A building toy is provided that includes panels that connect magnetically at their edges, or to a base structure, to construct scenes, structures, and vehicles, or combinations thereof, along with related accessories.

The invention relates to devices and methods designed to promote speech and language development and, in particular, learning upper and lower case letters, shapes, colors, numbers and phonemes to improve articulation. Phonemes, which form one of the basic building blocks of speech, are distinguishing speech sounds that differentiate one word from another, e.g. the sounds d and t in the words bid and bit and are the smallest phonetic units that can carry meaning.

A device for presentation and training in project work or group work includes a housing with cages configured in the interior to be adjacent to a surface segment at least in each corner and/or in the edges and/or in grids. A permanent magnet is arranged in each of the cages so that all magnets can orient themselves. The housing includes an electronic unit having a data memory on which at least one ID number is stored, a switch, and a transmitter connected to the switch and having an antenna. The transmitter wirelessly transmits the ID number to a controller and trigger a further process, which assigns the device a meaning within the scope of the project or group work. A related set comprises at least two devices, and can be used for presentation, training, project work or group work. A related method for digitalizing manually compiled specifications uses the set.

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.

A student aid assembly includes a magnetic panel that has a front side, a rear side and a peripheral edge. A plastic coating is non-removably attached to and covers the front side of the panel. The plastic coating comprises a dry erase board for displaying an erasable writing material. The plastic coating has a plurality of indicia positioned thereon and includes a blank space is bounded by a perimeter line. The blank space defines a name area to allow a person to write a name therein. The indicia includes a plurality of reference areas to assist a student with answering a school question.

A child development toy including a box and a set of flexible sheets. The box defines an interior compartment and an aperture extending into the interior compartment through a side of the box. Each flexible sheet has a corner with a bounded slit surrounded by material of the sheet configured to receive the corner of another sheet inserted through the slit. The set of sheets is configurable as a chain of sheets. Each two adjacent sheets of the chain is releasably connected by a connection formed by a corner of one of the two adjacent sheets inserted into the slit of the other of the two adjacent sheets.
