Children’s Mapping between Non-Symbolic and Symbolic Numerical Magnitudes and Its Association with Timed and Untimed Tests of Mathematics Achievement
Figure 3
Mean accuracy on the numerical magnitude comparison tasks as a function of grade and distance.
Solid lines indicate data on the symbolic magnitude comparison task (MGrade 1 = .89; MGrade 3 = .92), and dashed lines indicate data on the non-symbolic magnitude comparison task (MGrade 1 = .88; MGrade 3 = .92).
