Beginner Circle is our class for the youngest students. Our primary goal in this circle is to develop students' reasoning and creative thinking abilities and to explore mathematics outside school arithmetic. However, we will be working on number sense and advanced math skills as well. We will engage kids in discussions, problem solving, hands-on activities, and games.

This class is for students who are not only interested in mathematics but are mature and focused enough to actively participate for the entire duration of a class (90 minutes).

Course Details: School-year long, 30 weekly sessions, 90 min each. Placement Test is required. This circle is designed for advanced 3rd graders and 4th graders.

Our unique curriculum combines visual problem-solving methods, hands-on math, logical reasoning, and engaging discussions. Our students will learn how to approach unusual word problems, competition problems, logic problems; they will learn about cryptography and ciphers, combinatorics, binary numbers, fractals, and much more. The homework is assigned after each class.
This class requires developed mental math skills.

This class, which is designed for advanced 4th and 5th-graders, is open to the graduates of Junior Circle 1 as well as new students (as determined by testing). The curriculum builds on the concepts introduced in Junior Circle 1 and the goals are to continue to learn creative step-by-step problem analysis and practice thinking about problems logically from multiple perspectives.

The topics and problem-solving techniques include logic, parity, word problems, constructive problems, elements of the graph theory, elements of combinatorics, number puzzles. Practicing mental math methods, and engaging in friendly math competitions is an essential part of the class.

This is a challenging class for advanced students who are ready for pre-algebra course and who enjoy working on challenging math problems. The “hands-on” element of the curriculum is balanced with more challenging material required for building a solid foundation for our middle school program. The students will be learning about arithmetic and algebraic methods for word problems, prime factorization and divisibility, about fake coins and weighings problems, geometry and much more. This is an intensive class that includes material useful for math competitions.

This class is for motivated students who enjoy problem solving and mathematical challenges.

During the year, we will take a deep dive into many cool topics of extracurricular mathematics. We will also be working on skills that help students to do well at middle-school competitions, such as AMC8 and Mathcounts. Some of our favorite topics for this age include the logic of Knights and Liars, proofs and plausible reasoning, number theory, binary numbers, the structure of numbers, cryptography, games and strategies, invariants. We will also be practicing word problems, combinatorics, probability, etc.

The emphasis will be on mastering methods and techniques as well as on thinking and reasoning behind the methods. There will also be plenty of math fun: puzzles and AHA! problems, mathematical games, and Olympiads.

Admission is selective: by the results of the placement test, by a teacher recommendation, or by a qualifying score from a relevant math contest.

This circle is for the students of grades 7-8 who have already attended a math circle, or are familiar with our Intermediate Circle 1 topics, or are ready to put in extra work to catch up with our Intermediate Circle 1 program. We'll be expanding our understanding of previous topics, and we will be introducing a wide variety of new topics and problem-solving techniques. We'll be learning proofs by contradiction, necessity and sufficiency, and other proof concepts. The students will get acquainted with elements of divisibility theory, graph theory, invariants, colorings, geometry, strategic games, and number systems.

Languages are fascinating. They emerge seemingly on their own. No single person seems to invent their grammar, yet they exhibit a rigorous structure and well-defined rules. Join us to discuss language-related topics and solve problems from NACLO (North American Computational Linguistics Olympiad) and other computational linguistics contests.

We will talk about the origin of language, their history, how languages change, and methods for studying languages of the past. We'll explore different language types, their grammar, relationships, and the diverse language families found on Earth today. Join us to discover how linguistics unites a love for languages with the analytical and technical skills of STEM.

Ever wondered what kind of mathematics do programmers need? How much do you know about modern-day cryptography? What is a search algorithm on a graph? How are binary and hex numbers related?

Modern computer science is largely built on a branch of mathematics called discrete mathematics, which is the study of discrete structures. Logical statements, networks, and integer numbers serve as examples of such structures.

The course focuses on selected topics in discrete mathematics, their applications in computer science, and on problems that require reasoning and proofs. The students will learn about Boolean logic and logic gates, number theory and cryptography, networks and graphs, algorithms on graphs, number systems, proofing techniques like induction, recursion, invariants, and more.

This course systematizes essential pre-Algebra knowledge and skills and essential topics in Algebra, Geometry, number theory, combinatorics and probability. The class emphasizes understanding and efficient problem-solving techniques. It is suitable for students who are ready for a school Algebra 1 course, and covers many of the same topics.

The course gives students the skills and knowledge required to solve a broad range of problems essential to the mastery of a middle school math curriculum and which the students can encounter among the first 20 problems of the AMC8 (American Mathematics Competition) test.

The instructions are fast-paced. The class is suitable for students who do well in their school math course and would like to excel in problem solving, learn new advanced mathematical topics or participate in math competitions. Placement test is required.

The goals of this advanced program are to set a solid foundation for high school math courses and prepare for math competitions like AMC8/10, MATHCOUNTS, WSMC. We start this class from an extensive review and study to prepare students for AMC8. Next, we go deep into important topics from algebra, geometry, counting and probability, and number theory. The scope of this class roughly coincides with the range of topics covered on AMC8. It is suitable for students who are already familiar with an Algebra course. Could be taken together with Geometry for grades 6-8.

These programs invite young chess players who already have a complete understanding of the rules and some playing experience to come and develop their skills. Each lesson is organized as a combination of a short lecture accompanied by a set of analyze-and-solve-together exercises and followed by practice games in the second part.

Level 1: Students will practice important tactical patterns, mating techniques and pawn endings, learn basic opening ideas, and deepen their overall understanding of the game.

Level 2: On this level students will get familiar with more advanced tactical themes and patterns, further deepen their knowledge of different types of endgames, learn some opening theory and important pawn structures. Recommended as a continuation of the level 1 program and also open to new students.

The teacher's approach is to foster love and appreciation for chess as an exciting, logical game while using it as a tool to develop strategic thinking and problem-solving skills.

Coach Andrey Yatsenko is a long-time math teacher and an experienced chess player.
