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.

The present invention provides an educational toy simulator which comprises a base member and a set of peg pieces. The base member is formed of multiple layers, and one or more cut outs are formed in the base member for receiving the corresponding peg piece. The cut outs and the peg pieces are formed with a contoured, stepped or tapered structure to prevent the peg pieces from coming in contact with the image display member. A slot is formed in the base member to slidably receive an image display member for displaying a picture through the cut outs. A depth of the peg pieces is smaller than a depth of the corresponding cut outs. Since the image display member is slidably received in the slot, the displayed pictures may be changed from time to time thus providing capabilities for introducing more vocabulary to a learner in a playful way.

The present invention relates to a kit used for educational and fun purposes that provides components for creating and visualizing complex geometrical shapes. The kit includes small spheres and pegs that can be assembled into multiple geometric shapes, such as polyhedrons. The shapes are created from separate spheres used as vertices that are connected using pegs. Inner spheres including two holes are placed inside the pegs wherein the holes are used for rotating the shapes both horizontally and vertically. A stand includes horizontal spinning rods and vertical rods that are used for rotating the shapes to enable students to visualize and understand the shapes from all angles. The shapes can be assembled and disassembled as per the preferences of a student. The outer spheres, pegs and inner spheres are manipulable parts that provide hours of fun and learning and help students to learn different aspects of geometry.
