A system and method for augmenting cognitive retention of mathematical skills via the use of combinatorial and repetitive competitive activities. More specifically, such combinatorial and repetitive competitive activities comprising the use of a set of objects having one or more associated numerical values for each object. The objects distributed in rounds to students. The students attempting to develop a mathematical expression that solves for a solution value by combining the numerical objects with mathematical operators.

The present invention discloses a system and method for recognizing objects placed together using capacitance sensors in conjunction with the RFID technology. A structure that is made with a material of high dielectric constant and a RFID tag that comprises a unique identification code (UID) of an object is embedded with the object. With the objects recognized, the spatial structure or the spatial distribution formed by them is derived and corresponding sensory feedbacks are provided by the system.

There is provided an abacus calculation type mental arithmetic learning support device or the like which is also effective for strengthening a capacity for storing arrangement of beads in addition to a capacity for operating a bead of an abacus and is also suitable for measuring an abacus calculation type mental arithmetic capacity, and supports to learn abacus calculation type mental arithmetic by a calculation exercise for operating an abacus-like screen. With a structure in which an abacus-like operation screen is output to a touch panel of a computer and a state of a bead is changed based on an abacus calculation rule when the bead is selected by an operator so that the same calculation exercise as the abacus can be performed, the computer is operated to enable non-display of a change in the state of the bead in a calculation process and to display the state of the bead after the change in a stage in which a calculation ending operation is accepted. Moreover, it is preferable to perform non-display of a number to be an answer in each stage of the calculation process as well as a change in the arrangement of the beads.

A math game using a deck of playing cards and a set of randomly generated numbers. In one embodiment, a method of playing includes dealing each player a set of cards from a deck of cards. Each card from the deck is marked with either a numerical operand or an arithmetic operator as indicia. Players alternate turns by rolling a set of dice to generate a set of numbers. During each turn, each player discards one or more cards among the player's set of cards by placing the one or more cards onto a discard pile corresponding to an outcome of a mathematical operation performed on the set of numbers.
