Developing geometric discourses using DGS in K-3
Developing geometric discourses using DGS in K-3
This paper reports on ideas developed during an analysis of data from a project involving young children (aged 5-7 years) in a whole-class situation using dynamic geometry software. The focus is a classroom episode in which the children try to decide whether two lines that they know continue (but cannot see all of the continuation) will intersect, or not. The analysis illustrates how the children can move from an empirical, visual description of spatial relations to a more theoretical, abstract one.

Abstract
This paper reports on ideas developed during an analysis of data from a project involving young children (aged 5-7 years) in a whole-class situation using dynamic geometry software. The focus is a classroom episode in which the children try to decide whether two lines that they know continue (but cannot see all of the continuation) will intersect, or not. The analysis illustrates how the children can move from an empirical, visual description of spatial relations to a more theoretical, abstract one.
