http://themorechild.com/2007/12/26/why-elementary-teachers-overlook-the-verbally-gifted-child/I spoke w/ a teacher friend of mine about this. She said she felt the same way when she was in school. She said imagine that you can understand things on a 5th=6th grade level but are forced to have directions and stories and content on a mid2nd grade level. With a math precocious child, you can subject accelerate more easily. With a verbally precocious child, he/she can handle higher level content in science, social studies, history, art appreciation etc.
