Students can Zoom into a live class and will be guided by a dedicated TA. There will be some instructor interaction, too, but limited interaction with in-person students. Students will receive the same assignments as the in-person students.

In 2025, we began participating in high school math competitions. Anyone can join our math team class—even if you are not officially selected for competitions, you will gain valuable experience in mathematical problem-solving and contest strategies. To join the NYMC team at competitions, we have to check if you are allowed to compete against your school's team, if it has one.

There will be a supervised lunch period from 12:00 pm to 1:00 pm in which students must bring lunch and drink. Students are NOT allowed to leave campus to purchase lunch.

Competition Geometry (Sunday, July 13): Competition Geometry: We will cover topics such as Ceva's Theorem, Menelaus' Theorem, Routh's Theorem, Stewart's Theorem, Shoelace, Mass Points, Heron's Formula, Power of a Point, Ptolemy's Theorem, and Pick's Theorem. Target Audience: Advanced students in HSB level.

Recursion (Sunday, July 20): Recursion: Problem solving often requires a starting point such as building a table, starting small, and creating similar examples. Recursion is about turning difficult problems into pattern recognition problems instead. Target Audience: 8th Graders and above.

Divisibility, Bases, and Modular Arithmetic (Sunday, July 27): Divisibility, Bases, and Modular Arithmetic: The foundations of number theory rely on modular arithmetic. Many competition problems will use modular arithmetic in many different ways. This workshop acts as exposure to what types of problems may be given, and will focus on identifying uses for modular arithmetic in competition settings. Target Audience: 8th Graders and above.

Counting and Probability (Sunday, August 3): Counting and Probability: Combinatorics and probability go hand in hand. In many competitions, combinatorics is one of the primary problem topics due to it's versatility. Target Audience: 8th Graders and above.

AMC 8 Prep: The AMC 8 course is designed to help middle school students learn the skills and tricks required to succeed on the AMC 8. The sessions will focus on building a competition-based numerical intuition to solve problems efficiently. Note that AMC 8 for middle schoolers differs from the AMC 10 & 12 offered to high schoolers, so please be mindful during registration.

AMC 10 Prep: In this course, we will cover some of the main topics necessary to do well on the AMC 10. We will work through AMC 10 problems and identify the main topics a competent mathlete should master. These topics include Probability, Counting, Elementary Number Theory, and Geometry, among many others.

Graph Theory: Say at least six people are at a party - it turns out that at least three people at the party must all be mutual strangers, or mutually have met before. In this workshop we will look at this and similar results in the context of graph theory. Join us to learn what a “graph” is, and then to explore some interesting questions related to graph colorings and graph matchings. Target audience: Middle School students.

Advanced Contest Topics: This mini-camp is focused on understanding how to approach difficult competition problems with a different lens. In particular, we will look at problems ranging from the Downtown Mathematics Invitational, NYCIML, and AIME. Students are heavily encouraged to qualify for HSA before attending this mini-camp.

Introductory Proof Writing: This one-day mini camp will cover the basics of proof-writing to get students familiar with different types of proofs, misconceptions, and get students started with writing their own proofs to problems. The target audience is late middle school/early high school level.

Cryptography and "Secret Codes": Ever wanted to send hidden messages or crack secret codes? In this mini camp, you’ll learn classic ciphers like Caesar and Vigenère. We’ll also look at the historic Enigma machine, why it was so difficult to break, and how mathematicians eventually cracked it. Finally, we’ll start to dig into modern cryptosystems and talk about how math keeps our private information safe today. Through challenges and puzzles, you’ll see how math has shaped the world of secret communication and test your own codebreaking skills! Target audience: Elementary School and Middle School students.

Vieta's Formulas and a New Approach to Quadratic Equations: Course Objectives: 1. Understand Vieta's formulas for quadratic and higher-degree polynomials. 2. Explore applications of Vieta's formulas in problem-solving. 3. Learn Professor Po-Shen Loh's methodology for solving quadratic equations without memorizing the quadratic formula. Target audience: Students who have covered Algebra 1

There will be a supervised lunch period from 12:00 pm to 1:00 pm in which students must bring lunch and drink. Students are NOT allowed to leave campus to purchase lunch.

Infinity and Beyond: Advanced Math Workshop for Girls: This is a three-week workshop. HS workshop/mentoring dates: March 2, 9, 16. MS workshop/mentoring dates: March 23, 30, April 6. Maximum student enrollment in each class is 8.

Curious to learn (even more) math? Wondering what studying math might look like in college (and beyond)? Come join us as we cover some topics (I find interesting) which you (hopefully) haven’t seen before - if these topics aren’t new to you still feel free to come, and maybe you can teach us something.

This workshop is lead by Ms. Teresa Pollard. Bio: Teresa is an alumna of NYMC who derives great enjoyment from doing math, learning about math, and sharing it with others (among other things like reading, drawing, and walking around pretty places). She recently graduated from NYU, where she majored in math with a minor in philosophy - during her time there she worked as a tutor for the math department, and she remains heavily involved in NYU’s Math Society. While outside of NYU she managed to fill all her summers with some kind of math, and has participated in REUs at CMU and OSU on projects relating to (a combination of) analysis, number theory, combinatorics, and logic. At present she hopes to pursue her PhD in mathematics, and is currently waiting to hear from graduate programs - however in the meantime she is very happy to be back at the NYMC.

The goal of these workshops is to explore math, but also to explore how such math is done - hinting at what you may see if you continue to pursue math. There will also be opportunities to talk, if you’d like to speak with someone who majored in math, and is (at present still) planning to become a mathematician - hoping to see you there!

HS Workshop: Perhaps you’ve heard that there are “different sizes of infinity” - one way to begin exploring this idea is by placing it in the context of sets. In this series of workshops we will begin by introducing some basic set theory, which allows us to reason about infinities in a rigorous way - within this context we can show that there is a sense in which there are just as many rational numbers as integers, while the set of real numbers is strictly “bigger.” With the language of set theory in place, we can also explore some more (finite) properties of sets - for example, we may look at combinatorial questions which can be asked about families of sets, or we could look at “good ways” to sample elements from sets, with applications in some basic data science. [Directions for the class will be up for discussion.]

MS Workshop: Bored with all the games you know - or curious to explore the math behind them (or possibly the math behind some simpler games)? This series of workshops will explore some basic (primarily combinatorial) game theory - after setting things up, we will analyze some of these games (such as Nim), and (whether or not there are) strategies to win them. [Direction for the class will again be up for discussion. In particular, if students have particular games they are curious to study - possibly including SET - or would like to learn about more traditional “game theory,” the instructor would be happy to do so.]

Mentoring hours are from 11:30am to 12:00pm, and 1:00pm to 1:30pm.
