Mathnasium is a low pressure fun math for kids which is a rare combination! Along with flexibility of the sessions, it makes a great choice for kids and specifically for families where both parents work outside the house.

Our experience with Mathnasium has been nothing short of transformative for our daughter's Geometry studies. Before enrolling, Geometry was a constant source of frustration, but thanks to Mathnasium's focused approach and learning environment, her confidence and understanding have improved significantly. The instructors are incredibly patient and skilled at breaking down complex concepts into digestible pieces, making learning engaging and effective.

Within a few weeks, we saw a noticeable improvement in her grasp of geometric principles, and now she's not just understanding the material, but excelling in it meeting class expectation! Her grades have meaningfully improved, turning a challenging subject into one she genuinely enjoys. Mathnasium has truly been instrumental in her academic success, and we couldn't be happier with the results. It's an invaluable investment in your child's education.

My 2nd grader daughter loves going to Mathnasium. She was ahead of her grade level when she started, and she continues to stay ahead. The instructors are engaged and highly present. The gamification (earning points and ability to "buy" things with the points) is a definite motivator and fun-factor. Suneet has brought positive changes to the structure, e.g. kids bring home a card signed by an instructor showing what they learned in that session. My daughter looks forward to her sessions and would go in everyday if her schedule allowed.
