Although number sense has historically been difficult to define in the educational literature, operational definitions of the construct typically consist of a collection of early numeracy skills or “number sense components” such as quantity discrimination, rote counting, and one-to-one correspondence. Consequently, assessments of number sense tend to measure a wide variety of these skills.
