S ummary . 60 children, aged between 4 and 7 years were given problems designed to assess their understanding of number invariance involving numbers of objects within their subitizing range, numbers outside their subitizing range but within their counting range, and large numbers they were not allowed to count. The results indicate that number invariance is initially developed for small numbers and then extended into the counting range and beyond.
