Abstract
An educational device having a hand-held booklet containing a series of problems with color-coded selectable answers and flat answer card having movable colored tabs and compatible to the booklet. The answer card is typically enclosed in the booklet and can serve as a bookmark. Children record their answers by placing the selected colored tabs into the corresponding positions on the answer card. Children check their own work by comparing site-by-site the colors of the tabs on their answer card with the colors on the corresponding answer key. No pencil is used, answer keys are easily readable, and exercises can be repeated many times since there is no trace of earlier responses. Additionally, students' answer cards and answer key card may be stacked together and create for the teacher a color display of class or group understanding.
