The number line comprises an abstract, sophisticated and complex concept in mathematics, while understanding its structure contributes towards the gradual development of the number system. Its use is considered essential in order to meet the needs of pedagogy. This paper presents the problems and misconceptions which may arise from the lack of knowledge on what the number line actually is. The ambiguous association of the number line with the number track seems to give the impression that the number line is a model which simply helps in calculation. This association may also limit the development of number knowledge.
