My children still enjoy mathnasium after us being there multiple years. I read every note I receive from their instructor of that day and it helps me check in with my kids about their progress.
They have come far!

The best decision and investment made for our child with ADHD, she hated math and now she now likes math!!!. Before she was afraid of tests and was anxious when it came to math.
They have created a safe environment for her and she is now learning skills to be more confident with math and her grades at school are amazing! The most important thing for us is that she is understanding what she is doing.

Our son was struggling in math recently, so we had to find him some help. We came across Mathnasium online and wanted to check them out.
He has been enrolled for almost a month now and I can already see more confidence in him when he is doing his math homework, or when asked a question about math. He still has some ways to go, but we are very pleased with the progress he’s made so far!

We’ve seen tremendous progress in skill but the biggest progress has been in confidence and learning that math isn’t scary or to be avoided. We are so happy we enrolled.

Considering the fear my child had about attending tutoring sessions for math, I'm glad Mathnasium has helped him overcome his fear. He has positive feedback about his sessions and is gaining confidence.

Thank you! Please tell us more about your great experience with us.

We’ve been homeschooling our daughter for about six months and, despite our best efforts, we just weren’t seeing the progress we hoped for in math. We tried everything. Teaching her ourselves until the crack of dawn, YouTube videos, Khan Academy, Beast Academy, worksheets, and countless curricula, and it still just didn’t click.

Since adding Mathnasium, we are finally back on track. The difference has been incredible. Their structured approach, individualized support, and regular progress checks give me real confidence that my daughter is not only learning what she needs to but actually understanding it.

I also want to give a huge shout-out to Tony, Faith, and Naelly, along with the rest of the staff. They truly know how to meet my child where she’s at, build her confidence, and help things click in a way that feels encouraging and supportive.

What I appreciate most is being able to see her progress and feel confident that she’s meeting grade level standards. If we ever choose to re enroll her in public school, I know she’ll be on pace with her peers, and honestly, at this rate, she’ll likely be ahead.

We are so grateful for Mathnasium and for the confidence it’s helped build, not just in math but in learning overall. I would absolutely recommend them to any parent who feels stuck or discouraged.

The center directors are great communicators. They make it really fun for the kids with games, rewards, candy and monthly goals and competitions. It makes my son want to push himself!
