“Similar and Equal…”: Mathematically Creative Reflections About Solids of Children with Different Attachment Patterns

This chapter deals with mathematically creative processes in early childhood. The concept of the interactional niche in the development of mathematical creativity is introduced, which combines interactionistic theories of socio-constructivism, sociocultural theories, and a psychoanalytically based attachment theory in order to describe mathematically creative processes of children during early childhood development. Data are collected in the interdisciplinary project Mathematical Creativity of Children. Two empirical cases of children and their mathematically creative processes, from engaging in a task in a cooperative mathematical situation, are presented.
