I love this tutoring service. It's affordable and everyone is friendly, my child has completely changed as a student, going from crying every time she did math, to working on her homework independently and quickly. I'm so thankful to have found this service

I’d love to have bi weekly updates on what she’s working, if she’s treading in the right direction or at least moving the needle. I know weekly updates could be too much but she’s very vague on what’s SHES working on etc….

My daughter has done very well this year in her advanced 7th grade math class. Her mathnasium sessions were very helpful to her in gaining better understanding of the material presented in class. She found it enjoyable in a low stress environment.

My 12 year old daughter needed to build confidence in her mathematics skills. She engaged in on-line tutoring sessions twice a week and it has made all the difference. She is much more confident and her grades have improved.

Our daughter continues to perform at the “A” level in her math course which is an advanced level math. Mathnasium is very flexible in scheduling our daughter with tutors that work effectively to get her to perform at this level. We look forward to the time when we can return to in person sessions.

We were referred to Mathasium by another classmates parents and have been very pleased with our daughters progress thus far. The one-on-one interaction has allowed our daughter to be very focused and it seems to be the 'click' she needed since this is her weakest subject. The reporting with detailed communication from the teachers is also a plus. Strongly recommended by this family!

Very knowledgeable tutors. My student was actually understanding Geometry!

When other parents ask me about mathnasium the conversation usually wanders around to the cost. I tell them that you can’t put a price on increased confidence and performance that comes with structured tutoring. The decreased stress at home when it comes to homework time and studying for upcoming exams is also a bonus! This is a no brainer for this family and the cost is well worth it!

Our first experience with tutoring... calculus. I expected that only lower level math tutoring was available. I was wrong! Our high school student, who was embarrassed to seek help, enjoys her sessions and says that the guidance given is very helpful. Mathnasium saved me from a few more gray hairs. Price is reasonable and scheduling has worked out well.

Mathnasium in Portsmouth RI is just wonderful! Doug and the staff are so helpful and encouraging. My son has gone from a C math student to an A math student! At the recent parent-teacher conference, his math tutor told me he was a leader and actually assisting other students in the class. I can’t thank Mathnasium enough!!

Mathnasium helps Sophia feel more confident. I think she has learned some math concepts that she didn't know before. Math does not come easy to her but your excellent staff helps her 'swim' through it rather than 'go under.' Many thanks.

Exactly what my son needed; in-depth teaching and understanding of math curriculum, homework help and a confidence boost! In addition, my son loves the teachers, games they play during breaks, rewears system and looks forward to going to each season. My husband and I highly recommend Mathnasium and the owner, Doug!

The staff and program at Mathnasium are wonderful. Our son went from having no confidence in his ability to do math, and failing his class, to making the honor roll after a short time in this program. Not only did he get his confidence back, he also understood the math concepts and processes. The program at Mathnasium helped along with the patience, guidance, and encouragement from the staff members. Thank you Doug and staff!

Your technique works! In less than 2 months my grandaughters' math confidence has skyrocketed. Her math scores have improved, and her teacher has complimented her work with positive comments. What a boost to go from struggling in math to being able to complete her math worksheets almost all the time. Thanks to the team for helping Sophia catch up with her class and move forward.

My high school sophomore has been a student at Mathnasium Portsmouth since July 2018. We could not be more pleased with their amazing program. Doug Stearns and his exceptional tutorial staff create a warm, welcoming, friendly environment for learning. My daughter always looks forward to her sessions and has learned far more from this program than from any private tutor that we have had in the past. For a student with learning struggles, math can be very intimidating. The tutors at Mathnasium are consistently insightful and encouraging, unwaveringly patient, and sensitive to student struggles. They know how to empower students. They build not only their students' mathematical abilities but also their confidence. I only wish that I knew about this wonderful program years ago.

John Abell
Mathnasium has been invaluable to us both in content and flexibility. Passing of higher level math courses would not have been possible for this foreign student transitioning to a new life in the United States. Because he really enjoys competitive sports, the willingness of the program to adjust to practice and games was very appreciated.

My 10 year old daughter loves to go she has improved greatly especially in her confidence. My 15 year old son that is very good in math went over the summer to prepare for 10th grade and he also didn’t mind going and it was a great introduction to the advance geometry he is now doing.

Mathnasium and Doug were absolutely wonderful. My daughter went there for her
senior year of high school and her grades were always in 90s. i would definitely
tell parents/students who are having math issues to contact Mathnasium and give it
a shot. You will see the grades rise and the students be happy as they have
the math explained to them one on one.

Our son was struggling in his math class and in that same year he brought his grade up by 2 full marks and scored a B on his exam. He never fought going to his Mathnasium class and always kept a great attitude getting through it. The tutors at Mathnasium did right by him on multiple levels - I highly recommend Doug and his team. Thank you so much!

Our son went up 120 pts on his first SAT vs. his math score the year prior on his PSAT. We’re thrilled. The location is convenient and their system is cost and time efficient and gets concrete resuts. We will be back for some refresher sessions before he takes the SAT next fall.

My boys love going to Mathnasium. We use it primarily as an "enrichment" experience. Doug and his team make Math fun and exciting and my 10 and 12 year old look forward to it every week. I feel we get very personalized attention and feedback - which makes me feel part of the "family". I would highly recommend this!

Located at 14 Potomac Road in Portsmouth RI, Mathnasium provides tutoring for students in grades ...
Hello. I'm Ryan Costa, Owner / Center Director of Mathnasium of Portsmouth, your neighborhood math-only learning center. We help kids in grades 2-12 understand math by teaching the way that makes sense to them.
When math makes sense, kids leap way ahead – whether they started out far behind or already ahead in math. Our formula for teaching kids math, the Mathnasium Method™ has transformed the way kids learn math for over a decade across 1,000+ centers in the US and Canada:
Our specially trained math instructors will teach your child how to understand math in an individual setting – our unique approach enables us to effectively explain math concepts and lend a helping hand to every student. Our tutors foster a caring, encouraging environment that helps kids thrive and learn!
Mathnasium instructors use our unique assessment process to determine (with great accuracy) exactly what each child knows and what they need to learn. Next, we design a customized learning plan for teaching the concepts the student needs to master. It doesn’t stop there – our encouraging instructors continually check progress along the way to make sure kids truly understand and retain the concepts we’ve taught. The results are transformative – kids will see measurable changes in attitude, confidence, and school progress.
Our instructors will also set aside time to provide homework help. We help kids understand the homework assignment so they feel better prepared to complete the work at home – underscoring their understanding of concepts and transforming homework frustration into a welcome challenge.
