Counting on represents addition as increasing a known quantity by a specified number of units. For sums within 20, the learner can start with one addend, typically the greater, and identify the result by moving forward the number of units in the other addend; a number line makes this relationship visible and distinguishes counting on from recounting the entire collection. This understanding supports mental addition and later place-value strategies.
