A three-dimensional educational tool that demonstrates periodicity in science and mathematics and a method of using same. The educational tool has a frame with a top template, such as the periodic table of the chemical elements, having a plurality of openings and a plurality of members, representing chemical elements as an example embodiment disposed in the openings. The educational tool provides a plurality of trend blocks that rapidly change a three dimensions display of a plurality of members by selectively raising or lowering the members to demonstrate a particular characteristic of a member in relationship to another member. The trend blocks sit under the frame and the members slide up and down accordingly.

Disclosed is a digital pen that tracks the user's writing and provides useful feedback based on the user's writing. In one embodiment, the pen may provide feedback when the user has written a misspelled word, invalid mathematical expression, or any noncompliant expression. The pen may also provide feedback relating to the user's handwriting. The feedback may be visual, auditory, or tactile, and may be realtime or delayed. Statistics relating to the user's performance may be tracked, uploaded to external devices, and shared with others. This allows the user and interested parties to track the user's progress over time. The disclosed pen will be useful in educational settings.

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.

A system includes several pairable elements and elements to be used for such a system. Each of the elements is adapted to be combined with another element, thereby constituting a pair of elements. The elements include a first indicator where when combining the first indicator of a first element and the first indicator of a second element in a manner specific to the first indicators, the combined first indicators indicate if the first and second elements are a pair. Further, elements include a second indicator where when combining the second indicator of the first element and a second indicator of the second element in an manner specific to the second indicators, the combined second indicators indicate if the elements are a pair and if they are not a pair, the combined second indicators identify the right element to pair with said first and second element.

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.
