before i quit teaching last year the ot (occupational therapist) told me not to throw away any of my broken crayons but to give them to molly to color with instead of buying her brand new ones. why you ask? well, she told me that when little kids use the bigger crayons they often hold them in a cave-man-like manner - wrapping their entire hand around them. but when using broken pieces that are smaller, they are forced to grip them more like a pencil thus improving their writing ability. when they are learning to hold a pencil it will be much more natural.
