Primary Students' Success on the Structured Number Line
Diezmann, Carmel M.; Lowrie, Tom; Sugars, Lindy A.
Australian Primary Mathematics Classroom, v15 n4 p24-28 2010
Number lines are part of people's everyday life and are frequently used in primary mathematics as instructional aids, in texts, and for assessment purposes on mathematics tests. There are two types of number lines; (1) structured number lines, which are the focus of this paper; and (2) empty number lines. Structured number lines represent mathematical information by the placement of marks on a horizontal or vertical line which has been marked into proportional segments. Empty number lines are blank lines which students can use for calculations. In this article, the authors focus on how students' knowledge of the structured number line develops and how they become successful users of this mathematical tool. (Contains 5 figures.)
