Abstract

Subitizing, a quick apprehension towards numerosity when shown a small set of patterned items (Kaufman et al., 1949), has been found to explain early forms of children’s counting development (Wilkins et al., 2023). To examine young children’s number understandings concerning their subitizing activity, we take up the construct of a procept (Gray & Tall, 1993; Gray et al., 2006). Part of a larger study, this paper explains the subitizing activity of two children (Totoro, preschool, and Stephen, kindergarten) evidenced throughout one interview session (approximately 10-15 minutes). Findings evidenced learning opportunities and relationships between participants' subitizing activity and procept development. Future work should focus on transitions in children’s subitizing activity and operation development.
