Most students simply need more focused instruction in order to excel. "The Mathnasium method achieves this and much more, due to the richness and breadth of the Mathnasium curriculum. It is the ideal adjunct for a student?s daily classroom instruction, whether the child is struggling or advanced." Through Mathnasium, Steve is excited about being able to teach math to children in a way that makes sense to them.
