Mathnasium has been great. My 12 year old daughter who was once “math-fearing” now excels at the subject. The staff is friendly and knowledgeable. The director, Debbie, is amazing; also, she is so accommodating!

My son loves this place, the team is great and coach really well. Debbie is a great mentor and is very passionate about running this institution so well. They do frequent assessment and keep refreshing the curriculum for the kid accordingly. My son even wasnt even interested in any other classes during the weekdays as he wanted to be in Mathnasium 5 days a week. He was in 4th grade and was still doing 7th grade Math. Math never was stressful for him.Highly recommend this place.

My son was struggling with his college algebra class. My friend told us about Mathnasium and I enrolled my son immediately. He started to get a handle on the information immediately and came home saying how wonderful it is to have someone who KNOWS and understands math explain it to him in a way he could understand. I have nothing but good things to say, and should he need more help, this is where we will be going!

Mathnasium in Denville is a wonderful place that has helped my kids accelerate in Math. Ms. Debbie Lum and her team are very knowledgeable about the curriculum in the schools and are very flexible with how the sessions are run. We use Mathnasium as a supplemental tool to keep their math skills above average. Although we find Mathnasium's curriculum to be excellent, on occasion, we have asked the teacher to assist with homework or review for a test, which has been very helpful. I HIGHLY recommend for all ages and for all levels of math!!! - H [LAST NAME REMOVED]

My son had a tough time with virtual learning. Mathnasium was filled with kids his own age who had similar difficulties with remote learning. Mathnasium helped him fill those gaps and gave him confidence. I would recommend it without reservation!

Mathnasium of Denville us filled with great instructors who care about the kids. The management team is fantastic and go above and beyond for individual support and attention to both the students and parents. I am honored to give them my highest recommendation!

Ann Marie O'Keefe
Mathnasium has been a blessing to assist my boys with Math Tudor help. They have been in the Denville Mathnasium program for three years now. They previously went to a one on one Math Tudor. While this was helpful it did not accomplish what Mathnasium has mastered in creating an individual assessment and learning program to focus on their needs. I highly recommend this program as it has changed my boys attitude and ability to take initiative on their own to complete homework and increased confidence in test taking!

The staff are flexible and accomodating for our busy schedule. They have improved my son's math skills as well as his grades. He has become very independent of needing any assistance with the skills that he has learned at Mathnasium. I would strongly recommend them to anyone whose child needs a better understanding of math skills.

Matthew's math skills have increased significantly since taking classes with Mathnasium. He can be quite a challenge when it comes to dedicating time for his schoolwork. But his experience with Mathnasium has helped quite a bit. We would highly recommend Mathnasium to other students.

Denville Mathnasium has done an excellent job of continuing to provide the same level of interaction, challenge and service on-line as it did in-person.

Cindy Robbins
Grateful that we had Mathnasium in place when the whole world shut down. The way they were able to transition the entire operation to an online platform almost overnight provided our daughter with a consistent, familiar routine in middle of a pandemic. She was able to continue with her specialized learning plan. She was able to see and interact with her instructors. The instructors all know her and get her, they know how to break things down for her so she “gets it.” She could never get this personal level of instruction in school. She actually likes math now.

During this unprecedented time, I take my hat off to Mathnasium. They persevered and managed to get it right. The online process for my daughter continuing to receive the great experience and helpfulness they offer all in the safety of her home, has been nothing but exceptional. I truly appreciate how Mathnasium has been willing to work with us during a time of uncertainty and keeping my daughter on a schedule she was used to.

The Denville Mathnasium is different from many math centers in that the owner is part of the classroom. She doesn't just sit in the office but also teaches the kids. What I like the best is that the staff there tries to understand the children's personalities in order to take the best approach in teaching them. My kids have been going there for years and don't complain about having to "learn" math...it actually is a fun activity for them.

The Center Director is always looking out for the overall development of all the students. The encouragement that the students get from the environment of Mathnasium of Denville is unparalleled.

Mathnasium has given my daughter some confidence in math which she lacked completely before we started coming here. She raises her hand to answer questions in math class frequently now. She usually gets one on one attention here depending on the time of day we arrive, which makes the monthly cost great value when we go more often. She has found the tutors to be very friendly, kind, intelligent and great at explaining math topics.

Hello. I'm Debbie Lum, Center Director of Mathnasium of Denville, your neighborhood math-only learning center. We help kids in grades K-12 & Adults 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.
