Students' responses to fraction unit's concepts. About 2.1%~26.1% high graders, the major mistakes were changing and neglecting the object of units. About 19.5%~42.7% high graders were toward to think that each fraction appearing in the same contexts of assumption of ego to have the same deal of unit. When the number of contexts was larger than unit, about 36.2%~40.5 high graders can't throw the un- necessary messages away.
