  5. The spatial arrangement of sets influences how difficult they are to subitize. • Children usually find rectangular arrangements easiest, followed by linear, circular, and scrambled arrangements (Beck-with and Restle 1966; Wang, Resnick, and Boozer 1971). • This progression holds true for students from the primary grades to college.
