This electronic game tests children on the basic operations of arithmetic. Children entered both a problem and their answer to it. If the answer was correct, the green light flashed reinforcement. If not, the red eye lit up. (Eek!) An advertisement published just before Christmas 1975 proclaimed, "the Novus 'Quiz Kid' might just make a Whiz Kid out of Jr." The toy sold for $15.
As a kid, you have a toy or game to improve your math skills?
