Bob Moses is 78, but he has the same probing eyes you see behind thick black glasses in photos from 50 years ago when he worked as a civil rights activist in Mississippi. The son of a janitor, Moses was born and raised in Harlem. He's a Harvard-trained philosopher and a veteran teacher.
He started a math training program — the Algebra Project — with a MacArthur "Genius Grant" 30 years ago. The goal is simple: Take students who score the worst on state math tests, double up on the subject for four years and get them ready to do college-level math by the end of high school.
