Abstract: A kit including a multi-compartmented tray with provision for required student articles, such as pencils, crayons, glue, paste, paint, erasure sticks, and the like. The tray walls are of a height substantially less than the defined diameter of the associated jars to conveniently project the jars relative to the tray compartments for ease of access thereto. Jar positioning apparatus includes a pneumatic "L" shaped chamber mounted within an "L" shaped support bracket, wherein the "L" shaped chamber includes a button member directed through the bracket, whereupon depressing of the button member ejects an associated jar upwardly relative to the bracket while tilting the bracket forwardly due to a pivotal connection of the bracket to the floor of the compartment.
