Examined development of number concepts among participants from the beginning and end of first grade, third and fifth grades, and university. Found that the numerical distance effect appeared in all groups. Found size congruity effect began to appear at the end of first grade. Proposed a model of internal representation of magnitude asserting that there are two different representations. (ERIC)
