If you can imagine a juggler spinning dishes on sticks in front of a live TV audience, Do the Math Director John Lenko says you can probably imagine what he does on Tuesdays and Wednesdays from 4-5 p.m. "I've got to switch live between three anchors, three camera operators, callers waiting on line, multiple video and audio sources and get us on and off the air on time. If those dishes start to slow down and wobble, I have to keep them spinning." Lenko laughed. Do the Math returned to the airways on Oct. 3, after a summer hiatus, to help tutor Kern County students with their math homework. Lenko works for the Kern County Superintendent of Schools, and the show originates from the superintendent's TV studios. In fact, another employee of the superintendent, Laurie Maclin, is the executive producer, and she came up with the idea for the show. Do the Math features full-time, public school math teachers who have been transformed into TV personalities. More
