Our Results

At Mathnasium, we help kids understand math by teaching the way that makes sense to them. Children who consistently attend sessions at our learning centers enjoy a transformative learning experience and make huge strides in the classroom.

Attitude: When math makes sense, kids develop a more positive attitude toward math.

Understanding: Mathnasium teaches for understanding, giving students the ability to succeed in any math environment. As Larry Martinek, Mathnasium’s Chief Instructional Officer notes, “It's pretty easy to forget things you memorize and near impossible to forget things you understand."

School Progress: When kids learn math in a way that they truly understand, they achieve greater success in the classroom.
