RSM Acton

RSM Acton RSM-Acton is a branch of the Russian School of Mathematics, an award winning, after-school math program for K-12 students.

Since 1997, RSM has helped children develop math fluency, intellect, and character, empowering them for life. One of the first branches of the Russian School of Mathematics in Greater Boston, RSM-Acton provides a top-quality world-class math education for students grades K-12 with an emphasis on problem solving and critical thinking skills. In addition, we offer other enreachment programs such as SAT-I English & Math Prep and college-credited courses such as AP Calculus (AB & BC) and AP Physics (I & II). Since our school first opened its doors in the Fall of 2008 (in the basement of our house), we have experienced phenomenal growth. Over 1000 students attend RSM-Acton every week, and almost 100% heard of us through “word of mouth” from our satisfied customers. We are conveniently located at the heart of Acton on Main Street (Route 27N), between the Acton Memorial Library and the Central Post Office, and easily accessible from Routes 2, 27, 111, and 495.

When your child faces a challenge, will they give up or say, “Let me think”?
At RSM, students learn to stay curious when answers don’t come easily. They question, explore different approaches, learn from mistakes, and keep going.
Because the goal isn’t simply to find the answer, it’s to develop the confidence and skills to think when the answer isn’t obvious.
Welcome back to a new school year of challenging minds and growing thinkers. 📚

Aariv has been part of the RSM Acton community for 7 years. His parents have played an important role in his success, helping him understand key concepts, answer questions, and work through challenging problems as he prepared for competitions such as AMC 8 and Math Kangaroo.

When asked what advice he would give other students hoping to excel in math competitions, Aariv emphasized understanding formulas, reading problems carefully, practicing regularly, and taking practice tests.

💡 Aariv’s advice:
“The more you practice, the more confident you will feel on test day.”

Aariv, we are proud of your dedication and hard work and wish you continued success in all your future math competitions!

Where can a strong foundation in mathematics take you?

For RSM alumnus Preston O’Connor, it has led to an exciting path in computer science, mathematics, machine learning, quantitative finance, and cybersecurity.

Preston first joined RSM in elementary school, when fractions were a challenge and mathematics was not yet a subject he enjoyed. What began as an extra math program quickly became something much more meaningful. With supportive teachers, challenging problems, and a classroom environment where students were encouraged to ask questions and learn from mistakes, Preston developed a completely new relationship with mathematics.

Today, he is pursuing dual bachelor’s degrees in Computer Science and Mathematics at UMass Amherst through the Commonwealth Honors College, along with studies in Applied Mathematics, Statistics, and Data Science. He plans to continue into UMass Amherst’s accelerated master’s program in Computer Science, specializing in Machine Learning and Data Science.

His experience extends well beyond the classroom. Preston has been involved in AI research, cybersecurity, software engineering, and quantitative finance, and is currently interning at Walleye Capital, a multi-strategy hedge fund focused on quantitative finance and artificial intelligence.

Preston credits RSM with giving him more than a strong mathematical foundation. It taught him how to think through difficult problems, persevere when the answer is not immediately clear, and truly understand concepts rather than simply memorize them.

Those skills have continued to make an impact throughout his college career. In fact, an unexpected connection to RSM even helped Preston become involved with UMass Amherst’s cybersecurity team. Several team members were RSM alumni themselves, creating an instant connection that helped open the door to a new opportunity. Preston eventually became one of the team’s officers and helped the team maintain its #3 global ranking.

And the advice he gives students today is advice he continues to live by:

Never compare yourself to anyone else in your class. Compare yourself to who you were yesterday.

Whether the progress is from a D to a C or from solving one difficult problem to the next, progress is something to be proud of. Everyone learns at a different pace, and the goal should be understanding, not simply being the fastest person in the room.

It is especially meaningful that Preston now shares this same advice with the college students he teaches as a TA.

From struggling with fractions in elementary school to working with machine learning, quantitative finance, and cybersecurity, Preston’s journey is a powerful reminder that where you start does not determine where you will go.

We are incredibly proud of Preston and grateful that he continues to be part of the RSM community.

First grade is a big year for little thinkers.

Back in the classroom, our first graders are doing something much bigger than learning to calculate; they’re learning how to think mathematically. 🧠✨

And these aren’t even our youngest students! At RSM, children begin developing mathematical thinking from an early age, building the foundation for deeper reasoning and problem-solving.

Our first graders explore patterns, relationships, logic, and challenging problems that stretch their thinking. They ask “Why?”, try different approaches, and discover that there can be more than one path to a solution.

We can’t wait to see where their curiosity takes them this year! ❤️

We’re excited to spotlight Tara Stevens, an RSM alumna who has taken the skills she developed at RSM with her on her journey to Colby College! 💙

Tara shared that RSM helped her strengthen her overall math knowledge and prepare for SAT-style questions, giving her greater confidence in math along the way.

But some of her favorite memories from RSM go beyond the classroom. Tara says she especially loved the camaraderie she built with her classmates, a reminder that the RSM experience is about both learning and the community we build together.

✨ Tara’s advice to today’s RSM students:

“Keep studying and working hard. Do well on the SAT, get a good GPA, and do high-impact internships in college. You should be fine as long as you grind.”

We’re so proud of Tara and all that she has accomplished! 🌟

If a student isn't passionate about a math-centric career, what is the benefit of after-school math classes?
We've received this question numerous times over the years, as the concept of extra math classes or an after school math program can be surprising to some. We're here to share 3 reasons why we believe math truly matters.
