ABSTRACT:
A portable auxiliary desk top article is constructed for temporary positioning onto a work surface arm of a student desk to enlarge the desk's work surface area. The article comprises a first substantially rigid flat surface member and a second substantially rigid flat surface member hingeably attached together. A pocket structure is attached to an underside of one of the flat surface members. The pocket structure is open-sided on two sides and is intended to fit over the work surface arm of the student desk to hold the article in place. When folded out, the flat surface members present an enlarged work surface area for the student, significantly larger than that provided by the work surface arm of the desk.
