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!

Great instructors and personalized attention. Friendly staff that engaged my son on a subject with which he's easily discouraged.

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.

Tanya is AMAZING to work with! You can tell she wants the kids to succeed. She is a great motivator and cheerleader for them. My kids loved working with her and her staff!

Thank you for your passion. We don’t know what we would have done to get our kids caught up to speed with the 18 months pandemic chaos, if it’s not for your help.

Our daughter started Mathnasium last fall and absolutely loved it. She has improved so much and feels confident in school with Math assignments. She was a bit behind when she started a new school and Mathnasium has helped her so much. Thank you to Tanya @ Mathnasium Johnston. We will be back this summer

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

Mathnasium was a great resource for us and Tanya was so helpful and accommodating to my son’s needs.

My son went there as a junior with low math skills and left with the ability to bring up his Aleks score to get into his program at DMACC.

He will probably always struggle with math, but Mathnasium helped him get to where he needed to be for his future career.

Would highly recommend Mathnasium in Grimes.

My son attended this summer. He had excellent instruction, was kept engaged the entire time he was there, and he felt his time was very worthwhile. As a parent, I am very happy with Mathnasium and the quality of instruction.
