There is nothing wrong with doodling as long as she has self-control to refrain from doodling on anything official that has to stay clean. While she may in fact be bored to death, doodling by itself is not necessarily a sign of boredom. She may simply have focus issues and doodling is her way of coping.
I think we have both coping and boredom going on. Math and language arts keep her attention. Science and social studies, where she is not challenged, are her biggest art studios! Well, just realized that some of her math tests get pretty decorated, too...
