The most meaningful learning happens when we show students how math connects to the world around them.

What Parents are Saying
You'll never meet another tutor
like Ms. Kero. She goes above and beyond to communicate with me regularly, keep me updated on my son’s progress, and even connects with Brian's teacher when needed. She is genuinely invested in his success.

My daughter was so anxious about Algebra, and it was heartbreaking to watch. After her first tutoring session, I immediately saw Elena calm down and her confidence grew tremendously over the next few months. She went from a 56 to an 84 on the Algebra Regents!
- 8th Grade Parent
My son actually looks forward to his math tutoring sessions! I wish Ms.Kero taught every subject. She's truly a one-of-a-kind teacher and human. We feel very lucky to have come across Courtside Math and are so grateful for all she does.
