.

The math program strives to equip each student with the skills to think logically and analytically and to articulate strategies for solving problems, particularly those related to math and science. We seek to develop a student’s understanding of algebra and other mathematical concepts throughout the curriculum. Topics in each subject are explored visually, symbolically, and verbally. Scientific and graphing calculators and various software applications are used as instruments for exploration and deeper understanding. Our aim is to encourage students to become confident in their math abilities and to recognize math as a powerful subject and tool. The standard mathematics progression is rigorous, leading to advanced courses in calculus and statistics for juniors and seniors. In addition, accelerated courses are offered at each grade level, starting in eighth grade. These courses move at a faster pace and explore topics in greater depth and breadth.
