摘要:
An assembly for teaching mathematical concepts includes a plurality of interlocking components (10), each having at least one connecting end so that the components can be combined in any order or length. Each component (10) is assigned a mathematical value according to its length, and this value may be indicated by indicia on its face or by color coding. A base (16) is also provided for retaining the columns of components (10) in vertical formations. Means are provided on the platform of the base for engaging the bottom component in each column.
摘要:
An educational toy telephone (100) is provided and includes a telephone base (104) and a removable handset (102). A numerical keypad is provided by which an input telephone number may be entered into said telephone. The telephone further includes a microprocessor (164) and memory associated therewith for controlling the various functions of the toy telephone and storing a user-defined programmed telephone number. A message controller (168) is provided, responsive to an output signal from the microprocessor (104). The message controller (168) stores at least one pre-recorded message consisting of at least one of individual tones, patterns of tones, and a voice message. The microprocessor (164) compares telephone numbers entered into the keypad (130) against the pre-defined telephone numbers. The voice controller (168), responsive to the microprocessor, audibly reproduces the at least one pre-recorded message when the comparison performed by the microprocessor determines that the input telephone number matches the pre-defined telephone number.
