Welcome to Trapezium Math Club

Trapezium Math Club

Trapezium Math Club is a math enrichment program designed to build strong math skills for students in grades k-5. Many of our students arrive at Trapezium hating math and leave the program loving it. Our students tend to stay with the program throughout elementary school and are prepared to take the most rigorous math courses in middle and high school.

Using our team-based sports model, coaches meet with students once per week for 1.5 hours to prepare for ongoing math events.

Each term at Trapezium is dedicated to a theme. We use this theme to teach children very hard math in preparation for two things: our ongoing math reasoning contests (conducted during club time) and a public culminating event dedicated to our theme. See below for descriptions our Fall, Winter and Spring themes.

Math Expo

Math Expo

The Fall event culminates with a Math Expo which gives visitors an opportunity to participate in the games and activities that are part of the Trapezium math club experience.



Our Winter theme is “Mathemagic.” From January through March, students prepare for the culminating Mathemagic event, a variety show which infuses impressive acts of mental math with humor and audience participation. Family and friends are encouraged to attend and cheer on the kids as they show off their new math skills!



Our Spring theme is dedicated to preparing students for the annual MonsterMathathon. In this “Amazing Race” inspired event, student teams of equal math level compete by using math to solve clues found along an outdoor course. Last year, MonsterMathathon was held at The Philadelphia Art Museum and Boathouse Row.

PSSA Prep for 3rd and 7th Grade


Trapezium now offers PSSA Prep courses for Philadelphia families interested in Masterman for 5th grade and Special Admission High Schools like Central. Our courses focus on the four areas tested on the PSSA (Numbers and operations, Geometry, Algebraic Reasoning, Data Statistics and Probability). We teach the content as well as test taking skills and strategies needed for success on the test (with the Trapezium Math Club spin!)
