The learner represents a collection of equal-sized groups by an addition expression with the same addend repeated once for each group, such as for three groups of three, and connects the expression to the total quantity. This understanding distinguishes equal groups from unequal groups and establishes the foundation for multiplication, without requiring multiplication notation, factors, or larger-number generalizations.
