Exploring K-2 Children Understandings of Visual Representations in Algebraic Reasoning

This project explores how children in grades K-2 understand visual representations of algebraic concepts. For instance, children create tables or graphs to organize information about the relationship between two quantities. They might use graphs and diagrams to explain their mathematical thinking and develop their understanding of relationships in numbers and operations. The project uses data gathered in K-2 classrooms and via interviews with children to describe their use of the visual representations. This exploratory project aims to develop learning trajectories as cognitive models of how children in grades K–2 understand visual representations for algebraic relationships.
