发明名称 Educational box toy and method
摘要 An educational box toy and method for teaching one or more of the alphabet, numbers, colors, spacial problem solving and hand-eye coordination, utilizes a series of four blanks dimensioned and configured for selective erection by folding into a corresponding series of four box-like members, each box-like member having six faces, and each blank comprising nine panels so that the total number of panels provide a sufficient number of surfaces upon which to display alpha-numeric characters arranged for viewing in alphabetical order and in numerical order during folding of the blanks to erect the box-like members and during unfolding to return to the blanks in desired learning sequences. The series of blanks are shown dimensioned and configured such that each consecutive box-like member of the series is smaller than and receivable within a larger next consecutive box-like member of the series for enabling the box-like members to be assembled into a nested arrangement of box-like members.
