A construction teaching set for education. A polyhedral block body has first and second divided members and provided by engaging and assembling of the first and second divided members. Each of the first and second divided members has a rectangular plane, a plurality of rectangular inclined surfaces adjoining sides of the rectangular plane, triangular connectors formed between the adjacent rectangular inclined surfaces, and a plurality of vertical skirts extending from the plurality of rectangular inclined surfaces and the triangular connectors. A connection bar has a protruding fastener at one end or both ends to be selectively connected to one among a first fastening hole passing through the rectangular plane, second fastening holes passing through the plurality of rectangular inclined surfaces, and third fastening holes formed in a pair of the vertical skirts adjoining each other. A coupling unit generates coupling force for the first and second divided members.

A first tread pattern display system for new tread patterns includes a first upper sidewall part, a second upper sidewall part, a first tread shoulder part, a second tread shoulder part, and a middle tread part. The first upper sidewall part removably attaches to the first tread shoulder part by a plurality of projections extending from the first upper sidewall part to corresponding recesses in the first tread shoulder part.

A system for coding without compilation includes: a module assembly connected to a user terminal and a function information providing server through a network and including a plurality of modules; and a function information providing server including a function information reception unit receiving function information from the plurality of modules, a function action order generation unit generating a total sequence for a function action order based on the function information, and a function action information transmission unit transferring a command word to the module based on the function action order, in which the command word includes at least one of unique information of a next module relayed next to the module which operates based on the function action order and function number type function information to be executed in the next module, and the command word is sequentially transferred to the module relayed based on the function action order.

Disclosed are a Chinese character structuring member, a system of mortise and tenon joint structures of Chinese characters formed by the Chinese character structuring member and a method for inputting Chinese characters. An entity component of Chinese characters includes the following three structures: an entity component provided with a connecting mechanism at a middle and/or one end or both ends of the entity component configured to join with other entity components of the Chinese characters; an entity component provided with a connecting mechanism entity component extending from one end of the entity component to the other end of the entity component without exceeding the entity component of the Chinese characters; and an entity component provided with at least one connecting mechanism on the entity component that includes a plurality of sub entity components connected end to end and rotatable at the joint.

Described herein is are apparatuses for facilitating learning through the use of one or more senses. One apparatus includes a puzzle having a plurality of pieces that form a numeral. The puzzle includes a shape that matches the numeral, and a number of the plurality of pieces equal to the numeral.

Disclosed are mortise and tenon joint structures for Chinese characters formed by building members having the same or different configurations, and a method for inputting Chinese characters by using the building members. The Chinese characters are de-structured such that each Chinese character consists one or more radicals which are formed by the mortise and tenon joint structures or variants thereof. The variants of the mortise and tenon joint structures are formed by shift, rotation or combination of shift and rotation of the building members of the mortise and tenon joint structures. This establishes an inputting method between the Latin letters and Chinese characters.

An interconnecting alphabet toy corresponding to at least one letter from a book, including a plurality of main bodies, at least one protruding portion disposed on at least a portion of at least one side of at least one first of the plurality of main bodies, and at least one protrusion-receiving groove disposed on at least a portion of at least another side of at least one second of the plurality of main bodies to receive the at least one protruding portion therein, such that the at least one first of the plurality of main bodies and the at least one second of the plurality of main bodies interconnect to form the at least one letter.
