This study examined whether the quality of first graders' (mean age = 7.2 years) numerical magnitude representations is correlated with, predictive of, and causally related to their arithmetic learning. The children's pretest numerical magnitude representations were found to be correlated with their pretest arithmetic knowledge and to be…

A prereading strategy designed to predict events and provide practice in answering questions requiring inferences between text and prior knowledge were used with elementary school students. The performance of experimental groups surpassed that of the control groups on some measures while results were mixed on other measures. (MKM)
