Why read cereal boxes?. . . when you could be learning the planets, the periodic table, the systems of the human body or the states and their capitals? These colorful, wipe-off placemats are a favorite. Since it seems that my children spend most of their time eating, perhaps this is the right place for study! Standard placemat size: 12" x 18". Placemats feature full color front; the reverse side is the same picture outlined in black and white so your child can color or write in the information on the write-on, wipe-off surface.
