Summary: Based on a synthesis of the literature, a model for number sense was formulated, and validated. The major constructs incorporated in this framework were elementary number sense, conventional arithmetic and algebraic arithmetic. To trace the development of number sense components a longitudinal study was conducted. One hundred and forty 1st grade students were tested individually on four different occasions. Data analysis suggested that the hypothesized components contributed to the latent construct number sense. A latent growth model showed that elementary number sense and conventional arithmetic adopt a linear growth rate, while algebraic arithmetic needs a stabilization period after a significant growth period.
