Discussion of the SEM result estimating a direct path between 6th-grade equality problems and 9th-grade expression evaluation (Model 1c addition, β = 0.36, t = 6.63, p < .001 in Results; β = .44 in Table 5 as cited in Discussion).

"The relation was substantive (β = .44, Table 5) and above and beyond the factors that contribute to general mathematics ability from 6th to 9th grade, suggesting that an understanding of mathematical equality and experience in solving arithmetic problems in a non-standard format directly contributes to later competence in solving algebraic expressions."
