Math teacher Ernie Roberts has a busy definition of retirement. He still teaches at Bearden High in Knox County. And every weeknight, he drives to the studios of East Tennessee PBS to teach to an even bigger classroom – a television audience.
Roberts' program, called Mathline, is designed to help students. But Roberts discovered curiosity about math is shared by people of all ages.
In this extended edition of his interview, Roberts tells WUOT All Things Considered host Brandon Hollingsworth that a better grasp on math in childhood can pay big dividends in adulthood.
