 Who is Eddie, and how were his files born? It s the first week of school in math teacher Kay Toliver s class. The assignment: find out about jobs that people have and how they use math. Eddie s father happens to give him a camera and Vincent, the local photo shop owner, takes Eddie under his wing. Eddie takes his camera along as he tackles his math assignment, and his files "take off." Along the way he meets a judge, a dancer, a restaurant owner, a telephone technician, a sunglasses designer and a TV director. He also consults his Aunt Rosa. Eddie s work brings glowing praise from "Miss T," and a real awareness that math is everywhere.
