Abstract: A teaching machine is used with a card to pose a question to a user of the machine and to accommodate both a first case wherein a voice signal is audibly reproduced before the user enters his answer to the question into the machine and a second case wherein a voice signal is audibly reproduced after the user enters his answer into the machine. The machine includes a signal reproducer that cooperates with a card upon which a control signal, a correct-answer signal encoding a correct answer to the question and a voice signal are recorded and that reproduces the recorded signals from the card. A user of the machine enters a test answer to the question into the machine via a keyboard. A first memory responds to the correct-answer signal as reproduced by the signal reproducer for storing the correct answer, and a second memory responds to the keyboard for storing the test answer.

Abstract: Matching question and answer cards in combination with a pair of pivotally interconnected rectangular "flip-flop" plates. The question card bears near the top the letters forming the answer to the question out of the proper sequence, and also bears pictorial representations giving clues to the proper answer. The question card also bears at the central location the same letters in the proper sequence, but intermingled with other letters. The answer card is adapted to be superposed on the question card and bears further clues more explicit than the first-named clues, and a series of holes in its center portion to register with the letters forming the right answer on the question card, so that the proper answer appears through the holes.

Abstract: A programmed learning text including self-test questions for providing immediate feedback to the student on what he has learned. Each question is followed by a plurality of possible answers. Adjacent to each such possible answer is a mottled design printed on the paper. Indentations in the paper, which indentations are concealed by the mottled design, distinguish the correct answer from the wrong answers. After selecting one of the choices, the student touches the mottled design to find out whether his choice is the correct one.

Abstract: An electronic handheld learning aid is disclosed. The learning aid is utilized to teach spelling and alphabetic skills. The learning aid randomly selects a word from memory storage and displays an appropriate number of blank spaces to the operator. The operator attempts to discern the word by entering proposed letters. The operator may also input a word for another operator to attempt to discern. Additional alphabetic format games and learning operations provide training and experience in literary skills. Scoring function and displayed reward phrases provide positive reinforcement of learned skills.

Abstract: A management teaching game is employed to simulate a retail store environment in which a player must pay his opponent a certain amount of play money determined by the number of questions the opponent has correctly answered in a given category corresponding to a given player position. The game includes a gameboard having a first and a second player territory, a pair of player pieces, a pair of dice, a question booklet, a computer for indicating the correct answer to the questions posed in the question book, a score sheet for keeping cumulative totals of correct answers in each category and a predetermined amount of play money. Each player must answer questions in specific categories when his player piece resides on a position in his own territory. When a player's piece is located in a player position in his opponent's territory he must pay his opponent a certain amount of play money in proportion to the number of questions correctly answered by his opponent in the category of that particular player position.

Abstract: An electronic teaching apparatus which utilizes interchangeable flexible overlays with printed pictorial representations in conjunction with a programmable keyboard. An integrated circuit speech synthesizer is utilized to verbally ask an operator to select a particular pictorial representation or to verbally identify a pictorial representation selected by the operator. Upon the failure of the operator to correctly select a particular pictorial representation, the verbal request can be repeated in conjunction with a verbal description of some attribute of the desired pictorial presentation. Each of the interchangeable overlays is coded to allow control circuitry to select a proper sequence of words for a given overlay.

Abstract: A question and answer game includes a book of questions and answers divided into separate categories, as well as a chance-taking device for determining in random matter questions to be asked of participants. The categories of questions are related to a common theme, such as television shows, and each category deals with a separate item within the common theme, such as game shows, situation comedies, westerns, and the like. Each item is further broken down to include a number of shows classifiable within that item. The chance-taking device includes a selector having relatively movable portions and a set of guide cards for directing operation of the selector. The game apparatus also includes a plurality of cards displaying different items within a given category such as television personalities, television shows, and the like. Answers to questions posed by the cards are contained within the book.

Abstract: A toy having a chassis generally configured to simulate a cash register and a mechanism for numerically displaying a price of specific merchandise depicted on a card, is disclosed. The mechanism includes a first and a second panel of the chassis which define a slot wherein the card is at least partially positioned for pictorially displaying the merchandise. A member or plate positioned in the slot supports the card in its position wherein the merchandise is pictorially displayed. The member or plate may be removed through a child actuated lever mechanism to allow disposition of the card behind a plurality of transparent portions of the first panel. The transparent portions of the first panel are configured and adapted for displaying a plurality of numerals when reflection of light is blocked in predetermined parts of the transparent portions.

Abstract: A calculator-type educational device for teaching arithmetic which provides features to motivate a student to greater learning progress including means for reporting the student's arithmetic proficiency by means of post-test statistics that are displayed after completion of a problem set. A dual mode of operation is provided, namely, a first mode in which a selected number of problems is presented for a student to solve at his own pace without any specified time limit and a second mode in which the student is presented problems in a specified period of time, the number of problems being determined solely by how rapidly the student can offer a proposed solution to each such problem.An additional unique feature of the present invention is the availability of numerical limits and factor multiples to which the problem parameters are related.The disclosed embodiment incorporates a microprocessor-based programmed computer in a desk-type calculator configuration.

Abstract: A game or puzzle for pre-school children which exploits both the olfactory and visual senses. The game is formed by a playing board having printed thereon at distinct positions pictures of different odoriferous objects such as fruits having characteristic smells. Superimposed on each pictured object is an identifier constituted by a major circle and a minor circle concentric therewith, the circles being radially divided into colored segments. Each identifier has a distinctive color pattern that differs from every other identifier. The periphery of the minor circle is scored to define a punchout disc, the surface of which is coated with a myriad of minute, rupturable capsules containing an odor-producing substance whose smell is the characteristic odor of the related object. The discs are removed from the playing board to create sockets therein, each of which is surrounded by a major circle ring whose color pattern matches that of the removed disc.
