Abstract
A teaching apparatus including a casing with two windows therein, and a plurality of buttons in front of one of the windows. The buttons are aligned with answers, for example answers to mathematical questions, visible in such one window, and one question is visible in the other window. If the button in front of the correct answer is pressed, the question disappears and the same or a different question appears in such other window. If one of the buttons in front of the incorrect answers is pressed, nothing happens, i.e., the question remains in view. The set of questions and answers can be changed, because the questions and answers are both on tapes containing a large number of questions and answers. The tape bearing the questions is mounted on spools in a transparent cylindrical cup, the tape extending around the inner periphery of the cup. The cup is integral with a cam shaft rotatably mounted in the casing, the shaft including cams engageable, one at a time, by levers connected to the buttons to cause the shaft and cup to rotate.
