Table 3.

Descriptive statistics showing, for each aggregated type of number talk (including both counting and labeling cardinal values of sets), parents’ instances of number talk, instances of number talk per 1,000 utterances, and the percent of number talk instances of that type across the 5 sessions (N = 44).
