Our Results

At Mathnasium, we help kids understand math by teaching the way that makes sense to them. Children who consistently attend sessions at our learning centers enjoy a transformative learning experience and make huge strides in the classroom.

Attitude: When math makes sense, kids develop a more positive attitude toward math.

Understanding: Mathnasium teaches for understanding, giving students the ability to succeed in any math environment. As Larry Martinek, Mathnasium’s Chief Instructional Officer notes, “It's pretty easy to forget things you memorize and near impossible to forget things you understand."

School Progress: When kids learn math in a way that they truly understand, they achieve greater success in the classroom.

Mathnasium of Clayton Parent Testimonials


"We saw fantastic results after enrolling our daughter in Mathnasium!! In 6 months, she went from having a D in math to a B. We couldn't be more thrilled!! My only regret was not enrolling her sooner!


"My son is always very motivated and confident after sessions, and that's a big deal for us."


"Thanks a lot Mathnasium! Linda and the team have been so helpful to my son in gaining confidence and being excited about math. He really looks forward to going to his sessions each week and the staff does a great job treating the kids with patience and kindness. This has been a nice thing for our family." 


"I love it... and more importantly, my son loves it! The director does a great job of clearly explaining the program and the workers are thoughtful, kind, and calmly motivating. Thanks to everyone at the Clayton Mathnasium- it has been a very nice addition to our family."


"I can't say enough good things about Mathnasium's program and Linda, who manages the Clayton Mathnasium. My daughter had earned acceptable grades (B or better) through the 7th grade, so my wife and I pressumed she had gained the math skills neccessary to progress. Midway through the 8th grade she began to fail homework assignments, tests, etc. I sat with her one evening to assist her with a concept she was stuggling with and it became immediately apparent that she had significant fundamental mathematical skill gaps/deficiencies. My daughter winded up receiving a very low C for her final semester grade of 8th grade, however it was largely in part to a ton of extra credit work the teacher assigned to help her out. So, I reached out to Mathnasium who had recently opened a location in Clayton. I spoke with Linda for about 30 minutes explaining the issues I had noted. She listened intently and let me know that my daughter is not alone. We have been going to Mathnasium on a weekly basis ever since and the progress my daughter has made has been nothing short of amazing... she is on track to earn an 'A' in her first semester of hign school, Algebra 1! A very big thanks to Linda and her awesome staff for helping my daughter learn the skills neccessary to excel in mathematics!"
