Welcome to Mathnasium of South Windsor

Center Director
Hello. I'm Clarence Smith, Center Director/Owner of Mathnasium of South Windsor, your neighborhood math-only learning center. We help kids in grades K -12 understand math by teaching the way that makes sense to them.


When math makes sense, kids leap way ahead – whether they started out far behind or already ahead in math. Our formula for teaching kids math, the Mathnasium Method™ has transformed the way kids learn math for over a decade across 1,000+ centers in the US and Canada:

  • We know how to teach your child math.
    Our specially trained math instructors will teach your child how to understand math in an individual setting – our unique approach enables us to effectively explain math concepts and lend a helping hand to every student. Our tutors foster a caring, encouraging environment that helps kids thrive and learn!

  • We pinpoint your child’s learning needs, meet them where they are, and take them where they need to go.
    Mathnasium instructors use our unique assessment process to determine (with great accuracy) exactly what each child knows and what they need to learn. Next, we design a customized learning plan for teaching the concepts the student needs to master. It doesn’t stop there – our encouraging instructors continually check progress along the way to make sure kids truly understand and retain the concepts we’ve taught. The results are transformative – kids will see measurable changes in attitude, confidence, and school progress.

  • We will help your child overcome homework frustration.
    Our instructors will also set aside time to provide homework help. We help kids understand the homework assignment so they feel better prepared to complete the work at home – underscoring their understanding of concepts and transforming homework frustration into a welcome challenge.

About Our Center


Mathnasium of South Windsor offers fun friendly and effective after school Math programs for children in grades 1-12. Instruction is available in our center or in the comfort of your home with our online Mathnasium @ home offering. Our Math Instructors are passionate about helping kids in the community improve and excel in math through year-round math tutoring and summer math programs. In addition to math tutoring, homework help, final exams, math competition (AMC, Math Counts, etc.) support, SAT/ACT test prep and other standardized test prep sessions (i.e., ISEE, SSAT, etc.) are available.

We serve the South Windsor, Ellington, East Windsor, Windsor, Vernon, Manchester, East Hartford, Broad Brook, Enfield and other nearby communities. Mathnasium of South Windsor supports local public schools through raffles, auction prizes, and donations. Our center is located in the Stop-n-Shop Plaza on Ellington Road.


Summer Program

With the pressures and time constraints of the school year at a standstill, summer is the perfect time to catch up and get ahead in math! Our summer programs are designed to combat summer learning loss. According to researchers at Johns Hopkins University, students “lose about two months of grade level equivalency in mathematical computation skills over the summer months.” The summer slide can have long-lasting effects on a student’s academic life. Come in today to learn how Mathnasium can help your child get ready for next year!


Also available in your area, real-time face-to-face instruction over an internet connection.
