    Abstract

    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.
