Primary students’ knowledge of and errors on number lines

Diezmann, Carmel M. & Lowrie, Tom (2006) Primary students’ knowledge of and errors on number lines. In Grootenboer, P., Zevenbergen, R., & Chinnapan, M. (Eds.) 29th Annual Conference of the Mathematics Education Research Group of Australasia, July 2006, Canberra.


This paper reports on fifth graders’ proficiency with number line tasks in an interview situation. The results revealed that at least 10% of students were unsuccessful in using a simple number line effectively. Additionally, some students’ explanations suggest that they do not appreciate that the number line is a measurement model rather than a counting model. This study concludes with recommendations for explicit instruction, a note of caution for interpreting number line items on numeracy tests, and avenues for future research.

Search Google Scholar™

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.
