Developing young children's multidigit number sense

Enrichment for mathematically gifted students in the elementary school needs to extend beyond puzzles or busywork and support the development of mathematical power through a differentiated curriculum. This article describes a series of enrichment experiences that were designed to develop young gifted children's understanding of large numbers, which was central to their investigation of space travel. Although large numbers are not traditionally included in the mathematics curriculum for young children, the children in this group responded enthusiastically to the enrichment experiences. These experiences provided the children with an opportunity to understand the large numbers they encountered in science resource material and to develop their mathematical power.
