Our Results

At Mathnasium, we help kids understand math by teaching the way that makes sense to them. Children who consistently attend sessions at our learning centers enjoy a transformative learning experience and make huge strides in the classroom.

Attitude: When math makes sense, kids develop a more positive attitude toward math.

Understanding: Mathnasium teaches for understanding, giving students the ability to succeed in any math environment. As Larry Martinek, Mathnasium’s Chief Instructional Officer notes, “It's pretty easy to forget things you memorize and near impossible to forget things you understand."

School Progress: When kids learn math in a way that they truly understand, they achieve greater success in the classroom.

My kids do not like doing academic work, but somehow they enjoy going to Mathnasium. Both have told me they have an easier time following along in Math class in school, and they are doing well. I think the instructors are passionate about Math and capable of teaching in a way that makes sense to kids-- a winning combination. Couldn't be happier.

A great, professionally run program. Our daughter actually looks forward to math!

Mathnasium offers a few different programs to help your child in math.  Click the program below to learn more about how we can help your child.


Struggling with Math? Mathnasium can help your child get caught back up.

Is your child gifted and talented in math? Need an enrichment program to help your child stay ahead in math? We can push them to excellence in math



Both my children loved the warm, professional environment with little distraction and lots of attention. Without a doubt, it boosted both their confidence and their interest in math. We were so impressed with the level of communication and personal interest that Mathnasium brought to the table. Two thumbs up.

My son is not a fan of math but mathnasium is the one place associated with the subject that he enjoys attending. The staff is attentive and patient, they work at his pace while keeping him engaged enough to want to do more. The past year has been a positive learning experience for my son and I'd recommend the program to anyone.

My daughter has a confidence and joy for math she never had before. Her teachers have noticed it, too. It takes away the fear and anxiety, and gave my daughter a way to get excited about math. 

My son, Nick attends Mathnasium weekly and has improved greatly. He looks forward to going each week and working with such excellent teachers. Thanks to all the amazing staff working there, my son has reached all his goals this year. You all do your best to accommodate us! We ❤️ Mathnasium!

From a parent perspective the center is extremely organized, which makes it easy and a pleasure to deal with. Carl is responsive, knowledgeable, attentive and helpful. I've also had positive experiences with staff members I've interacted with at the center. Most importantly my kids, who have always claimed to dislike Math, enjoy going. They have a good time, but I can tell that they are actually stretching their brains and learning. The approach is perfect for my kids, and progress evident. So far so good, thank you!

We are so happy with our children's progress at Mathnasium. We've been going since spring 2017. I wish we had known about Mathnasium sooner. If we had known, we would've started our membership beginning when my first child was in kindergarten. We love it!

My daughter was failing math miserably two years ago. She had lost all confidence in her ability to understand and do math. Since she began attending Mathnasium summer of 2016 she has made tremendous improvement. She passed the NYS math exam in 8th grade and she passed first semester algebra 1 in high school and just started her first day of algebra 2 yesterday. Mathnasium is a great resource for my daughter and continues to be. It’s the best choice we made for her!

Our daughter really enjoys going to Mathnasium. It is a supportive environment to learn in and has made her so confident in Math at school that she is now a leader in her classroom and a "math helper" to other students. She truly enjoys doing math and is proud of herself when she comes home from Mathnasium with what she has accomplished. For our daughter, Mathnasium has been a positive, confidence building experience overall.

We're so happy we decided to enroll our son! Everyone at Mathnasium Boerum Hill is incredibly caring and it shows in their results. In just 6 months, our son went from crying in frustration over his math homework, to confidently doing it by himself without any help from Mom or Dad! On his first 4th Grade report card, he received his first "4" in Math; the highest grade possible. He still may not necessarily enjoy his math homework, but he definitely has the skills to get through it with ease. Thank you!!

Our daughter LOVES coming to Mathnasium. She asked us to sign her up at the beginning of the school year and is still going every Saturday with a big smile on her face. She enjoys the curriculum and the chance to "get ahead" on her math skills. Thanks everyone!! 

My son first started Mathnasium in 6th grade, with the support he received here he was able to increase his grade from a 2.8 to a 3.5 in less than 9 months. He has a better understanding of those fundamental concepts and is now set to complete his algebra regents in 8th grade. Thank you Mathnasium for your support.

Carl and his staff are phenomenal. All three of my kids have participated over the years and come out way ahead of grade level and super confident in math. I am a major proselytizer!

My son loves his time spent at Mathnasium. Even Saturday mornings he is happy to go and comes out smiling. For a 13 year old who loves to lounge around on the Xbox or go to the skate park, this is a big deal. He has a variety of teachers that he works with and he likes them all. He takes pride in "being a Math guy" and this is vital for a kid who is not in traditional sports. He talks about moving through the books and advancing into new chapters with pride. We started Mathnasium to secure a spot in 7th grade Algebra. He not only tested into this class but is doing well. First semester grade was 102. I suggested stopping for a while but no. He wants to continue to advance ahead to prepare for 8th grade Geometry. 

Our children have had a positive experience with the mathnasium program and the supportive and friendly staff and instructors! I appreciate how they focus on the individual needs of every student to strengthen the areas that need help and bring confidence with every achievement in their sessions and in school.

Our family is so happy to be a part of the team. It truly feels like everyone at Mathnasium is in it for the right reasons and we’re all working together to help make math less of a chore and more of an accomplishment for the kids.

Mathnasium has been a blessing to not only our daughter but to our family. Doing math was always a challenge that never ended well. My daughter was discouraged and we were frustrated. However, since Mathnasium we've seen a boost in our daughter's confidence. I know it sounds cliche but honestly she is understanding the material, participating in class and she is passing math in her first year of high school when in middle school her teachers said she would never be able to fully understand math. Our daughter is not an "A" student in math yet but, she went from failing every test in middle school for years to an 83 average in math now.

Great customer service!!! Carl calls the parent personally and respond to all concerns/questions. He is very patient with his responses and shows that cares while working with you. I have 2 of my children enrolled in Mathnasium. At first my children hated math and were scared of it. Mathnasium helped them overcome their fear of math and is working on bringing them to their grade level. I had to drag my children to any math tutoring session. Now, they are the ones reminding me of their tutoring sessions. They love the place and feel connected with the staff. I am very happy with Mathnasium and its entire staff. 

My son has been going to Mathnasium for about a year now. He’s progressed nicely And has gained confidence. The instructors are friendly and really know how to work with kids. They are approachable and focused on each child’s individual needs.

Mathnasium is a nurturing environment where independent thinking and personal growth go hand in hand with math learning. Students at Mathnasium are listened to and all teachers are well prepared and reachable. They help the students build not only content knowledge, but also confidence.

My daughter's grades and math understanding improved greatly while in Mathnasium. The staff is wonderful and accommodating. I was always kept updated on her progress and any concerns I had were addressed promptly and in a satisfactory manner. The program is flexible and I was always able to switch times or reschedule appointment with zero hassle.

Great, attentive and communicative staff. The team is a well-oil machine, and gives each child special attention. I also really appreciate how open and honest feedback about my child and different learning environments are. Often I had questions and the team was always very responsive in a timely manner. Most importantly my daughter learned to love math again, actually begged to not miss game night and even asked to double her time at Mathnasium. That is statement enough I think. :)

Mathnasium is the best!!! My son Jeremiah has become more confident with math skills, he loves coming here every week! Also he got an Math award at school for highest math grade!! I'm thankful for this program! 

My daughters went into this program very apprehensively(as they do with any academic related work) and they left with a much more positive attitude about math! One of my daughters who has been struggling with math and scoring low on her tests came back this week with a smile as she scored the highest she has this year! It has built her confidence and I look forward to seeing her growth in math!

My daughter who "hates math" loves coming to Mathnasium and has asked if she can come more than twice a week! Her math grades have improved dramatically, as well as her confidence as a student.

My daughter loves going to Mathnasium, always comes out with a huge smile and is eager to tell me all the stuff she figured out and how. It's wonderful to see this after her reluctance and discomfort with math previously. She's always excited about math days!

Mathnasium helped build my child's confidence. We also saw a significant change in terms of her attitude towards, and performance in math class.

My daughter loves going to Mathnasium! Her math has improved so much and with it, her confidence. She has already asked if she can go again next year. We are thrilled that she enjoys it so much.

Mathnasium has done nothing but help my 2 sons with their math issues. Carl is quick to respond to emails, and is patient with the ever-changing schedule of busy kids. As a worried parent, Carl and his team find solutions to support my kids' weak areas. Within 2 sessions at Mathnasium, my son has a clear understanding of a particular type of problem. My teenage son likes to use Mathnasium during the summer months, to keep math concepts fresh in his mind for the Fall. I have recommended Mathnasium to many friends and will continue to do so.

I just wanted to let you know that Cameron got an 800 on his Math SAT! We are very proud of him and we wanted to thank everyone at Mathnasium who have worked with him over the years. You guys definitely have cemented a solid math foundation for him.  

In a very short time Mathnasium was able to turn my daughter's negative attitude about math being "not her thing" into a much more positive attitude. She no longer thinks that she is not good at math, which at age 10, seems to be most of the battle. We plan to stick with Mathnasium through middle school - looking towards those critical high school applications!

I am very happy with my daughter's  experience at Mathnasium. She still enjoys Mathnasium after attending regularly for two years which is excellent. Mathnasium has been a valuable source of math enrichment, reinforcing the math my daughter learns in school.

We love Mathnasium! Our daughter's confidence in her math ability has grown stronger over the past year. We, as parents, were at a lost because the new methods of teaching math seemed so confusing to us. We need help! Mathnasium was the answer for us. We highly recommend it.

A great alternative to private tutoring: experienced tutors, clear goals, assessments, well-designed curriculum. We've seen marked improvement in both kids and, most importantly, they are no longer afraid of math! Good stuff.

What great teachers and staff!! You are all so amazing to all the students! Thank you for helping and being an inspiration to our son! We ❤️  Mathnasium.

My daughter gained much needed confidence with her math this year and I'm sure she will be returning. We feel it's well worth the money.

My daughter loves coming here. Friendly and caring staff. They make learning fun.

You guys are great communicators and teachers, and most importantly, my son loves Mathnasium! It's built his math confidence and he really enjoys going.

I like mathnasium because they are personable and flexible. It is easy for my daughter to get to and I see the improvement in her confidence and her grades.

Carl, Laura and the whole staff have been flexible and helpful with our daughter. She is more confident and doing well in her math class. Thank you!

My daughter has really enjoyed her math practice so far and the way everyone is friendly and helpful. She thinks the binders are cool and likes the way things are organized.

Our daughter has been going for two years and has grown to love math! The program has given her confidence and to push herself harder. I would recommend this program (and do) to anyone looking for math help. Carl and his team are fun and friendly while pushing the kids hard.

I would definitely recommend your services to someone in need of support. My child has found her confidence in learning math. She is no longer fearful of tackling a math problem!

When I first stepped into Mathnasium I didn't know what to expect. All I wanted is for my son to step up his math skills and get better grades - everyone at Mathnasium is great! My son loves to work with any of the instructors. Now his confidence has gone through the roof! He's doing better at school and gets great grades in his math exams. I’m so thrilled with the one and one experience he gets when he goes there! Now he is doing seventh grade math even though he's a sixth grade student - thanks to all at Mathnasium he's a math genius in the making! He never complains when I say it's time to go to Mathnasium, he's always running to his math class - now that's something special!

My daughter has always has always done very well in math. AP Calc was a challenge. Mathnasium gave her the extra help she needed . The instructors were very helpful and she enjoyed going.

Carl & team have completely transformed my daughter's math experience around - she started at the bottom of the class in math and now her teachers are saying that she is at the top and helping others. Pretty incredible how rapid and significant the change has been.

Since my daughter started Mathnasium her math skills have improved 10 fold! She also enjoys math now! She's also ahead of the curve in her class at school.

My daughter LOVES coming to her sessions at Mathnasium - and she previously "HATED" math! Her confidence in her ability has improved as well her math grades in just a few months!

Mathnasium is a clean and well organized center. The staff is friendly, helpful and professional. Generally very accommodating with schedule conflicts and responsive with inquiries via email. My daughter enjoys going and finds it helpful with her math advancement. I find their Progress Report simple yet informative. Would definitely recommend friends.

Everyone is pleasant and knowledgeable. I greatly appreciate the comfort level my daughter has as a result of caring tutors.

The positive influence was noticeable immediately. My child's level of stress decreased and level of confidence increases after only a couple of sessions.

I am so glad we chose to send our daughter to Mathnasium. Before she began at Mathnasium, she was behind in her math class at school; she was not understanding concepts, which was leading her to receive poor grades. Now, she actually enjoys attending her Mathnasium sessions because she knows how much it Is helping her- she wants to do well in school! I also love that her instructor helps her to complete her homework for the day each session that she attends. This helps us both!

My daughter absolutely loves Mathnasium - we actually go for two reason - additional assistance for school since we don't like her schools math curriculum and for pure enjoyment!

Mathnasium works! My son was failing math -- an actual F. He now has a B, and growing confidence in his math skills.

I am pleased with my daughter's excitement about math. It has become a hobby to her.

Mathnasium has been consistent at enabling our daughter to cope with constantly changing curriculum and increased pace. We remain grateful to Mathnasium for her success in high school math.

My daughter's grades immediately improved after she started coming to mathnasium. She also really likes. She is always smiling and in a great mood when I pick her up!

Our son truly enjoys going to Mathnasium for his math "play dates!" The instructors are warm and patient and they make learning new concepts and exciting challenge. All in all it has a been a wonderful experience for our child.

Great program! The way the schools are teaching math is so very different from the way I learned it. Mathnasium is good with navigating this new system. The "team" is responsive to my last minute suggestions on areas to focus on even when it deviates from their program. I know that I must supplement my child's math education, Mathnasium made it easy to do!

My son is very comfortable with his tutor. It is too early to determine if he has gained more knowledge of the subject matter, but judging by my son's demeanor, he seems to have a new found confidence.

Carl is very responsive and willing to accommodate our schedule. We feel very good here.

We have been clients since the opening of Brooklyn office and can't thank the team enough. My children do not have problems with math, i mean they do make errors and get wrong answers, but they are not afraid of the subject and they have many technics and strategies helping them to tackle tests and quizzes. Not only i do not have time to practice with kids at home, as they grow older i am increasingly unable to help them with all of new algebra and trigonometry they have coming to them. Thank you Mathnasium for great work, care, patience, and kindness you put into educating my children!

My son loves studying with the teachers at Mathnasium, and he enjoys the atmosphere there (and the prizes). He also loved the game night & wants to come to another one. The pro-math learning environment is terrific!

My daughter was reluctant to do any math or even go to Mathnasium. In the past 3 1/2 months she has attended Mathnasium she has gained confidence and has shown improvement in math. She has become more independent when doing her math homework. I am happy to say that she has passed her first math quiz of the school year!!!I attribute this to Mathnasium's methods and strategies and devoted staff.

My son loves Mathnasium! He looks forward to going to his tutoring hours after school. He was moved to the accelerated math class in his middle school this year. I think this was due to the time he spent at Mathnasium in his 6th grade Spring. We told a friend of ours about Mathnasium and she has her son going now.

My daughter actually likes Math but was always frustrated because no one has ever taught her less complicated ways to solve math problems. However, after the first session at Mathnasium, she said to me, "this is what Miss D.... Was trying to teach me all this time." She loves Mathnasium and the way they make math make sense.

I was recommended to Mathnasium by a friend and I enrolled my son in November and before the end of the school year we saw great results. He learned great skills that he was able to direct to his other subjects. Not only did he go from a C- student to a solid B+ student in math but his overall average improved. We are so very pleased with Mathnasium. It was worth the time and money. I will be enrolling him this school year. He will be entering the eighth grade. Many of his frustrations with math has gone away and that's comforting for me as a parent.

My kids love it! Teachers are very sweet and while they are learning math they are also learning to like math and my son now knows a magic trick! Great place...thank you.

Really pleased with Mathnasium. We've been coming for over a year now and feel its been extremely effective for reinforcement as well as test prep.

Before my son started Mathmasium, he really struggled in mathematics. He had little to no confidence in math and just was completely turned off with the subject. Since being a part of Mathnasium, he has improved and his confidence level is soaring.

We highly value the additional focus on math that our daughters are receiving. As a result, math has become one of their favorite subjects at school and significantly promoted their confidence in the subject.

The insights and observations Carl provided at the outset, from the initial assessment, provided an extremely helpful (and encouraging picture) on what areas to improve or enrich.

The entire staff under Carl's leadership is committed to building intelligent independently minded academic kids. They all care about what they do and it shows. Especially Karen. Thanks.

Our son's grades improved dramatically as a direct result of his attendance at Mathnasium!

My daughter feels much more confident when doing math and is no longer afraid to tackle challenging math problems. Thanks Mathnasium, you have changed her experience of learning. Now she can identify tools and methods that will help her to learn.

Very nice staff! Really helped my son in geometry!

My daughter feels that she has learned a great deal since starting the program. She is more confident when approaching math problems and is also positive about future achievements.

It helped my girls master the areas they were having trouble with, and it also helped them love math again! They really looked forward to coming, even though their appointments were on Saturdays!

When he started at Mathnasium his attitude about Math was a bit negative since he didn't know much or was always making stupid mistakes. After only a few weeks, he looks forward to going to Mathnasium because he has a few friends who goes there and his attitude has changed quite significantly. He said its fun going to Mathnasium to learn math.

My son liked math to begin with.... But now he's loving it. Not just he's ahead of school work, he enjoys learning new way to solve a problem ... He looks forward to come to you. ( this one is big score!!) As for me, thank you very much to be flexible for his schedule and easy to contact you. I really appreciate it. Keep up the good work!!

Carl and Mathnasium have been the perfect match to support our daughter's math development. They have helped to broaden her understanding of all the essential tools needed to excel and move to higher levels. All this has given her the self confidence in knowing she can work through any math problems that she is asked to complete. Carl and Mathnasium also make sure that they working with the Math program at the school and with the Math teachers.

Last year, Mathnasium supplemented my daughter's instruction and she gained confidence and ability in the subject area in spite of receiving weak instruction in school. We were very grateful that Mathnasium helped her overcome what could have been a very difficult Geometry class. We're very happy with her grade of 97 in math last year as a high school freshman. She worked hard and Mathnasium helped her do well on the Regents as well.

We have had a great experience so far. She is more confident in her math and feels really good about herself whenever she leaves her sessions. We are also seeing a lot of progress in her understanding her coursework at school.

My daughter is so happy with the place. She is a homeschooler and has to get herself to Mathnasium twice a week without any prodding. Its a testament to how amazing it is that she refuses to miss a class.

The owner is friendly, approachable and accessible at all times. He cares about the kids and wants them to succeed. My daughter actually likes going to her Mathnasium class.

I just wanted to let you know that the same child that told me I was ruining her life, is now the one telling me she loves Mathnasium and wants to stay an extra half hour every time. She said she feels like she is re-learning things from last year and better understands everything

She received a 90 on her first math final!!  She is so excited, many did not do well, so she is relieved and proud (and so are we).  Thank you so much for all you do there, it has helped her become so much more confident in math!!

So in the last couple of weeks since Sadie started with Mathnasium I have heard her say the following: "It seems easier when they explain it. Math doesn't seem as challenging. I feel more confident." All good things!

Thanks Carl. What you all do for the children (not just mine) is exceptional. The staff is wonderful! They know how to connect with the kids and their passion for math is contagious. Just letting you know that she has maintained a 99% average in Math so far this year and it is her favorite subject!! Quite a change from last year. Her teachers tell me she is always prepared, enthusiastic, and s delight to have in class. She herself says that Math is now her favorite subject again. Who would have known? Just thought you would like to know. 

My kids (now 8 and 10) have been going to Mathnasium for over 2 years (since it opened) and we love it! Carl, the owner, gives us attentive and caring service and his tutors are engaging know how to bring out the best in children. Mathnasium has become a necessary component of keeping our children at and above grade level in math. It advances them in areas where they show strength and helps them catch up in any areas where they might be weak. I?ve seen their confidence in math soar and their performance in school improve considerably. I also love that the focus is exclusively math. It means that the staff is really expert at what they do and it reinforces the importance of math in the kids. I just wish there was a Mathnasium when I was in elementary school!

Her math teacher just called - she has turned her math grade around from a C- last semester to an A- this semester. We are busting out proud of her and all her hard work. Thanks for all that you and your team do for her.

We've been at Mathnasium in Brooklyn Heights since September and love it! The owner, Carl, is extremely dedicated to providing a quality math tutoring and supplemental learning in a positive, energetic, and confidence-boosting manner. It's wonderful to be at a place that just focuses on math and creates such a welcoming experience for kids. I just signed up another child in the program and look forward to seeing the same improvement and enthusiasm fostered in her. Kudos to Mathnasium for finally making math challenging AND fun!  

My kids enjoy going to Mathnasium on Atlantic Avenue. My son looks forward to it and my daughter is appreciating the extra confidence she has at school due the support she gets at Mathnasium. It is very well run, organized and fun. They get solid work done while there and are really understanding and mastering math skills. Carl has an attentive and thoughtful approach to the student's needs. I highly recommend this math center.

My 7 year old boys have been going to Mathnasium and it has been a WONDERFUL experience. They are more confident in their learning and testing skills and they have actually learned to ENJOY math. I give Mathnasium my highest recommendation.

My 13 year old son has been going to Mathnasium for about 6 months and he really enjoys it. To be honest I was a little skeptical at first, especially because they do not disclose much about their approach of teaching math. My son does not bring home any work he did at Mathnasium, and I was not sure what to think. But it has become apparent that they are doing something right. My son's test results improved, and he is now much more confident about math. Carl and his staff are good, dedicated people. It is highly recommended.

Both my 9 year old and 6 year old are benefiting immensely from Mathnasium. Carl and all of the very patient and capable tutors are true to the Mathnasium method of making math MAKE SENSE. Mathnasium is a wonderfu boon to the neighborhood as it serves both struggling students and those students who seek math enrichment.

My kid was really struggling. She was 2 years behind in a school system already a year behind. She had really poor self esteem because she could not do the math. Mathnasium opened in Boerum Hill in May. We started right away. By fall she had caught up an entire year. Now, winter, she is on grade level and VERY proud of herself for her math! She is not only good at it, she loves it! At first I dragged her in, now she begs to go. Mathnasium has been great for her both academically and personally. Carl is a great teacher and runs a tight ship. My daughter is really thriving. Thank you Carl and all of the teachers!!!
