ab: 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.
