ABSTRACT:
The present invention is a clipboard which attaches by means of a lip provided on a lower edge of the clipboard to a front edge of a typical school desktop so that the clipboard lies flat against the desktop. The clipboard is provided with an upper area which is tilted either left or right with respect to the front edge of the desktop, the angle of the tilt being that required for proper paper placement for writing and the direction of the tilt being dependent upon whether the clipboard is designed for a right-handed or left-handed student. The upper area is provided with horizontal writing lines and is preferably made of an erasable material so the student can mark directly on it. A clip is provided for securing paper to the clipboard. A number line and an alphabet are also provided on the clipboard, with each numeral and each letter being provided with a dot and one or more arrows to indicate proper initial placement and proper movement of a writing instrument to correctly make the numeral or letter.
