This paper investigates how primary students’ knowledge of the structured number line develops over time. Effective number line use is impacted by an understanding of this graphic as a representation that encodes information by the placement of marks on an axis and an appreciation that these marks are representations of length rather than labelled points. Generally, the results revealed development of number line knowledge over time. However, although correlations between number line items were positive, they were only moderate or low. Additionally, there was low shared variance between items even though students solved the same items in three consecutive years. Noteworthy were the statistically significant gender differences in favour of boys over the 3- year-period − findings that warrants further investigation.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
