Ordinality is the understanding of numerical order and relationships (such as "more than" or "less than") without necessarily understanding the specific quantity represented by each number. J.T.'s understanding that 3 is more than 2 and 2 is more than 1 demonstrates his grasp of ordinality. Cardinality, on the other hand, refers to understanding that a specific number represents a specific quantity (such as recognizing that "3" means "three objects"). Chronological order refers to the sequence of events over time, and one-to-one correspondence involves understanding that each object corresponds to one number or symbol.
