In this paper the authors give a range of examples that illustrate how elementary school teachers can begin to develop children's number sense through the use of calculators before standard algorithms are taught. The incidents we report arose in a research project in which elementary school children were given free access to calculators from their first days at school. Examples of the ways in which the children were able to explore number concepts and computational procedures are given, together with a brief summary of the results of extensive written tests and interviews comparing children with and without long-term exposure to calculators.
