We received an email from Grace's teacher that said " Grace has been doing so well during Tiger Time. We are working on multiplying fractions by a whole number and changing improper fractions into mixed numbers. She has been helping lead the class and has been able to demonstrate mastery of both skills. Her hard work is paying off." It let us know it was So worth sending her to Mathnasium.

My boys absolutely loved their experience at Mathnasium. They loved playing the math games with the teachers and friends and earning tokens for prizes. They had so much fun!

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

Our family wanted to focus on confidence and the understanding that if you don't know an answer right away, or if you don't understand the equation, that is okay. Part of math is learning how to work the problem and what questions to ask. Our child has greatly improved their math skills and does not feel discouraged when they are confused or don't get the right answer. Our child now understands how to work through a problem, and in return, test scores and self esteem have greatly increased.

Thank you for reaching out! I'm delighted to share my experience with the math class. My child has not only gained a stronger understanding of mathematical concepts but has also developed a genuine interest in the subject. The teaching approach is both engaging and supportive, making it easier for my child to grasp challenging topics.

My daughter was falling behind in the 2nd grade, we began Mathnasium in November that year, and by the Spring, her grades improved, she was ahead of the average learning curve and had great reviews from her teacher about her improvement and that the work with Mathnasium was clearly working.

Mathnasium is really a great resource for children. My daughter was behind in math due to the pandemic and online learning. Within 7 months she improved significantly and not only understands math more but loves it.

Tanya was amazing -- she was warm and inspiring, and embraced our daughter with compassion and care during every interaction. She is an excellent role model for young women. The staff is composed largely of outstanding HS students. At first, I felt that my 9th grade daughter might feel intimidated by this, but she really enjoyed working with students/peers with whom she could relate. Even on the days that she was reluctant to attend, my daughter always emerged from her Mathnasium sessions with a big smile and in a great mood.
