Welcome to Mathnasium of Boerum Hill

Center Director
Hello. I'm Karen Ostrowski, one of the Educational Directors of Mathnasium of Boerum Hill, 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.

Mathnasium of Boerum Hill opened in 2011 and was the fastest-growing Mathnasium in the country two years in a row! Our center primarily serves Downtown Brooklyn, Boerum Hill, Carroll Gardens, Cobble Hill, and Fort Greene.

Our location is now part of a network of 6 Mathnasium centers which includes 3 locations in Manhattan, 2 locations in Brooklyn, and 1 location in Bucks County, PA. The Boerum Hill location provides another great opportunity for children in NYC to learn to think like natural mathematical thinkers and become “Crazy About Math!”

The owners of our network of Mathnasium learning centers, Tammy and Marc Goldberg, have been instrumental in helping to evolve the Mathnasium curriculum over the years alongside the Mathnasium Corporate Headquarters Education Department.  Tammy and Marc have been innovators and collaborators on many curriculum development initiatives through which they have personally written 2,000+ pages of curriculum materials that are currently being used in Mathnasium Centers nationwide.
