  • Patent number: 9208695
    Abstract: A composition in the target language is parsed into plural different linguistic components, including sound level, grammar level and at least one functional grammar level component. The linguistic components are then expressed on different facets of an n-sided block device representation system according to predefined sets of rules. The facets of the block device may then be selectively examined by the learner to visualize how the target language functions to express the composition with respect to the way sounds, grammar and functional grammar are used. The block device representation system may be computer-implemented, rendering the facets on display panels associated with physical blocks, or as computer-generated images upon a display device.

The body (26) is composed of a number of prism-shaped building blocks (20-24) whose height is equivalent to the height of a story. Each body building block has an oblong, narrow lower side or base (42); when placed side by side, the blocks form the essentially cuboid house body (26) with the area of the base of the house. The roof (28) is a building block with sloping roof surfaces and a base surface (29) whose area is at least as large as that of the base of the house.

  • Patent number: 5275567
    Abstract: Toy blocks and sets of toy blocks containing Braille characters for teaching young, sight-impaired children. A typical wooden block is cubical, comprising a pair of opposite, spaced apart display sides having recessed surfaces. One recessed surface contains a raised Braille character, and the opposite side displays the corresponding alphabetic or numerical character or characters. The recessed sides have borders comprising a bottom tactile-sensing portion that includes a plurality of raised nubs adapted to be touched for orienting the characters properly. Smaller Braille characters are preferably disposed beneath each alphabetic character.

  • Patent number: 5238407
    Abstract: Base-ten blocks for teaching arithmetic to children, in which each block (19) has a projecting boss (27) with curved (bowed-out) sides (29) and an aperture (33) with straight sides (35), so that blocks (19) can be securely joined together to form multiples of units. Integrally made rows (37) of ten blocks each have two end bosses (41) for joining to other rows (37) to make flats (47) of one hundred units. Each flat has four bosses (51) for joining to other flats (47) to make a cube of one thousand units. The blocks have one color for units, a different color for rows of tens, a different color for flats of one hundred, and a still different color for cubes of one thousand. The blocks can be used to teach addition, multiplication, subtraction, division, etc., to children.

    Abstract: Base-ten blocks for teaching arithmetic to children, in which each block (19) has a projecting boss (27) with curved (bowed-out) sides (29) and an aperture (33) with straight sides (35), so that blocks (19) can be securely joined together to form multiples of units. A row of integral blocks (37) has common wall thicknesses (42) between adjacent blocks equal to twice the thickness of the end wall (45) of the row so that the row can be correctly mated with a row of single blocks or end-to-end rows of shorter blocks. Integral rows (37) of ten blocks each have two end bosses (41) for joining to other rows (37) to make flats (47) of one hundred units. Each flat has four bosses (51) for joining to other flats (47) to make a cube of one thousand units. The blocks have one color for units, a different color for rows of tens, a different color for flats of one hundred, and a still different color for cubes of one thousand.

  • Patent number: 5114349
    Abstract: An element for a didactic play, of the type capable of showing several surfaces carrying different representations, which may possibly be combined with the representations of other elements forming a set, in order to compose writings, images or the like, comprising a support, a prismatic body pivoted on the support and carrying on its faces some representations, and a control member carried by the support and capable, when operated, of acting on the prismatic body by causing a rotation thereof along the angle by which each face of the element is replaced by the subsequent face. The control member is formed by a push-button whose operation causes a rotation of the prismatic body in a preestablished direction by acting, by means of a pawl being a part of an inner operating member, onto an arrangement with escapement wheel carried by an end of the prismatic body. The set of such elements moreover includes a tray suitable for containing a number of elements, ordered by lines and columns.

  • Patent number: 5092775
    Abstract: A freestanding visual aid is disclosed which includes instructional material displayed on multiple sufaces of a geometric object to allow the selective display of indicia representing information, on at least one of the surfaces, in a resting position of the geometric object. The indicia displayed by each face of the freestanding object is preferably related to one of a plurality of modes of operation of an apparatus or system with which the visual aid is used. Each surface, for example, may include an explanation of the key functions and command language applicable to a different computer program when the visual aid is used in connection with the operation of a computer or microprocessor system. The freestanding object allows immediate selection of the appropriate instructional information represented by the indicia on a given surface for the particular program employed by the computing system.

  • Patent number: 4997375
    Abstract: Elastic cord interconnected blocks in which each block contains a plurality of deep slots cut to a centrally positioned interior washer-like connecting element having a hole coaxial that can freely pass the elastic cord. The element hole is coaxial with an axial hole formed in the block by the spacing of adjacent block segments, the segment having a spacing for passing a stretched elastic cord and for locking the cord in its relaxed state. Unusual shapes can be formed with several interconnected blocks.

  • Patent number: RE33785
    Abstract: A geometrical structural system is made up of a plurality of nodes and shape-coded connectors extending therebetween, each node having a plurality of outer polygonal elements. The outer edges of each element are bordered by end edges of other elements and each element has an opening therethrough corresponding to the outer side edges of each element. Each opening extends radially into a hollow space centrally of each node. The connectors are elongated and have opposed connecting ends with a cross-sectional configuration corresponding to a cross-sectional configuration of an opening in one of the element faces for insertion therein.
