Double sided student lap boards with polar coordinates made in the U.S.A. by our own OptiMA Graphics. Double sided lap boards with one side printed with a polar coordinate chart and the other side plain white.
Sturdy non-magnetic 9" x 12" or a larger 12" x 18" individual student lap board with rounded corners and bull-nosed edges are perfect for any classroom.
The blank, plain white side makes the boards more versatile than single sided lap boards.
Tip: It is not recommended to clean these boards with anything containing ammonia which is found in most glass cleaners.
