TLDR
This article investigated the developmental predictors of children's fraction concepts and procedures at the end of fourth grade in a 2-year longitudinal study and found that number line estimation, attentive behavior, calculation fluency, and working memory made unique contributions to the acquisition of fraction arithmetic procedures.About:

Quality of Explanation as an Indicator of Fraction Magnitude Understanding.
TL;DR: In this article, a sample of 71 fourth-grade students at risk for learning to reason about their mathematical thinking and conclusions was used to evaluate their explanations of their mathematical reasoning and conclusions.

TL;DR: Results indicate that verbal skills were the most consistent predictor of successful word problem solving in these tasks, arithmetic skills only predicted the correct solution of word problems containing calculations, spatial skills predicted solution rates in the presence of a visual representation, and general reasoning skills were more relevant in simpler problems that could be easily solved using heuristics.
