Summary: We have come to accept that children's appropriation of written numbers is not automatic or simple. Studies of children's use of notation point to different types of notational practice. In a recent study (Cayton, 2007) we found that some common strategies of children for representing large numbers were correlated with different levels of understanding of our base-ten system. In this paper, we explore the connections among three representations of the number system, addressing the question: Are there differences in how children represent (through production and interpretation): numbers in writing; numbers orally; and numbers conceptually?
