ATTENTION Elementary School Principals and PTA and PTO members!

At Mathnasium, the nation's leading math-only learning center franchise, we are dedicated to helping children learn and understand math in ways that can change their lives forever.

Our dedication to children does not end there.  As part of our effort to assist all children with math and STEM education, we have partnered with National PTA in their STEM + Families Initiative.  You can learn more about this initiative here: // gladly offer our assistance hosting a Math Night at nearby elementary schools. 

Math Nights are turn-key 2-hour events featuring engaging games developed by Mathnasium to involve families and increase interest in STEM subjects through an enjoyable and shared math experience.  Our goal is to get to know local families and show them that math can be fun.

We have hosted and will continue to host annual Math Nights at Academy Street Elementary School (Bayport Blue Point School District) and Idle Hour Elementary School (Connetquot Central School District), and we would like to schedule Math Nights at all the local elementary schools!  Members of the school community are invited to attend (look for an announcement / invitation from the school).
